zoneBusy
An error that occurs when the server is too busy to handle the record zone operation.
Declaration
static var zoneBusy: CKError.Code { get }Discussion
Try the operation again in a few seconds. If you encounter this error again, increase the delay time exponentially for each subsequent retry to minimize server contention for the zone.
Check for a CKErrorRetryAfterKey key in the userInfo dictionary of any CloudKit error that you receive. Use the value of this key as the number of seconds to wait before retrying the operation.
