Code Folding changes in Xcode 9/10

Question

I know code folding was missing in the early Beta's of Xcode9 and that it is available to fold entire methods with CMD click.

But in Xcode 8 i was able to fold code in blocks (i.e. individual if statements) via Editor >> Code Folding >> Fold but in Xcode 9 this folds the entire method.

Is there a fix/setting i can change to restore the Xcode 8 functionality?

Updates in Xcode 10

Xcode 10 has increased support for code folding, including:

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

Menubar ► Editor ► Code Folding ► Fold menu item

Look at this snapshot:

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:

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

For easy understanding, look at this snapshot:

It's all keyboard short cuts are also working.

Same options from Xcode Short-cut list:

Menubar ▶ Xcode ▶ Preferences ▶ Key Bindings ▶ "Here is list of code folding short-keys"

Thanks for the detailed response. However as stated in the question I am aware of how to fold entire methods. I am looking to see if the old functionality of folding blocks within methods was still available. — joffd, Oct 06 '17 at 22:17
@joffd Same question for me. I am missing the old feature, the graphical way to do it. — Dominique Vial, Oct 24 '17 at 09:36
Would have been better if given an arrow on left of file to fold, unfold braces blocks — Pankaj, Mar 30 '18 at 07:58

Ya got to be kidding. Who comes up with the idea of dropping code folding after having supported it for decades and it being used all day every day by every developer that's ever developed. Prediction: Due to the advent of retina displays Apple will render every file as a single page even if it drives the font down to 1pt so as to encourage developers to write smaller more sophisticated files written in a brand new language (that will change its syntax dramatically by EOD tomorrow and break your app). – John Erck Nov 20 '17 at 14:09

Xcode 9 is a total Swift re-write. Code-folding will return ;) – Kaisp Nov 20 '17 at 22:11
lol. Ok great. I hope you enjoyed my rant. It's easy to work around and I'm all for progress. – John Erck Nov 21 '17 at 23:09

You can fold individual if statements also in Xcode 9 however it folds the entire if - (else) expression.

Put the cursor somewhere within the block and press ⌥⌘←

that still folds the entire method. – joffd Sep 24 '17 at 06:52
Don't select anything, just put the cursor somewhere between the `if` and the closing `}` of the affected block. See the edited answer. – vadian Sep 24 '17 at 07:01

I am working in objective C would that make a difference? Because no matter wear i put the curser the entire method folds. – joffd Sep 24 '17 at 07:13
It could be that Objective-C behaves differently, I regard it as a bug. In Swift it works as described. – vadian Sep 24 '17 at 07:36

I don't like the change.... – Jerome Sep 29 '17 at 01:31
Why do Apple insist on fixing what isn't broken? – Eatton Nov 10 '17 at 11:44
but in object-c ,it not support – signal Mar 23 '18 at 06:17
