It was 2014 when Apple launched the Swift programming language to make the development of applications for iOS simpler and as immediate predecessor of Objective-C language.
The reception was very warm right away even for the actual validity of the language and the arrival on the market as Swift Playgrounds solutions. More iPad apps are created to learn the basics of the language with tests and tutorials suitable also for children.
This month Swift has entered for the first time in the top-ten of the most popular programming languages in the world, pulling himself in tenth place (last year was the fourteenth) TIOBE index with a 2.2% rate of time preference.
It is a remarkable achievement if we think of a few years since its release, and the fact that Swift has surpassed languages such as Pearl, Ruby, Visual Basic and the same Objective-C.
The reasons for this growth are easy to understand. Not only the interest getting bigger for the development of apps for iPhone and iPad, but also the fact that Swift is an open source programming language and therefore usable even outside the Apple ecosystem.
