Is an "AssociatedObject" property wrapper impossible?

[cukr]

@AlexanderM

Property wrappers don't give a way to access self , and I couldn't figure out any hacks to try to smuggle it in. Is this code just impossible to properly implement?

How to get self of parent in @propertyWrapper?

Officially? You cannot. Unofficially? You can use underscored subscript - check out this test in the swift repo Underscored stuff isn't official, there are no guarantees and can be removed at any time.
