This is one reason it’s becoming the singular programming language for Apple Platforms (iOS, iPadOS, macOS, tvOS, watchOS) and beyond as it’s compatible with Linux, servers and more. Swift is a language that is easier to learn and easier to read, giving it a lower barrier of entry when compared with older languages like Objective-C. Swift is available in the most recent versions of Xcode and can be used to build apps from iOS 7 or later, and macOS devices dating back to Mac OS X 10.9 or later. Swift is based around modern practices that are also seen in other modern programming languages like JavaScript, Ruby and Kotlin. Swift is a new programming language from Apple, built by Apple, that builds on the techniques learned in Objective-C, but modernizes them to include shorter syntax and easier readability, maintainability and safety to prevent crashes.

Swift is more than 2.6x faster than Objective-C and more than 8.4x faster than Python. In 2010, Apple started developing Swift, a new programming language that would rival Objective-C in a few areas–specifically, type safety, security, and better on-hardware performance. Objective-C called NeXT and Apple home where it was the default programming language for NeXTSTEP, OS X and iOS. It started as a programming language that bundled object-oriented programming (OOP) with the likeness of the C programming language. Objective-C has won the hearts of many developers.
