What is iOS Swift?
Swift is a versatile, multi-paradigm, compiled programming language created by Apple Inc., first launched in 2014. iOS Swift is a robust and intuitive programming language for macOS, iOS, watchOS and tvOS. It is a fast, easy to use and expressive language that is quite popular with new coders and developers. Swift instantly codes faster across the boards once it is released and debugged. It supports Linux and all Apple platforms, which enhances the efficacy of the software. Swift includes memory management software, Automatic Reference Counting (ARC) that manages memory automatically, and is easily operated.
Features of Swift
Swift is open-source, which means that it is not just restricted to Apple platforms, but it can be utilized on Linux and Android platforms as well.
Swift uses type interference and another external parameter to enable programmers to write self-documenting statements without any difficulty.
Since its release in 2014, it has become a programming language of choice for many leading organizations such as Apple, IBM, Lyft, Zillow, and more.
Swift was developed by taking cues from various languages such as Python, C#, and Ruby to become more advanced, interactive, and faster than ever.
