There isn't really an autoformat option in Xcode.

There is an option ^I (Control-I) to re-indent the code, which will re-align the code according to the tab width set in your preferences, but that's about as far as it goes.

You might have better luck with a text editor like TextMate? I don't know for certain, but I know it supports Objective-C and has some macros, there may be a reformat option?

    For more control of the code formatting, you can try uncrustify: http://uncrustify.sourceforge.net/ – Rob Keniger Feb 11 '10 at 09:31

    I keep forgetting this every time I don't use XCode for some months. And then I search again and always return to this thread. Thanks for the n-th time! :D – ecth Nov 18 '14 at 09:45

Yes Xcode 4 has an autoformat feature.

Try following:

  1. Select text. CMD+A.
  2. Press CTRL+I .

One trick is to select the code (either "select all" or just the section you want to re-format) - then cut, then paste it back. This triggers the automatic code formatting in the Xcode editor.

    @Joe: oh dear - it works in Xcode 2.x and 3.x - you might want to file a bug report at http://bugreporter.apple.com – Paul R May 11 '11 at 13:48
  • @FearlessFuture: if it’s a large block of code you have to do it explicitly - there’s a menu item for doing this in recent versions of Xode so the above trick is somewhat redundant these days anyway. – Paul R Apr 15 '19 at 16:31

ctrl + I will auto format the code you're selecting

ClangFormat-Xcode is an Xcode plugin available in Alcatraz. This is a nice code format tool.

I found that the Copy & Paste method (Cmd-A then Cmd-C then Cmd-V) worked in XCode 4 and was the method I used whilst I was waiting for google to display the results (Mac was going slow!)

To change, go to xCode => Preferences => Text Editing => Indentation => Automatically indent based on syntax.

Format on Save

For anyone wanting to format on save this is what I did. It's a bit janky but it works well. ⤵

  1. To get started pick out a formatter for Xcode. I'd recommend SwiftFormat but here's a list of a bunch of them and other handy extensions.
  2. Once you have a formatter picked out assign it a hotkey in Xcode that's not taken such as CMD + ~
  3. Then download a shortcut mapper such as BetterTouchTool.
  4. In your shortcut mapper simply setup CMD + S for Xcode and set it to actually use your shortcut you set for your fomatter. Like this ⤵ enter image description here
