Hi Mario,
You’re right that this part of the proposal was not fully implemented.
Computing the common ancestor of two superclasses is a little tricky here
because it would force us to resolve the superclass type of a class when
realizing a subclass existential. This would introduce circular
Hi everyone,
I noticed strange behaviour of the Swift 4.0.3 compiler regarding class and
subtype existentials.
According to the proposal SE-0156
(https://github.com/apple/swift-evolution/blob/master/proposals/0156-subclass-existentials.md),
multiple class types in protocol compositions should
