问题
I've just updated to Xcode 7 general release and ive tried committing files. Its failing however, and im getting the following message;
Ive seen this question but the secondary response is different in the OP question: Xcode and Git Source Control : “The working copy XXXXX failed to commit files”
Whats the 'helper application' that it is looking for and whats the solution? Migrating to Xcode 7 and iOS9 is becoming a headache :( I commit my files by going to 'Source Control' -> 'Commit'
回答1:
Turns out the “helper application” is in fact Git. For some reason Xcode 7 is eager to associate you (the committer) with a name and an email address.
To fix it, on the command line, type the following:
xcrun git config --global user.email you@yourdomain.com
xcrun git config --global user.name "Your Name Here"

If the above mentioned solutions don't work, try this one:
Add changes once with a git command. Use terminal and change to your working directory (that contains a /.git folder) and execute:
git commit -a -m "Commit title here"
After that commit via Xcode should work again.

The above solution did not work for me. I am running on Xcode 8 (8C1002) and I have close to 4500 files to commit at once (adding the sources of a library to my project).
The only way I can make it working (without the error message) is by committing smaller number of files multiple times instead of all at once.

This happens to me when I add new image assets. The "fix" is to go to File > Save BEFORE you do a Git Commit. Then the Commit works Fine.
回答5:
I had the same problem.
This fixed my problem: Quit Xcode(using CMD+Q) & run it again.
