There have been several exciting new developments in the iOS landscape in the last few years that make building a native iOS app easier than ever. In this precompiler, we'll build an iOS app from scratch using Swift and SwiftUI. We'll reach out to an external API to fetch and display data; we'll make use of common Apple APIs like Alarm Kit, Map Kit, and Event Kit; and we'll set up some simple unit tests with Swift Testing. You'll walk away with a working app to add to your portfolio and solid intro to the skills and patterns common to iOS development.
