I used to be able to use three finger scroll-up to switch between source/header. Since upgrading to Lion, I it just does a regular scroll. Is there any way to get that fea
Looks like you can now switch using a left and right two finger swipe. Seems pretty buggy though, given that this also scrolls the screen. It also switches the butler from automatic to manual mode.
I'm starting to hate the combination of Lion and Xcode.
Given apple took this away (hopefully just for now) the only way I can think of to get this working again would be to install BetterTouchTool[1] and bind the keyboard control - control-cmd-up, ctrl-cmd-down - to the three finger motion. You'd also have to switch the default three finger motion in sys prefs to use four fingers for mission control.

If you're using an Apple magic trackpad, you'll also need to edit
com.apple.driver.AppleBluetoothMultitouch.trackpad.plist
which can be found in the
/Users/YOURUSERNAME/Library/Preferences
directory. Open it and change the threeFingerVertSwipeGesture key to a 1.
Save the *.plist
I also changed both my App Expose and Mission Control swipes to be 4 finder swipes instead of Lion's default 3 finger swipe.
Restart your computer
Hope that helps!
Apple fixed the issue in Xcode 4.2. So, upgrade your versions.
Have fun coding and mind the occasional crash.
As found in internet:
defaults -currentHost write -g "com.apple.trackpad.threeFingerVertSwipeGesture" -int 1
Logout and Login again
The answer from icnivad was so very close to working for me. With one additional step.
From your terminal:
Change to appropriate directory (note, if your Library dir is hidden, in the terminal just type the following: chflags nohidden ~/Library )
1. cd /Users/YOURUSERNAME/Library/Preferences/ByHost
List files so you can see the .GlobalPreferences.XXXX-XXXX-XXXX-XXXX.plist
2. ls -lah
Open that plist file in xcode
3. open -a /Developer/Applications/Xcode.app ".GlobalPreferences.XXXX-XXXX-XXXX-XXXX.plist"
Set value to 1 for the key "com.apple.trackpad.threeFingerVertSwipeGesture"
Save the plist file
Restart machine
THEN
Make sure the "Three finger drag" System Preference is disabled. This seems to take precedence and stop the Xcode gesture from working.
