SignalingStorage

Observable and Signaling Keychain and Defaults Storage

This example application showcase a couple of ways to make an "Observable" abstraction around UserDefaults and the Keychain. Making it possible to be notified in one part of the app when another part of the app changes a value stored in UserDefaults or the Keychain.

• ObservableDefaults: An abstraction around UserDefaults that implement ObservableObject. Will publish change events whenever any value changes.
• SignalingDefaults: An abstraction around UserDefaults that signals whenever a given value change. The benefit of SignalingDefaults over ObservableDefaults is that SignalingDefaults only signal changes on a per value basis.
• ObservableKeychain: An abstraction around the Keychain that implement ObservableObject. Will publish change events whenever any value changes.
• SignalingKeychain: An abstraction around the Keychain signals whenever a given value change. The benefit of SignalingKeychain over ObservableKeychain is that SignalingKeychain only signal changes on a per value basis.
