High Level Documentation

Where did the high level documentation, such as Introductions and Guides get off to?


For example, where do I find, on the Apple Developer Documentation site these two guides or the replacements for them:


https://developer.apple.com/library/archive/documentation/Miscellaneous/Conceptual/MetalProgrammingGuide/Introduction/Introduction.html


https://developer.apple.com/library/archive/documentation/Cocoa/Conceptual/UserDefaults/Introduction/Introduction.html


There doesn't seem to be anything on what I'll call the "Current Site" but the low level, raw API documentation like https://developer.apple.com/documentation/metal?language=objc

There appears to be no up-to-date high level documentation any more other than the Archive of unmaintained and out of date documentation which was actually useful.

Once upon a time Mac applications came with awesome Help Books - try finding any up-to-date documentation of that topic now! You have less than a snowball's chance in hell. Result: most developers now provide a PDF file instead or a link to a website than can disappear and may not be found in the Internet Archive. Sad.
