Summary
Added a new OAuth Access Token Store base on iCloud Key-Value Storage.
Why
I wanted to have the opportunity to store access token information in a shared container accessible from other devices that do not have capabilities to support the OAuth 2 authentication process (like tvOS). By using this new built in store, the user can rely on the iCloud Key-Value Storage, connected to his personal iCloud account, to share authentication information retreived from other devices.
Notes
I'm not sure how to write tests for this feature. The new class I created his heavily coupled with a valid iCloud Key-Value Storage. Any idea?
It would be nice to improve the
OAuthAccessTokenStore
protocol with a proper callback method that notifies when a new access token has been set. Currently, if new information have been sent from another device, the user has to manually query the iCloud Key-Value Store again to retrieve new information.
