Re: [swift-evolution] [Pitch] allow non-nominal type extension

It’s also the same as:

typealias CombinedProtocol = TrackCountProvider & PublishDateProvier

extension CombinedProtocol { } 

I, too, find the distinction largely pointless, but I’m not a language designer.

[swift-evolution] [Pitch] allow non-nominal type extension

2016-10-20 Thread Cao Jiannan via swift-evolution 
It is just same as current grammar:

extension TrackCountProvider where Self : PublishDateProvider { ... }

with a more logical format

extension TrackCountProvider & PublishDateProvider { ... }

e.g.

extension TrackCountProvider & PublishDateProvider {
var trackCountAndPublishDateText: String {
var infos: [String] = []

if let trackCount = trackCount  {
infos.append("\(trackCount)")
}

if let publishDateText = publishDate?.text {
infos.append(publishDateText)
}

return infos.joined(separator: seperator)
}
}
