Xcode 9 commit: Couldn't communicate with helper application

Question

I\'ve recently updated to OSX Sierra (from El Capitan) and to Xcode 9. I removed all compatibility issues (like autolayout issues) and would like to commit to my local gitre

Answer 1

The solution is to add changes once with a git command. Use terminal and navigate to Xcode project folder. If you are in the right folder, this command:

ls -al

will list a .git folder. Then you know you're at the right place. Then execute

git commit -a -m "Commit title here"

After that commit via Xcode should work again.

Answer 2

For me, the Preferences> Source Control > Git > Ignored Files had the Watchkit Extension Complications Controller. Removing it from Ignored Files fixed the problem. Xcode 10.1, Watch OS 4.2.

Answer 3

If you cant change the git name in Xcode, you can change username and email using the terminal:

xcrun git config --global user.name 'new_user_name'
xcrun git config --global user.email 'new@email.com'

And restart Xcode.

Answer 4

the problem that I had was whenever I tried to create source control it show Couldn’t communicate with a helper application. so in Xcode preferences I go to accounts and there I see I was logged out I signed in again and save the project, after closing the project and force quitting Xcode I opened it again and now it works fine for me

Answer 5

For me I had to populate Full Name and Email address in Preferences > Source Control > GIT (tab). They were blank.
