Xcode 9 expand/collapse braces/brackets {} side bar missing

Concurring with comment by @strangetimes, I submitted to Apple Bug Reporter the following, in the new SUGGESTION format. Please feel free to pile on to Apple with your own:

35237858 : Code Folding in Xcode 9.1 Only does Entire Functions/Methods

UPDATE, A YEAR LATER…

This is fixed in Xcode 10. Code folding is back. Thanks to all those who piled on to the bug report or whatever.

The new, improved code folding in Xcode 9 or 9.1 seems to only work on an entire function or method. (I'm working in Objective-C today.) This is not very useful. You know, functions or methods are only one curly bracket deep. It is easy to eyeball them. Where I need code folding is for long control flow blocks – if, else, switch, do, while, or just loose blocks. Please bring it back so I can use code folding as it worked in Xcode 8.

The ribbon thing, although I thought it was good, others didn't – I can live without it. But code folding needs to work on all curly-bracket code blocks please.


Updates in Xcode 10:

Xcode 10 has increased support for code folding, including:

  1. A new code folding ribbon showing all of the multi-line foldable blocks of code in the editor
  2. A new style for folded code in the editor that allows you to edit lines with folded code
  3. Support for folding any block of code enclosed in curly braces
  4. Support for folding blocks of code from the folding ribbon, from structured selection, or from the

Menubar ► Editor ► Code Folding ► Fold menu item

Xcode 9

Code folding was disabled in Xcode 9 beta 1, which is working now, in Xcode 9 Beta5 according to beta release note: Resolved in Xcode 9 beta 5 – IDE

Here is how:

  1. Press and hold (command) button in keyboard and move/hover mouse cursor on any (start or end) braces. It will automatically highlight, block area.
  2. Keep (hold) (command) button in pressed condition and click on highlighted area. It will enable quick menu popover window with Fold option.
  3. Select Fold from menu list. It will fold your code and shows 3 dots, folding/covering entire block.
  4. Now, to again unfold your code block, release (command) button and click on 3 dots folding a block.
