Swift is a programming language developed by Apple in 2014. It’s designed to work with their suite of products, including watchOS and tvOS. It’s meant to be more stable, more concise and less error-prone than Objective-C, which came before it and was first introduced way back in 1984. If you know Objective-C programming, though, you’re at an advantage: the majority of Objective-C is still represented in some form in Swift.
Nonetheless, it’s no surprise that Swift is a really popular programming language, with a broad-based open source community constantly uploading new projects and sharing information. It’s still rising in popularity according to TIOBE, so it hasn’t even peaked yet. If you want to work on development for Apple’s products, then you’re in very good company. This list contains some of the best open source libraries, hand-picked from among Github’s top rated Swift UI libraries.
What’s the benefit of these libraries? Rather than building something yourself, from scratch, you can see how other people do it, and even use the open source libraries available to build your app way faster than you could otherwise. In the end, it’s all in how you bring it together to make the final product – but these libraries will definitely help you on your way!
