Scope

Swift and SwiftUI application code for iOS, iPadOS, macOS, watchOS, tvOS, and visionOS. SwiftUI-first: UIKit and AppKit are covered where the two meet — hosting, representables, scene lifecycle, macOS windows — not as an application architecture in their own right.

Default deployment target for new apps is iOS 26 and its coordinated releases; Swift 6.2 or later with strict concurrency. iOS 27 is the newer SDK and its APIs are marked as such.

Not covered: server-side Swift, App Store submission, ASO, Core Data (SwiftData is the default; say so rather than improvising), and cross-platform frameworks (flutter, react-native).

Architecture is not prescribed. Do not push MVVM, VIPER, or Clean Architecture onto a codebase. Encourage separating logic from views for testability without mandating how. Performance work is a suggestion unless the user asked for a performance pass.
