Ruby vs Swift: What are the differences?

What is Ruby? A dynamic, interpreted, open source programming language with a focus on simplicity and productivity. Ruby is a language of careful balance. Its creator, Yukihiro “Matz” Matsumoto, blended parts of his favorite languages (Perl, Smalltalk, Eiffel, Ada, and Lisp) to form a new language that balanced functional programming with imperative programming.

What is Swift? An innovative new programming language for Cocoa and Cocoa Touch. Writing code is interactive and fun, the syntax is concise yet expressive, and apps run lightning-fast. Swift is ready for your next iOS and OS X project — or for addition into your current app — because Swift code works side-by-side with Objective-C.

Ruby and Swift can be primarily classified as "Languages" tools.

"Programme friendly", "Quick to develop" and "Great community" are the key factors why developers consider Ruby; whereas "Ios", "Elegant" and "Not Objective-C" are the primary reasons why Swift is favored.

Ruby and Swift are both open source tools. Swift with 48.4K GitHub stars and 7.76K forks on GitHub appears to be more popular than Ruby with 15.9K GitHub stars and 4.25K GitHub forks.

Airbnb, Square, and Codecademy are some of the popular companies that use Ruby, whereas Swift is used by Uber Technologies, 9GAG, and Square. Ruby has a broader approval, being mentioned in 2530 company stacks & 1140 developers stacks; compared to Swift, which is listed in 993 company stacks and 541 developer stacks.

Hello!

I'm a developer for over 9 years, and most of this time I've been working with C# and it is paying my bills until nowadays. But I'm seeking to learn other languages and expand the possibilities for the next years.

Now the question... I know Ruby is far from dead but is it still worth investing time in learning it? Or would be better to take Python, Golang, or even Rust? Or maybe another language.

Thanks in advance.

Hi Caue, I don't think any language is dead in 2022, and we still see a lot of Cobol and Fortran out there, so Ruby is not going to die for sure. However, based on the market, you'll be better off learning Goland and Python. For example, for data science, machine learning, and similar areas, Python is the default language while backend API, services, and other general purpose Goland is becoming the preferred.

I hope this helps.

I feel most productive using go. It has all the features I need and doesn't throw road blocks in your way as you learn. Rust is the most difficult to learn as borrow checking and other features can puzzle a newcomer for days. Python is a logical next step as it has a huge following, many great libraries, and one can find a gig using python in a heartbeat. Ruby isn't awful, it's just not that popular as the others.

Another reason to use python is that it is not compiled. You can muck around in the interpreter until you figure things out. OTOH, that makes it less performant. You really need to think about your use cases, your interest in lower-lever versus high-level coding, and so on.

I enjoy coding in Python. I think it's minimalistic and readable syntax and lang features are just unparalleled. They are perfect for prototyping and for the software engineering in general. If I'm not wrong Gitlab marked Python as #2 popular language after JavaScript. Beyond that, Python ecosystem and areas of usage are enormous. In areas like ML/DL, it's important to know Python to leverage variety of existing tools and frameworks.

Then, I have learned and worked with Golang. I use it where I think I would need a slightly better performance than in Python. Plus, relatively small and self-contained executable is a great thing to have. If you plan to write distributed systems, extend Kubernetes or do similar things I think Golang is a great choice. It's also simple and straightforward, especially when you want to do effective multithreading. Although I don't like that Golang is more low-level than Python. Sometimes I feel like I need to implement myself too much things.

Now, about Rust. It's my second try to learn Rust. First time I decided to learn Golang as I understood it in 30mins or so while I was struggling to compile/do anything meaningful there for quite a bit. So I personally don't think Rust is super easy. I have got back to learning Rust as it's going to fill one of gaps in my problem solving toolkit - let me write low-level system programs (e.g. linux kernel modules). I don't want to learn "obsolete" C/C++ (my reasons are similar to why Google has recently introduced Carbon - a replacement for C/C++ codebases). If you are not going to tight your life with system-like programming, Rust may be an overkill for you.

Finally, I have never coded in Ruby, so are not going to comment it.

