Cocoa Touch (iOS) vs Swift: What are the differences?
Developers describe Cocoa Touch (iOS) as "The Cocoa Touch collection of frameworks includes everything needed to create iOS apps". The Cocoa Touch layer contains key frameworks for building iOS apps. These frameworks define the appearance of your app. They also provide the basic app infrastructure and support for key technologies such as multitasking, touch-based input, push notifications, and many high-level system services. On the other hand, Swift is detailed as "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.
Cocoa Touch (iOS) and Swift are primarily classified as "Frameworks (Full Stack)" and "Languages" tools respectively.
"Backed by Apple" is the top reason why over 5 developers like Cocoa Touch (iOS), while over 241 developers mention "Ios" as the leading cause for choosing Swift.
Swift is an open source tool with 48.2K GitHub stars and 7.71K GitHub forks. Here's a link to Swift's open source repository on GitHub.
Slack, Lyft, and Zillow are some of the popular companies that use Swift, whereas Cocoa Touch (iOS) is used by Snapchat, Third Iron, and Apple. Swift has a broader approval, being mentioned in 979 company stacks & 526 developers stacks; compared to Cocoa Touch (iOS), which is listed in 32 company stacks and 18 developer stacks.

By mid-2015, around the time of the Series E, the Digital department at WeWork had grown to more than 40 people to support the company’s growing product needs.
By then, they’d migrated the main website off of WordPress to Ruby on Rails, and a combination React, Angular, and jQuery, though there were efforts to move entirely to React for the front-end.
The backend was structured around a microservices architecture built partially in Node.js, along with a combination of Ruby, Python, Bash, and Go. Swift/Objective-C and Java powered the mobile apps.
These technologies power the listings on the website, as well as various internal tools, like community manager dashboards as well as RFID hardware for access management.
At the heart of Uber’s mobile app development are four primary apps: Android rider, Android driver, iOS rider, and iOS driver. Android developers build in Java, iOS in Objective C and Swift. Engineers across both platforms land code into a monolithic code base that ships each week.
They use some third-party libraries, but often build their own, since “Many open source libraries available are general-purpose, which can create binary bloat. For mobile engineering, every kilobyte matters.”
On Android, the build system is Gradle. For the UI, Butter Knife binds views and callbacks to fields and methods via annotation processing, and Picasso provides image loading.
As for iOS, all of the code lives in a monorepo built with Buck. For crash detection, KSCrash reports crashes to the internal reporting framework.
Excerpts from how we developed (and subsequently open sourced) Uber's cross-platform mobile architecture framework, RIBs , going from Objective-C to Swift in the process for iOS: https://github.com/uber/RIBs
Uber’s new application architecture (RIBs) extensively uses protocols to keep its various components decoupled and testable. We used this architecture for the first time in our new rider application and moved our primary language from Objective-C to Swift. Since Swift is a very static language, unit testing became problematic. Dynamic languages have good frameworks to build test mocks, stubs, or stand-ins by dynamically creating or modifying existing concrete classes.
Needless to say, we were not very excited about the additional complexity of manually writing and maintaining mock implementations for each of our thousands of protocols.
The information required to generate mock classes already exists in the Swift protocol. For Uber’s use case, we set out to create tooling that would let engineers automatically generate test mocks for any protocol they wanted by simply annotating them.
The iOS codebase for our rider application alone incorporates around 1,500 of these generated mocks. Without our code generation tool, all of these would have to be written and maintained by hand, which would have made testing much more time-intensive. Auto-generated mocks have contributed a lot to the unit test coverage that we have today.
We built these code generation tools ourselves for a number of reasons, including that there weren’t many open source tools available at the time we started our effort. Today, there are some great open source tools to generate resource accessors, like SwiftGen. And Sourcery can help you with generic code generation needs:

When we first built the ArifZefen app our focus was around validating our business assumptions and finding a good product fit. Once we got to a few thousand users, it became clear that we needed to make quality a priority and that meant we needed a reliable tool that will allow us to monitor the health of our app. Crashlytics (now Fabric by Twitter ) was on a short list of solutions we closely explored and we were very happy with its ease of integration and the consistency it brought to our Cocoa Touch (iOS) and Android SDK crash monitoring.
Its daily pulse emails were also super informative in giving us a good sense of how each platform was doing in terms of crash-free and new users, daily actives and other relevant session data. These emails also surfaced any anomalies in daily trends, alerting us of any reason for concern. Overall, Crashlytics was instrumental in allowing us to quickly discover and diagnose crashes and it is one of the main reasons we were able to keep our app store ratings reasonable high. But perhaps even more importantly, we were able to set a high quality bar for our users that absent Crashlytics would have been difficult to maintain.
Since the beginning, Cal Henderson has been the CTO of Slack. Earlier this year, he commented on a Quora question summarizing their current stack.Apps

Back in the days, we started looking for a date on different matrimonial websites as there were no Dating Applications. We used to create different profiles. It all changed in 2012 when Tinder, an Online Dating application came into India Market.
Tinder allowed us to communicate with our potential soul mates. That too without paying any extra money. I too got 4-6 matches in 6 years. It changed the life of many Millennials. Tinder created a revolution of its own. P.S. - I still don't have a date :(
Posting my first article. Please have a look and do give feedback.

Swift Java PHP Magneto WordPress #Webhooks Added as the newest feature in #Channelize.io. It was initially hard for me to understand what Webhooks meant. But I got the gist of it. Simple example:
Webhooks are pretty much like our brains. for every task, our brains keep sending signals continuously. notifying us for eating, for moving, for removing our hand from Gas Stove or steam.
Imagine asking your brain if you're hungry, tired or hurt. That would be disastrous! Right?
Webhooks are pretty much the same thing, complete automation for your web development projects triggered by some Events just like our Brain. Take a look at the article below to learn more about webhooks and how it works with Channelize.io. Do give your Suggestions also here.
The performance of Swift is almost the same as that of C++, which is considered the fastest in algorithm calculation arithmetics. Apple had this idea in mind and worked to improve the speed of Swift. For example, Swift 2.0 has beaten C++ in several computation algorithms, such as Mandelbrot algorithm. Objective-C is slower because it contains C API legacy.
Swift is faster than Objective-C, because it removed the limitations of C language and has been improved with the help of advanced technologies that were unavailable when C was developed. As mentioned by Apple, Swift was originally designed to operate faster.
Despite the fact that languages are different, they both integrate, and work with Cocoa and Cocoa Touch APIs, for all Apple platforms. Therefore, a regular app-user would not recognize the difference in operating speed between Objective-C vs Swift. Speed also depends on a programmer’s level and capabilities, since a slow app can be written in Swift as well.
Its performance approaches the one of C++ which is considered the fastest algorithm calculation arithmetics. And Apple strives to improve the speed of Swift. Learn more here https://mlsdev.com/blog/51-7-advantages-of-using-swift-over-objective-c
iPhone app, a new born language, it may good but the IDE, xcode is bad compare with Visual Studio. It just like a baby. playground can only use without connect to other library...you can not do a simply refactor of renaming a variable. You can go to definition and find reference, but you can not go to implementation....I should write them on xcode not here basically it is not the fault of swift, but it tightly to it, unless you want to use a notepad to write it.
Most of our newer apps are written completely in swift, with our older ones and some special cases using a mix of Swift and Objective-C, but with Swift 2, the language is pretty much a must-use. "guard" is <3.
Flutter is coded with Swift v.2.3 and can be run with Xcode v.8.2.1. To launch in Xcode 9.3, the code needs to be migrated to Swift 4.1
Most of the app code was gradually rewritten in Swift for better performance and code maintenance.
