Swift

Use the language which works well for the developers you have or have available. If you're starting, building a first iteration is far more important than worrying about what language might be best to solve a problem you may never have.

When hiring, look for developers, not "node developers" or "java developers" having people who recognise and are willing to adapt means you can have the flexibility you will need to solve as-yet unforeseen issues. Hire people who are wed to a specific language and you will be bound to that language, regardless of whether it's most appropriate or not.

For online banking, it'll be less computation intensive and more data intensive. So, Rails will be better than Python. I'll not recommend Node.js as it's not as scalable as those. If I had to choose indepently I would took Go.

I would go with Flutter for the front end because it is easy to use once you learn Dart, has components for both Cupertino and Material Design, performs well, and has great documentation. For the backend, I've never used PHP so I don't know how good Laravel works, but I would usually use Node.js because of its large ecosystem, or Aqueduct, because if you use Flutter than you can use Dart on both the front and back end.

You could check out Ionic. Angular won't help in creating a mobile app, but with Ionic you can do it, and it comes from Angular. On the other hand, it isn't clear if you're building a mobile webapp or if you need it to be a native APK.

About Flutter, it is really limited for webapps, it's heavily oriented towards creating native Android and iOS apps using Dart.

My Recommendations: Front End: Flutter because of developer tooling and powerful declarative widget system Back End: Node.js or Go because Node.js has a large ecosystem and Go has a good built in http setup Database: Cloud Firestore because of ease of use, NoSQL, and the ability to set data from the client

If you go with react / react native I advice you to go with node. Why ? I first didn't believe coding in javaScript everywhere (back, front and db queries) was making life SO much more easy. I still followed the advice, in the end this is a huge relief. For a small startup project with 1/2/3 devs, using only one langage increases efficiency a lot. You can switch very fast from a topic to another.

Hi, I worked on a lot of Android applications that needed native components and fine-tuned communications protocols, so multi-platform apps was impossible or way too expensive. There are a lot of examples over the years of companies beginning with multi-platform framework and finally switching to native e.g. https://medium.com/airbnb-engineering/react-native-at-airbnb-f95aa460be1c

My advice would be, as you are at the beginning of your startup and know React well: Develop your first app in React to showcase your product, add features, remove ones and find your product-market fit. Switch to native only if you have really bad performances issues or features that you cannot implement in React. It will save you a lot of times ! There is very few developers who are experts in Android & iOS !

Native apps are not going to die. Especially not Swift because now Swift can be used to develop cross platform macOS and iOS apps due to the new macs having M1 chips.

I would suggest to bet more on Swift! I have developed act in React and Javascript in the past and played around with Swift a little... the performances of native code vs Javascript are way too slow compared to swift native app!

Now even more than ever M1 chip will give a boost, but if it gives a boost to JS it will give a boost also to native apps. I would seriously consider Swift more than Javascript, React or even Electron!

Mastering SwiftUI by Big Mountain Studio is a great reference manual.

A good way to practice is to spend a few days or weeks working on reading/learning. Then, try to build your own thing.

There’s so much in Swift and SwiftUI, it will a dozen apps before you become really good at it and even then, you’ll be often referring to Stack Overflow for help.

Also check out raywenderlich.com, that site is filled with relevant tutorials and books.

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.

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).