Since you are very experienced, picking up a language will not take you more than a week. Rust is a very new language. Many startups are still experimenting with it. Golang is very popular nowadays. You can see a lot of golang jobs in the market. The best part is, compiled code is single binary and has a minimal footprint. Rails is a compelling framework; believe me, many websites like Shopify, GitHub, GitLab, etc., are powered by the rails framework. You can also leverage the power of metaprogramming in Ruby. Python is memory and CPU intensive. It is not as performant as the other three. If you want to go into Data Science, Python is the language. Good luck, buddy.

Hello, I am still a student and would like to ask a question. Currently, I am developing in mobile development with Flutter in the frontend and Python in the backend part. Right now I have to make a choice about developing a mobile app or developing a backend to progress more professionally. My questions are as follows:

1) If I prefer the mobile application area, will I only work with the Ui/Ux developer with the front-end and code the designs in Swift Kotlin languages, am I responsible for the back-end software?

2) I have a product that generates new ideas so I like to control the development and work there because the backend is the brain, but are they independent from each other in the backend mobile application? Is the mobile app developer responsible for the backend software?

3) I don't like graphic design because I don't like it if it's not perfect and I get stressed. Am I responsible for the graphic design in the mobile app?

4) Is a mobile app developer also a backend developer?

I know these are very simple questions, but they are very important to me. Thanks for your answers.

Hi Hüseyin! 1-2) In my experience If you are a Mobile Applications Developer you will have the following responsabilities: - Develop (not designing) both functionality and screens of the app you are working - Consume (not develop) third party or self company owned APIs or Backend services - Distribution tasks. - Mantainance tasks. Now, there will always be companies wishing you know the whole thing (ui/ux, backend, frontend, mobile, cd/ci, data science, etc.). And of course it will be helpful for you to know a little bit of the stuff around mobile development, but it's not very common since it's not part of the responsabilities of a mobile app dev.

3) No, you are not responsable for the designs of your application, that's why companies have Product designers, ux designers, ui designers for preparing the screens, logos, color palettes, etc for products. As a developer your job is to see and examine the designs and take them from Figma, InVision, Zeplin, etc to the Code editor.

4) This is the thing, if you are working as a Mobile Developer you might know about Mobile development, not backend, not frontend, not ui ux. BUT if you know a little about backend that might be helpful although backend should not be your responsability.

I hope this makes sense to you. Cheers!

As a mobile developer, I'm usually a member of a larger team and it's usually another person's responsibility to develop the backend/API, and another person's to do the UX/design. Very very few teams use cross-platform tools like Flutter or React Native, because tools like those tend to make mediocre apps that scale poorly and are impossible to debug, so make sure to get familiar with Swift/iOS or Kotlin/Android (or both).

Hi! I think most of your questions led to these answers:

  • Mobile software developers don't responsible for the back-end part, or even graphic design. Of course, the back-end part should be done by a back-end developer. The graphic design, I'd say that if you work on a start-up, you might be the one who does since there isn't much manpower there, but in the larger company, they would have a designer especially in UI/UX. You'll have a mockup for the application that you need to follow. As a developer, you're expected to code, not design.

  • I've said that the responsibility isn't yours, but of course, you'll have an advantage over others if you know UI/UX, or back-end as well. That would help you a lot to be a good mobile developer.

Good luck!

Hey there, we are looking to develop our own layer 1 blockchain. We're splitting the responsibilities for origination, clearing, and settlement across three independent but cooperating node networks. We've gotten our Proof of Concept up using Ruby on Rails for the nodes, you can see it as the attached link. So far, so good. Now we are looking to convert it into a distributable and are trying to figure out which language is the best for this.

Essentially our needs from the language are: solid networking tools and speed, very fast execution of basic actions, some parallel execution, and able to compile the end product into an easy to distribute and use package for end users.

I was learning Rust, but I have a healthy amount of experience with Swift and right now, it's only me coding. I've only done iOS coding, but have built a fintech app from scratch that's now in the app store so I'm pretty familiar with the language and its benefits. Haven't experimented with Vapor or any of the application development tools, and I wanted to know if it is a crazy idea to develop a blockchain node in Swift instead.

Pick Rust. Rust can provide all what you need and has been a major language in blockchain/cryptocurrency industry. Swift is slower than Rust and does not have such support in the networking and domain field. Swift tooling is great only on macOS, therefore you are likely to have troubles on other platforms.

