>> Your error looks correct to me -- "self" in a classmethod is not an instance, but the class itself. And while instances of X implement "Delegate", the Class does not.

Adding an explicit cast would be the simplest way to allow your code to continue being broken in the same way it was previously broken.  E.g.

  // TODO: fix the types here -- self is _not_ actually an id<Delegate>!
  y.d = static_cast<id<Delegate>>(self);
