Swift is another general-purpose, multi-paradigm, compiled programming language developed by Apple Inc. It was introduced after Objective C and is a powerful and instinctive programming language for iOS, macOS, tvOS, and watchOS.
Swift comprises all the modern features that allow developers to develop apps without putting any extra efforts. Writing code in Swift is interactive; the syntax is compact yet expressive. It is designed to work with Apple’s Cocoa Touch and Cocoa frameworks as well as the sizable body existing Objective-C code written for Apple products.
It is easier to learn.
Less code, less legacy
Its main advantage is its clean syntax, which makes it simpler to read and write.
It is comparatively less error-prone which helps to develop a secure app.
It is not dependent on any other parent language, which makes it a lot easier to maintain
It provides several speed benefits during development, which in turn saves cost.
It supports dynamic libraries which enable on-going Swift apps to link against latest versions of the Swift language as it evolves.