You can use swift of course. It’s more of a question of being performant.

You really want to try some basic operations and find what’s most performant for you.

Rust is wonderful for cloud applications requiring heavy concurrency, it has compile time checking for such things.

Go and C++ could be more performant in your case. Swift is really quite an obtuse language, with a lot of features, some which may complicate your implementation.

Also, you want to consider the market of developers who could help build it. If you use Go or C++ there is a larger collection of people who know the languages than there is with swift.

If asking about employment opportunities, native will never die out. There will always be opportunity for work in native mobile applications. There are also many advantages of using native over cross platform such as always having access to the latest APIs and developer libraries that may not be available to cross-platform without some native development involved or can wait until someone develops a bridge for you.

If you are asking about what you should develop with first? It really depends. React-Native is great for building proto-types or basic MVP application that doesn't require any of the latest and greatest features Apple has to offer at the moment. But if you're asking what to learn? I would say native will always give you a larger advantage as it will give you a good foundation in mobile development and provide you access to the latest native libraries. It is also a useful skill that can give you an edge in cross-platform mobile like react-native because you will most definitely encounter a situation where you will have to go down to the to native side to extend functionality or utilize APIs that are not yet out of the box.

"Should I just learn Swift first due to the pros of the native apps?". React Native builds Native Apps. Technologies like ionic does NOT build native apps, but React Native does it.

Learning Swift seems to be a really bad idea from my point of view. Learning JavaScript is all what you need. Why? Because then Frontend, Backend, and Mobile Dev, is simple, because it's all JavaScript.

The decision comes down to your goals and needs.

If you want to be able to create any kind of iOS app, simple or complex, learn Swift. It's indispensable if you're building specialised apps like video editing, augmented reality, machine learning or anything that uses iOS-specific APIs such as App Clips.

But if you just want to create apps that make HTTP requests and display static content such as text or basic video and music, React Native would do just fine, and you can publish the same code to Android. This is a no-brainer choice if you're on a low budget.

And if you know both, you can use both in the same app. You can add React Native screens or components inside a Swift app.

Ruby on Rails is far from being dead. In fact, this is a very popular choice in early-stage startups, given how fast and easily it allows them to launch their product and iterate on it.

Even at more mature companies, you'll still find a ton of opportunities. Not for internal tools or legacy codebases, but for actual production workloads: web apps, APIs, etc...

Some may tell you that Ruby doesn't scale, but is it really Ruby that doesn't scale, or the code they wrote?

Languages have trends. Sometimes, recruiters will try to take you one way or another to meet their own agenda. Don't always listen to what you hear. Long live Ruby! Long live Rails!

You can’t directly compare RnR and Javascript, since the first is a framework (Ruby would be the language), and Javascript is a language. RnR even uses quite an amount of Javascript. I think that Ruby, and Rails, are design by improving on previous languages, and shifting the perspective from speed to readability and general developer friendliness. Opposed to that, Javascript did not have any design goals at all, and seems to be repeating the errors of all language designs that existed before. “Knowing Javascript” would not be a selling point to me when hiring someone, there should be mentioned specific javascript frameworks. And I’d always try to find someone who has experience in multiple languages. So my advice is to to learn RnR first, you get a head start, Javascript will just come along with it. And you can distinct yourself from other people that claim web development knowledge because they have done one javascript tutorial :-)

I know I'm cheating by recommending both, but that's because I don't think you can go wrong either way.

I've been working with RoR full-time for the past 3.5 years and I really enjoy it. Compared to JavaScript, it's so much easier to read which is amazing from a team collaboration perspective. As for the perception that it's dead, when I recently started looking for new opportunities, I received probably an average of 10-15 calls a week from recruiters looking for people with RoR experience. Also, if you look around for average wages of developers of different languages, Ruby is fairly high up there (higher than JavaScript if I recall correctly), probably because there are fewer of us around and we can command a premium.

However, that said, if your goal is to find a full-time engineering position quickly, then JavaScipt certainly is the flavor of the month and any product with a frontend component will need it. Even our enterprise SaaS platform which didn't use a frontend framework (React, Angular, Vue, etc...) required us to integrate JS packages and write custom ones. JavaScript is probably more versatile than Ruby at the moment and it seems like new frameworks are being written for it all the time, but remember that Ruby was also the preferred language by almost all companies 5-10 years ago.

