Xcode 12 documentation not yet available?

I have the released version of Xcode 12, and when I use the help, I am taken to Xcode 11 documentation. (for example https://developer.apple.com/tutorials/swiftui)

Where can I find Xcode 12 specific documentation? Is it a case of not yet having been published?
