Kotlin vs Swift: What are the differences?
Kotlin and Swift can be primarily classified as "Languages" tools.
"Interoperable with Java" is the primary reason why developers consider Kotlin over the competitors, whereas "Ios" was stated as the key factor in picking Swift.
Kotlin 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 Kotlin with 28.3K GitHub stars and 3.28K GitHub forks.
Uber Technologies, Slack, and Lyft are some of the popular companies that use Swift, whereas Kotlin is used by Slack, 9GAG, and Rainist. Swift has a broader approval, being mentioned in 993 company stacks & 541 developers stacks; compared to Kotlin, which is listed in 268 company stacks and 208 developer stacks.

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.
Even though still a young language, it feels so at home sitting in the springboot frame and works with vaadin just great. And in itself it has like all the best parts of java, scala, python mixed into one.
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
We use Kotlin both in our Android App and increasingly in our polyglot backend services.
Most of the app code was gradually rewritten in Swift for better performance and code maintenance.
Our native iOS app is built on Swift, and most of the basic function is still written in Swift