At the end of the day, I would go with the language that you enjoy writing the most as you'll be using it a lot in your workplace. If you aren't having fun at work, that's a lot of time spent suffering.

Yo Matt,

I've been in the Ruby on Rails game for twenty years. For the last ten, Rails has been declared deceased. ;) But in reality, Rails is still going strong. The jobs are highly paid and fun. All the pros you list are valid. Yes it is a beautiful language, the OO makes sense, it's dynamic and expressive, and the ecosystem is top shelf. What's to dislike? There are a lot of Rails websites out there. And new ones get created every day too.

Now, to address the elephant in the room....

Ruby is quirky. Since the syntax is pretty different from PHP, and core developers being opinionated, some people just see drama. When Node.JS got slightly usable, they moved over to that. Node.JS is very c/PHP-like after all in its syntax. Many engineering managers will just select the ecosystem that is biggest. Node.JS is a lot bigger. But if you don't care about going a little off the beaten path sometimes, Ruby in my opinion still, after all this time, gives me joy when I use it.

Also important: to this day, I can build everything I want. Ruby, Rails and many gems are being actively maintained. Security vulnerabilities are discovered and corrected. New developments still find their way into the language. For myself, I know that the anemic JS standard library would just frustrate me to no end.... every wheel is invented time and again. Ruby's standard library isn't as voluminous, but it's a lot more diverse and useful.

I've yet to see a non-native application that I felt performed as well and/or provided the same user experience with Cordova/PhoneGap/Xamarin. Frankly, at best they all seemed like underpowered web applications deployed to a sandbox that ran on a phone. They didn't feel "slick" or "mobile-first" and in some cases the performance was unacceptable. At previous companies, we built a few of these apps at the client's insistence, and in every case, they re-engaged us about 18 months later to re-write the app(s) natively.

We are doing some research on React Native and Flutter, but I am not yet convinced that they can provide the same level of experience and performance as native, though I am trying to keep an open mind.

We chose React Native over native Android and iOS development because of React Native's cross-platform capabilities. React Native has really matured over the years, developing a native feel, with simple and intuitive APIs. The community is also huge, filling in any gaps in the default APIs. These are also the reasons why we didn't choose other hybrid mobile tools. Largely, other hybrid mobile tools don't have the same mobile feel and close connection to the underlying mobile APIs.

At a larger scale, the control that native development offers beats React Native's simplicity. However, at this early stage, it's worth the trade-off. Maintaining two mobile teams and two mobile apps, as we iterate the product rapidly would not be practical. Plus, there is always the escape hatch of native modules if more control is needed.

As a startup, we need the maximum flexibility and the ability to reach our customers in a more suitable way. So a hybrid application approach is the best because it allows you to develop a cross-platform application in a unique codebase. The choice behind Ionic is Angular, I think that angular is the best framework to develop a complex application that needs a lot of service interaction, its modularity forces you (the developer) to write the code in the correct way, so it can be maintainable and reusable.

I was considering focusing on learning RoR and looking for a work that uses those techs.

After some investigation, I decided to stay with C# .NET:

  • It is more requested on job positions (7 to 1 in my personal searches average).

  • It's been around for longer.

  • it has better documentation and community.

  • One of Ruby advantages (its amazing community gems, that allows to quickly build parts of your systems by merely putting together third party components) gets quite complicated to use and maintain in huge applications, where building and reusing your own components may become a better approach.

  • Rail's front end support is starting to waver.

  • C# .NET code is far easier to understand, debug and maintain. Although certainly not easier to learn from scratch.

  • Though Rails has an excellent programming speed, C# tends to get the upper hand in long term projects.

I would avise to stick to rails when building small projects, and switching to C# for more long term ones.

Opinions are welcome!

We have a lot of experience in JavaScript, writing our services in NodeJS allows developers to transition to the back end without any friction, without having to learn a new language. There is also the option to write services in TypeScript, which adds an expressive type layer. The semi-shared ecosystem between front and back end is nice as well, though specifically NodeJS libraries sometimes suffer in quality, compared to other major languages.

