This podcast explores the history and uniqueness of the Swift programming language, its modern features and beginner-friendly syntax, updates and future prospects including asynchronous programming and concurrency, and the limited future it may have outside of Apple platforms compared to competitors like Rust and Kotlin.
Swift was developed by Chris Lattner, a highly regarded computer scientist who did his PhD on compilers and it was made public by Apple in 2014 as the future of programming on their platforms.
Swift emphasizes safety and makes it harder to create certain types of programming errors compared to Objective C, providing a modern and safer language for developers.
Deep dives
Swift's development and creator
Swift was developed by Chris Lattner, a highly regarded computer scientist who did his PhD on compilers. Lattner first gained attention for his work on the LLVM compiler system. Apple hired him to work on LLVM, and as a side project, he developed Swift. Apple made Swift public in 2014 as the future of programming on their platforms.
Reasons for Apple switching to Swift
Apple switched to Swift because of concerns with Objective C. The syntax of Objective C was not appealing to some developers, and it was also a superset of the unsafe C programming language. Apple wanted a modern and safer language, which led to the development of Swift. Swift emphasizes safety and makes it harder to create certain types of programming errors compared to Objective C.
Usage and future of Swift
While Swift is an open-source language with community involvement, Apple still maintains control. It is primarily used for developing apps on Apple platforms. There have been attempts to use Swift in other domains, like machine learning and backend web development, but it is not widely adopted outside Apple's ecosystem. Swift is a multi-paradigm language that combines features from different languages and offers a modern and progressively disclosed syntax. The language continues to evolve, adding new features like asynchronous programming and exploring ideas from the Rust programming language. However, its complexity and competition from other languages may limit its growth beyond the Apple niche.
Swift is one of the top ten most popular programming languages in the world by almost any ranking or measure. Yet, it's also a niche language. That seems contradictory, until you know that it's only widely used for building apps on Apple platforms. In this episode, we discuss the history of Swift, what makes it unique, and where it's been going.
