Declaration
var subscriptionsToSave: [CKSubscription]? { get set }Discussion
This property contains the subscriptions that you want to save. Its initial value is the array that you pass to the init(subscriptionsToSave:subscriptionIDsToDelete:) method. Modify this property as necessary before you execute the operation or submit it to a queue. After CloudKit saves the subscriptions, it begins generating push notifications according to their criteria.