As for why we didn't pick the other languages, most of it comes down to "personal preference" and historically grown code bases, but let's do some post-hoc deduction:

Go is a practical choice, reasonably easy to learn, but until we find performance issues with our NodeJS stack, there is simply no reason to switch. The benefits of using NodeJS so far outweigh those of picking Go. This might change in the future.

PHP is a language we're still using in big parts of our system, and are still sometimes writing new code in. Modern PHP has fixed some of its issues, and probably has the fastest development cycle time, but it suffers around modelling complex asynchronous tasks, and (on a personal note) lack of support for writing in a functional style.

We don't use Python, Elixir or Ruby, mostly because of personal preference and for historic reasons.

Rust, though I personally love and use it in my projects, would require us to specifically hire for that, as the learning curve is quite steep. Its web ecosystem is OK by now (see https://www.arewewebyet.org/), but in my opinion, it is still no where near that of the other web languages. In other words, we are not willing to pay the price for playing this innovation card.

Haskell, as with Rust, I personally adore, but is simply too esoteric for us. There are problem domains where it shines, ours is not one of them.

In 2015 as Xelex Digital was paving a new technology path, moving from ASP.NET web services and web applications, we knew that we wanted to move to a more modular decoupled base of applications centered around REST APIs.

To that end we spent several months studying API design patterns and decided to use our own adaptation of CRUD, specifically a SCRUD pattern that elevates query params to a more central role via the Search action.

Once we nailed down the API design pattern it was time to decide what language(s) our new APIs would be built upon. Our team has always been driven by the right tool for the job rather than what we know best. That said, in balancing practicality we chose to focus on 3 options that our team had deep experience with and knew the pros and cons of.

For us it came down to C#, JavaScript, and Ruby. At the time we owned our infrastructure, racks in cages, that were all loaded with Windows. We were also at a point that we were using that infrastructure to it's fullest and could not afford additional servers running Linux. That's a long way of saying we decided against Ruby as it doesn't play nice on Windows.

That left us with two options. We went a very unconventional route for deciding between the two. We built MVP APIs on both. The interfaces were identical and interchangeable. What we found was easily quantifiable differences.

We were able to iterate on our Node based APIs much more rapidly than we were our C# APIs. For us this was owed to the community coupled with the extremely dynamic nature of JS. There were tradeoffs we considered, latency was (acceptably) higher on requests to our Node APIs. No strong types to protect us from ourselves, but we've rarely found that to be an issue.

As such we decided to commit resources to our Node APIs and push it out as the core brain of our new system. We haven't looked back since. It has consistently met our needs, scaling with us, getting better with time as continually pour into and expand our capabilities.

What is Ruby?

Ruby is a language of careful balance. Its creator, Yukihiro “Matz” Matsumoto, blended parts of his favorite languages (Perl, Smalltalk, Eiffel, Ada, and Lisp) to form a new language that balanced functional programming with imperative programming.

What is Swift?

Writing code is interactive and fun, the syntax is concise yet expressive, and apps run lightning-fast. Swift is ready for your next iOS and OS X project — or for addition into your current app — because Swift code works side-by-side with Objective-C.

What are some alternatives to Ruby and Swift?
Python
Python is a general purpose programming language created by Guido Van Rossum. Python is most praised for its elegant syntax and readable code, if you are just beginning your programming career python suits you best.
JavaScript
JavaScript is most known as the scripting language for Web pages, but used in many non-browser environments as well such as node.js or Apache CouchDB. It is a prototype-based, multi-paradigm scripting language that is dynamic,and supports object-oriented, imperative, and functional programming styles.
PHP
Fast, flexible and pragmatic, PHP powers everything from your blog to the most popular websites in the world.
Java
Java is a programming language and computing platform first released by Sun Microsystems in 1995. There are lots of applications and websites that will not work unless you have Java installed, and more are created every day. Java is fast, secure, and reliable. From laptops to datacenters, game consoles to scientific supercomputers, cell phones to the Internet, Java is everywhere!
Groovy
It is a powerful multi-faceted programming language for the JVM platform. It supports a spectrum of programming styles incorporating features from dynamic languages such as optional and duck typing, but also static compilation and static type checking at levels similar to or greater than Java through its extensible static type checker. It aims to greatly increase developer productivity with many powerful features but also a concise, familiar and easy to learn syntax.
