SwiftUI, UIKit lifecycle, and shipping to the App Store
Building iOS apps the way Apple’s documentation teaches it. SwiftUI first — views as value types, the state system (@State, @Binding, @Observable, environment), view identity and lifetime, lists and navigation, layout and animations — plus the UIKit foundations working apps still touch (view controller lifecycle, delegation patterns). App lifecycle and scenes, concurrency on the main actor, persistence choices (UserDefaults, Codable, SwiftData/Core Data concepts), networking with URLSession, notifications, accessibility (VoiceOver, Dynamic Type), and the ship process — signing, provisioning, TestFlight, and App Store review realities. Every explanation names the framework rule, the classic mistake, and a portable principle. Authored from developer.apple.com at the current stable iOS release.
