From the first release to the present, Swift is actively developing. Today it has become the main development language for the Apple platform, ahead of the still popular Objective-C language. Swift is an open source programming language, which means it will soon be supported by other operating systems. If you have ever programmed in other languages, then I can assume that after getting acquainted with Swift and with all the variety of its capabilities, you will not want to return to the "old camp." Keep in mind that Swift is dragging its feet and not letting go!
