Swift: Crashing When Adding Attribute (Core Data)

Hi, My app is crashing when updating by Xcode or Test Flight for an existing app.

I added an attribute, but migration and mapping is turned on in the appDelegate.

Is this a swift issue? Or am i missing something?

(Sorry pics weren’t formatted right on the forum image code.

I Did make a new CoreData Model and based it off the previous one (previous one didn’t have the added attribute)


From App Delegate
