The date and time when the system should deliver the notification.
- iOS 4.0–10.0Deprecated
- Mac Catalyst 13.0–13.0Deprecated
- watchOS 2.0–3.0Deprecated
The fire date is interpreted according to the value specified in the
time property. If the specified value is
nil or is a date in the past, the notification is delivered immediately.
You may specify a value for this property or the
region property but not both. Attempting to schedule a local notification that contains both a region and fire date raises an exception.
