Attempting to Modify Object Outside of Write Transaction

Question

So I have no idea why I am getting this error. The error message is as follows:

* Terminating app due to uncaught exception \'RLMException\', reason: \'Attemptin

Answer 1

The beginWriteTransaction and commitWriteTransaction have to be called on the same realm the object you're modifying is in. Each time you call [RLMRealm defaultRealm], you're getting a new realm. This is not going to be the same realm that's in self.chatSession. To fix this, first confirm that self.chatSession's realm is on the same queue as your queueForWrites (I'm assuming self.chatSession is a RLMObject, of course). Then, just do the following inside the block instead:

[self.chatSession.realm beginWriteTransaction];
self.chatSession.myAlias = alertTextField.text;
[self.chatSession.realm commitWriteTransaction];
