Swift does not stop progressing over time by being increasingly used and, by extension, more popular with developers . The latest TIOBE Index reveals that Swift ranks 10th among the most popular programming languages, down from 14th position last year at the same time. There are two things to consider. The first concerns the top 10 Apple has just entered for the first time. The second point touches the nine other programming languages that are located in front of Swift, all of which already have a few years already. Apple therefore has a place among the popular languages, while Swift was only launched in 2014. Apple has released Swift with the idea of offering a programming language simpler to learn than Objective-C in particular. IOS and macOS applications can be encoded in Swift and more and more developers are switching on it for better performance optimization, in addition to ease of use. We can recall in passing that Apple also targets children with its application Swift Playgrounds for iPad that teaches them the basics of Swift. The idea is to train them from an early age so that they are excellent later.
