Prephirences

Provides consistent protocols (PreferencesType, MutablePreferencesType) for accessing diverse backends like UserDefaults, Keychain, and plists, reducing boilerplate code as shown in the README's usage examples.

Supports RawRepresentable enum keys and MutablePreference wrappers, enabling compile-time safety for preference keys and values, illustrated in the Accessing and Modifying sections.

Allows combining multiple preference sources (e.g., UserDefaults, iCloud) into a single interface via CompositePreferences and prefix-based organization with ProxyPreferences, detailed in the Composing section.

Enables custom transformations, archiving of complex objects (like UIColor), and default value fallbacks through PreferenceTransformation, with examples in the Transformation and Archiving section.
