Master data cannot generate where clause for predicate (Swift)

I have a Managed Database Object with NSNumber property (stored as Integer 64). I am trying to get an object using a predicate like this:

let request = NSFetchRequest(entityName: "MyEntity")
request.predicate = NSPredicate(format: "pageId == %@", pageId)

and then throws the following runtime error:

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Unable to generate where clause for predicate (pageId == 22205021) (unknown problem)'

where pageId is "22205021" in this case. As far as the suggestions pageId == 22205021

go , it looks ok, which is why I don't understand why it won't work.

Note. I am using Xcode 7 beta 4.

In fact, it turned out to be my mistake - I used a non-existent property for this object in the predicate. "MyEntity" did not contain "pageId" - the best error message would not subside.

pageId

cannot be NSObject when in Swift.

Try it NSPredicate(format: "pageId == %d", pageId)

.



This uses an integer for comparison, not NSNumber.

The code you posted looks correct to me. If the code works in the previous Xcode and no other changes (other than compliance) I would think it might be a reported bug.
