Documentation for Xcode Source Editor Extension

Question

I'm looking for some documentation of the new Xcode Source Editor Extensions in Xcode 8.

As far as I can see there is only the "documentation" found in the header file for XcodeKit. Would be great to get something that's more detailed and more official.

Answer 1

Very preliminary XcodeKit reference documentation is now available.

Our WWDC 2016 presentation introducing Xcode Source Editor Extensions remains the best walkthrough.

The very shortest version, however, is: Because App Extensions need to be embedded in an application, you need to first create a new macOS Cocoa Application, and then add a new Xcode Source Editor Extension to that application. Then the XcodeKit reference should help some in implementing that.

Answer 2

Not really a documentation but a good reference also https://developer.apple.com/videos/play/wwdc2016/414/
