audit-modernization

Scan for legacy iOS patterns that have modern replacements, with migration guidance for each.

What This Command Does

Launches the modernization-helper agent to identify code still using older patterns and suggest the iOS 17/18+ replacement, including code samples for the migration.

What It Checks

1. ObservableObject → @Observable — classes using the older protocol that should adopt the macro
2. @StateObject → @State — @StateObject declarations on @Observable types (which require @State)
3. Deprecated APIs — calls to deprecated SwiftUI/UIKit APIs flagged with the corresponding @available replacement
4. Combine → AsyncSequence — Publisher chains that translate cleanly to for await
5. Async legacy bridges — withCheckedContinuation calls where a modern async API now exists
