How to get smart tabs (“indent with tabs, align with spaces”) behavior in Xcode?

Question

I used to use tabs for indentation and spaces for alignment. Like so (arrows show tabs and dots show spaces).

In QtCreator you can set such coding style in standard preferences. I can't find the way to achieve the same goal in Xcode. Could you please tell me if it is possible? May be there is a plugin for that?

UPDATE: Here is how it can be achieved in QtCreator:

P.S. Please, don't try to persuade me that using spaces only/tabs only is better, otherwise this question will turn into another holywar :)

Once more about what I'm trying to achieve: Indent with tabs, align with spaces. Vim Tips Wiki.

UPDATE 2: I've just submitted an Apple Radar bug-report (enhancement) rdar://22285639. Here it is on the open radar.

UPDATE 3: I received an answer from Apple. My bug is a duplicate of rdar://8165023.

Answer 1

In Xcode > Preferences (⌘,):

If I understand your question correctly, this should do it for you.

Answer 2

If you want to remap the standard Xcode's ⌘+[ to TAB, you can do the following:

1. Install a program called "Karabiner".

2. Go to Preferences ~> "Misc and Uninstall"

3. In "Custom Setting" section click on the "Open private.xml" button

4. Open the file and replace its content with the following code:

   <?xml version="1.0"?> 
   <root>
       <item>
           <name>Tab instead of Command+[</name>
           <identifier>private.swap_tab_and_cmnd+[</identifier>
           <autogen>
               __KeyToKey__
               KeyCode::TAB, ModifierFlag::NONE,
               KeyCode::BRACKET_RIGHT, ModifierFlag::COMMAND_L | ModifierFlag::NONE
           </autogen>
       </item> 
   </root>
   

5. Go to Preferences ~> "Change Key" ~> click on "Reload XML" button

6. Put a tick in the checkbox which is called "Tab instead of Command+["

7. Enjoy

PS: Please note that this setting works globally on your machine, not just in Xcode. However, I am sure that google might help you to find a solution how to customize it even further, applying the changes only to Xcode.
