Where can I find modern Mac OS X Cocoa documentation?

Question

I have been trying to learn how to program using Cocoa on my Mac OS X computer (Running Mac OS version 10.14.2) using Xcode (Running version 10.1)

The challenge I have been having is finding up to date documentation. Most tutorials I can find are for Xcode version 3.x, which seems to not even apply to my version of Xcode, as they mention files that I don't see and tell me to click buttons that do not exist.

Where can I find up to date documentation for Cocoa programming on Mac OS so I can make GUIs for my programs?

I need documentation/tutorials pertaining to things like editing the main.storyboard file, what all the files Xcode automatically makes mean and do, how I can add buttons and make them do various things, taking user input from the keyboard, and Cocoa in general so that I can start making GUIs for my programs.

iOS has overtaken the Mac in popularity among developers. Apple focuses on iOS in their documentation. People writing articles and tutorials focus on iOS too, leaving out Mac developers. This situation makes it difficult for people who want to learn Mac development.

The best source of Mac tutorials right now is Ray Wenderlich's site, but they stopped making Mac tutorials. There's also a Hacking with macOS book that teaches Mac development. I also wrote a couple of Mac articles that might help you: Make a Simple Mac App in Swift and Creating a Document-Based Mac Application Using Swift and Storyboards.
