Introduction to Swift and Playgrounds
Learn about the origin of Swift and some of its basic syntax.
Through a series of exciting activities and challenges, you’ll learn key coding concepts as you solve puzzles in the Swift Playgrounds app. As you progress through the course, you’ll build your computational thinking skills, and see how coding can be fun as you explore examples of coding in everyday life. Fortunately, Apple has a language for writing apps for the Mac, iPhone, and iPad, and you can have fun learning it, as well. It’s called Swift. Released in 2014, Swift’s popularity amongst. TL;DR This is the first of a four-part series that documents building an app from start to finish. In this first part, Rony will cover the basics of the Swift language. Jack Watson-Hamblin takes over in Part 2, covering the basics of working with Swift in Xcode before moving into getting started with the Interface Builder, storyboards, and structs and finally gluing it together and customizing. Swift Playgrounds, Apple’s Answer to Learning to Code. If your goal is to write programs for macOS or iOS, you need to learn Swift. Who better to learn coding for Apple devices from than.
