subscriptionIDs
The IDs of the subscriptions to fetch.
Declaration
var subscriptionIDs: [CKSubscription.ID]? { get set }Discussion
Use this property to view or change the IDs of the subscriptions to fetch. Each element of the array is a string that represents the ID of a subscription. If you intend to modify this property’s value, do so before you execute the operation or submit it to a queue.
If you use the fetchAllSubscriptionsOperation() method to create the operation, CloudKit ignores this property’s value and sets it to nil.
