I am struggling a bit with generics in Swift.

I have the following code:

XKNavBar extends from XKBaseWidget

The code in CoreStore 3.1.1 is working, but upgrading to CoreStore 4.2.3 is not.
I guess that might be related the following?

Any idea how to solve this problem?

Thanks.

@RosalieChang You can set the generic type and the actual dynamic type for Into and From separately:

Into<XKBaseWidget>(XKNavBar.self)
From<XKBaseWidget>(XKNavBar.self)
