No…
I’ve noticed it at the begining and did a test for it:
protocol Disposable {
func destroy()
}
extension Disposable{
func destroy() { }
}
This code works in XCode 7.0 beta but can’t be compiled by Element 8.1/8.2.
So I’m not sure what that bottom line means, but it’s not the same thing described in Swift 2.0 doc.
