Force Xcode to ensure code folding?

Question

I am testing OS X. I have a source file that is heavy with macros and preprocessor tests. I am trying to collapse the code, so I can determine why a particular character is not defined.

According to Apple Foldable and Deploying Source Code , I have to do this through the focus ribbon. This does not work - there is no tape, and the editor does not respond to requests from the menu.

According to Stack Override resetting code to default (and others, for example How to minimize all methods in Xcode? ), I can use hotkeys for this. This also does not work - the editor also ignores them.

I don't have #pragma marks or #regions , so can you set code areas in Xcode? not applicable.

Code warehousing was disabled in Xcode 9 beta 1, which is now working, in Xcode 9 Beta5 according to the beta note: Solved in Xcode 9 beta 5 - IDE

Here's how:

• Press and hold the ⌘ (command) button on the keyboard and move / hover your mouse over any (start or end) curly braces. It will automatically highlight the block area.
• Hold (hold) ⌘ (command) and press the highlighted area. This will allow you to quickly open the menu window with the Fold option.
• Select Fold from the menu list. It will add your code and display 3 points, folding / closing the entire block.
• Now, to expand your code block again, release the ⌘ (command) button and click on 3 points, folding the block.
