  • SR-6480 The self value in a class method should always have DynamicSelfType

Issue Description:

Here is a rather strange behaviour, self cannot be used where Self is needed:

final class A {
  func act() {}

  func check() {
    func foo(s: Self) {}
    foo(s: self)
    Self.act(self)
  }
}

error:

file.swift:40:12: error: cannot convert value of type 'A' to expected argument type 'Self'
    foo(s: self)
           ^
                as! Self
file.swift:41:14: error: cannot convert value of type 'A' to expected argument type 'Self'
    Self.act(self)
             ^
                  as! Self
