Editor's intro
Editor's intro
Building for iPhone means learning three things at once: the Swift language, Apple's frameworks (now mostly SwiftUI), and Xcode itself. Apple's own tutorials have become excellent, and a handful of independent teachers fill the gaps. This feed favors current SwiftUI material; older UIKit resources appear only where UIKit is still the right tool.
You'll need a Mac for almost everything here. Start with a structured beginner path, build one small app end to end, then use the intermediate picks for persistence, networking, and architecture. The advanced items cover concurrency and the language's deeper design — the parts that separate App Store-ready apps from demos.

100 Days of SwiftUI
100 Days of SwiftUI by Paul Hudson is the most complete free path into iOS development. Each day is about an hour: a short lesson, a few checkpoints, and regular consolidation days where you build a small app on your own. It covers Swift fundamentals before moving into SwiftUI, and it's updated as Apple's frameworks change. The daily structure is the real feature — it turns a big, vague goal into something you can show up for.
