Swift was launched by Apple in 2014 — although it had secretly been in development since 2010. It’s a programming language that was aimed at developing iPhone apps, but in 2015, Apple made it open source.
Since then, it has been becoming particularly popular because it is a lightweight and fast language. It also compiles data much quicker than Objective-C, the language developers used before.
