I don't believe these rules have a place in the API guidelines, which are meant to address how Swifty APIs should be constructed for consumption.  Style rules are best addressed by in-house style guides. I've personally adopted left-magnetic colons. This follows the Docs team style. The stdlib folk appear to use floating colons for protocol conformance.

As for Xcode, the new code editor extensions provide exactly this kind of functionality.
