Core Data: Could not cast value of type 'MyType_MyType_2' to MyType

Question

I have an Objective-C model class MyType. This class is used in Swift code:

NSEntityDescription.insertNewObjectForEntit         


        

Answer 1

just try this:

@objc(MyType)
public class MyType: NSManagedObject {
    // your class
}

instead of this:

class MyType: NSManagedObject {
    // your class
}
