  • SR-6000 Let protocols inherit from class types

Issue Description:

As mentioned in https://bugs.swift.org/browse/SR-6002 Swift trunk development toolchain for September 26, 2017 fails to compile a working project.

The project is https://github.com/guidomb/Portal. To lock down a discussion on a working version of Portal I would suggest using this https://github.com/guidomb/Portal/tree/10af72b428b8122b93435ea08750a6de2f365c84 commit which is known to compile with Xcode 9 stable Swift toolchain.

While I was trying to compile Portal using Swift trunk development toolchain for September 26, 2017 I got a compiler abort trap while trying to compile file

https://github.com/guidomb/Portal/blob/10af72b428b8122b93435ea08750a6de2f365c84/Portal/View/UIKit/Renderers/MessageProducer.swift

The reported error

Assertion failed: (witnessSelfProtocol == getProtocol() && "Default witnesses must have an abstract Self parameter " "constrained to their protocol."), function verify, file /Users/buildnode/jenkins/workspace/oss-swift-package-osx/swift/lib/SIL/SILVerifier.cpp, line 4484.

This isn't supported yet: "protocol MessageProducer where Self : UIControl"

I should fix it soon...

What is it doing in Xcode 9 that we're going to be forced to emulate? :-(

It respects the superclass constraint in some cases and doesn't in others I imagine. I'm not going to emulate it since it's not a useful behavior.
