iOS and Xcode
Set up Xcode and understand how iPhone apps are built.
📖 Key ideas
- iOS apps are built with Xcode on a Mac.
- Swift is Apple's modern language; SwiftUI is the modern UI framework.
- Test on the iOS Simulator or a real iPhone.
- A bundle identifier uniquely identifies your app.
- Publishing needs an Apple Developer Program membership.
💡 Real-life example: Xcode is Apple's workshop: editor, simulator, designer and packing desk in one.
