title: Reference to all Swift Protocols?
body: <p>Swift has a notion of <em>class interfaces</em>, called <a href="https://developer.apple.com/library/prerelease/ios/documentation/swift/conceptual/swift_programming_language/Protocols.html" rel="noreferrer">Protocols</a>. However I can't seem to find a full reference of all protocols available in the Swift API. Where can I find a list of all protocols?</p>
