About Swift Programming Language

Swift is a general-purpose, multi-paradigm, compiled programming language developed by Apple Inc. and the open-source community. Swift is designed to work with Apple's Cocoa and Cocoa Touch frameworks and the large body of existing Objective-C code written for Apple products.

About Kotlin Programming Language

Kotlin is a cross-platform, statically typed, general-purpose programming language with type inference. Kotlin is designed to be fully interoperable with Java, and the JVM version of its standard library depends on the Java Class Library, but type inference allows its syntax to be more concise.
