How to view just the public API "header" of a Swift file?

Question

I am now programming in Swift to edit the file/class Chicken.swift and I need to refer to the public api for Food.swift. Because the Chicken wants to eat Food.

So I click on Food.swift so I can RTFM. But instead of just getting the public api part that I am interested in, I get all the private crap and implementation details.

This is inefficient. Back in C/Objective-C/C++, I would just click on the .h file to get only the details I need.

Where does such information now exist for Swift development in XCode?

Answer 1

Answer 2

Shortcut for this is

CMD + CTRL + arrow up
