My understanding is that allowing protocols to conform to themselves would be a *ton* of work. That’s not to say it’ll never happen, but the current behavior isn’t considered a bug, and I don’t think the feature is likely to happen without a proposal getting accepted on swift-evolution (it’s come up a few times before… IIRC it’s always been shot down because something like “yes, we’d all like it, but we only have so much time before the next release and there’s some much lower-hanging fruit that we should work on first”).
Feel free to start another thread about it… it’d get a +1 from me. I’d almost bet money though that it won’t happen until at least Swift 5 (unless it’s a surprise at WWDC or something).
