202207041909 AppStorage extension for strongly typed keys

#appstorage #swiftui

The @AppStorage property wrapper for observable access to UserDefaults keys is stringified.

To get a strongly typed key access, I oriented myself on the @Environment(\.keyPath) wrapper and my experience with SwiftyUserDefaults and its subscript-based access.

// Use defaultValue from the key:
@AppStorage(\.showOnboarding) var showOnboarding
