Swift & SwiftUI Series

A working refresher on the SwiftUI you actually meet in real codebases in 2026: pre-iOS 17 state management, modern @Observable, async/await as the default, and the everyday patterns for networking, navigation, and error handling.

A real SwiftUI debugging note about optional views, overconfident AI advice, and why @ViewBuilder is inherited by body but not by your own computed view properties.

Environment injection, direct initializer passing, and @Binding all share SwiftUI state, but they carry different meanings around ownership, coupling, and interface scope.

A collection of hard-won SwiftUI patterns for memory, async work, and Observation edge cases. Covers view model lifetime bugs, debouncing, async button actions, task ownership, reference cycles, and the tension between @Observable and actors.

Swift's Observation framework rethinks how model objects communicate changes to SwiftUI. This is the first post in my Swift series, walking through @Observable and @State with a concrete drag-coordination class as the running example.
