iOS Swift: Crashing When Adding Attribute (Core Data)

[loon3y]

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?


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

Do you have a crash log? The migration is from a database that doesn't have the attribute to one that does have the attribute?

So if you did the exact same thing without the attribute, does it not crash?
