I have two Xcodes versions installed
4.2. And the former one was the default one.
This wasn’t a big deal unless I tried to open a project in Finder which caused
Xcode 3.2.4 to pop up.
Xcode 4 is a bit tricky:
- CTRL-click on a project so context menu pops up, select Open with
- File selection dialog pops up.
- Press Shift-CMD-G - Goto Filder dialog pops up.
/Developer/Applications/and press return to goto the folder
Xcode.appand check Always open with to make it default
Xcode 3 default, repeat same steps but use
/Developer-old/Applications/ for step 4.
