NSUnknownKeyException for existing and non-mistyped key

Question

I\'m getting the following output:

*** Terminating app due to uncaught exception \'NSUnknownKeyException\', reason:
\'[ setValu         


        

Answer 1

The problem is quite strange (sometimes works, sometimes not), so I would suggest to change the name of the attribute (e.g. booleanStatus) and verify if the problem still persists or not.

Since you have changed the model you need to remove the app and ricreate it. Alternatively you could perform an automatic migration on Core Data. As you prefer.

Hope it helps.
