Discard all changes in Xcode 4.2

Question

I have an Xcode 4.2 project that uses git as repository. I make some changes in my source code files. In order to discard changes in one file, I do the following:

• Select that file in the Source Tree
• Go to File > Source Control > Discard Changes to discard changes I made in that file

But I want to discard all changes in all files in my project. How to do it?

Answer 1

File > Source Control > Commit (⌥⌘C), on the left pane select the files you want to reset, right click on selection and click Discard Changes in the context menu.

Answer 2

From the command line in the git repository you could do

git co -- .

to reset the files to the HEAD revision.
