Effortlessly sync UserDefaults over iCloud
Zephyr has built in monitoring, allowing it to sync specific keys in the background as they change.

Turn on iCloud Sync in Xcode
In Xcode, open your app's project/workspace file:
- Click on your Project
- Click on one of your Targets
- Click on Capabilities
- Turn on iCloud syncing
- Under Services, make sure to check
- Repeat for all Targets (if necessary)
Integrate Zephyr into your App
Before performing each sync, Zephyr automatically checks to see if the data in UserDefaults or NSUbiquitousKeyValueStore is newer. To make sure there's no overwriting going on in a fresh installation of your app on a new device that's connected to the same iCloud account, make sure that your UserDefaults are registered BEFORE calling any of the Zephyr methods. One way to easily achieve this is by using the UserDefaults Register API.
Sync all UserDefaults
Sync a specific key or keys (Variadic Option)
Zephyr.sync(keys: "MyFirstKey", "MySecondKey", ...)
Sync a specific key or keys (Array Option)
Zephyr.sync(keys: ["MyFirstKey", "MySecondKey"])
Add/Remove Keys for Background Monitoring (Variadic Option)
Zephyr.addKeysToBeMonitored(keys: "MyFirstKey", "MySecondKey", ...) Zephyr.removeKeysFromBeingMonitored(keys: "MyFirstKey", "MySecondKey", ...)
Add/Remove Keys for Background Monitoring (Array Option)
Zephyr.addKeysToBeMonitored(keys: ["MyFirstKey", "MySecondKey"]) Zephyr.removeKeysFromBeingMonitored(keys: ["MyFirstKey", "MySecondKey"])
Toggle Automatic Calling of NSUbiquitousKeyValueStore's Synchronization method
Zephyr.syncUbiquitousKeyValueStoreOnChange = true // Default Zephyr.syncUbiquitousKeyValueStoreOnChange = false // Turns off instantaneous synchronization
Zephyr.debugEnabled = true // Must be called before sync(_:) Zephyr.sync()
Please ignore the Sample App as I did not add any demo code in the Sample App. It's only in this repo to add support for Carthage.
