Paul Hudson's SwiftUI patterns packaged as a Claude skill.

Code
Write the full file with toggles, NavigationLink to subpages, and a confirmation dialog for sign-out.✓ Kopiert

Ergebnis: Idiomatic SwiftUI you don't have to rewrite next year.
Fallstricke
Don't mix @StateObject with @Observable — Don't mix @StateObject with @Observable — the skill enforces one or the other; follow it.
