RLMNotificationToken

Objective-C

@interface RLMNotificationToken : NSObject

Swift

@_nonSendable(_assumed) class RLMNotificationToken : NSObject, @unchecked Sendable

A token which is returned from methods which subscribe to changes to a Realm.

Change subscriptions in Realm return an RLMNotificationToken instance, which can be used to unsubscribe from the changes. You must store a strong reference to the token for as long as you want to continue to receive notifications. When you wish to stop, call the -invalidate method. Notifications are also stopped if the token is deallocated.
