Xcode Swift code folding/collapse

Question

I know we can use "Shift + Alt + Cmd + Left" to fold/collapse swift code in Xcode, but can anyone tell me how to fold/collapse for functions only? Not properties? Or any alternative way?

The default folding method does the job, but actually also hide very important information from us......

This is what I wanted!

Answer 1

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

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:

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.

For easy understanding, look at this snapshot:

It's all keyboard short cuts are also working.

Fold                          ⌥ ⌘ ←      option + command + left arrow
Unfold                        ⌥ ⌘ →      option + command + right arrow
Unfold All                    ⌥ U        option + U
Fold Methods & Functions      ⌥ ⌘ ↑      option + command + up arrow
Unfold Methods & Functions    ⌥ ⌘ ↓      option + command + down arrow
Fold Comment Blocks           ⌃ ⇧ ⌘ ↑    control + shift + command + up
Unfold Comment Blocks         ⌃ ⇧ ⌘ ↓    control + shift + command + down
Focus Follows Selection       ⌃ ⌥ ⌘ F    control + option + command + F
Fold All                      ⌘ ⌥ ⇧ ←    command + option + shift + left
Unfold All                    ⌘ ⌥ ⇧ →    command + option + shift + left

Code folding options from Xcode Menu:

Menubar ► Editor ► Code Folding ► "Here is list of code folding options"

Here is ref snapshot:

Same options from Xcode Short-cut list:

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

Answer 2

As of now there is no option to fold only functions in you class, we may expect these features in future release of Xcode. To fold specific function you can use alt + command + left_arrow after placing the cursor in function starting line. Use alt + command + right_arrow for unfold folded function.

Answer 3

Another way to do this would be as below.

• Go to Xcode preferences (command + ,)
• Select the text editing tab
• Check code folding ribbon

Now when you look at your code you should be able to see this :

When you bring your mouse over the folding ribbon you should see a small arrow that can be used to fold code blocks (functions, if-else, loops, etc)

Hope this helps!
