Issue Description:

I am running into a SourceKit crash in Xcode 11.4 with code that I’ve been able to narrow down into the following snippet:

It is always reproducable, e.g. in Xcode Playgrounds, see the attachment.

#if os(iOS)
@objc protocol HasWindow: AnyObject {
    var window: AnyObject { get }
}
#endif
