Apples programming language Swift is now only 4 years old and is currently tied at number 10 with Objective-C in rankings. Programmers have started moving over to Swift to develop programs for the Iphone, Apple Watch and Mac computers. By the third quarter of 2017 Swift surpassed Kotlin (Android language supported by Google) as the fastest growing programming language.
If you are looking into switching or learning a new language Swift would be a safe way to go. With Apples growth over the years and Androids lack of new ideas we can expect a higher demand for Swift developers in the near future. Especially with Apply announcing its plans for the “Biggest Iphone yet!”.
