XCode 10.2 git error : Couldn’t communicate with a helper application

Same here... really annoying.

Same for me, it's begining to grate, to be honest.

Has anyone found a solution, any feedback from Apple?

Good news! Xcode 11 Beta fixes this problem

This seems to be the case, indeed!

Thank you.

I have the same problem. Any workaround for current XCode?! I can't use Xcode 11 Beta 😟

Feels like I have to downgrade to previous version.

Still waiting as well for a viable solution as it is a Beta version of Xcode

Still an issue for me. Very annoying and disruptive.

Worst updates by Apple. Crashed git everytime and need to use external tool or command line.

I am surprised this works for me! Apple should provide more error details...

Hi,
it looks like they also solved the problem in the most recently released version : 10.3 (10G8)

EDIT : ... well no, they didn't.

Add Git Author name and email

Can be configured in next places:

- XCode Preferences -> Source Control -> Git

- Repository Git setup

git config user.name "John Doe" 
git config user.email "john@doe.org"

- Global Git setup:

git config --global user.name "John Doe" 
git config --global user.email "john@doe.org"

Only global setup worked for me

I got the same issue, not only Source Control, but manipulating files, or adding new assets to the project shows the same message: Couldn't communicate with helper application.

Recently I found out that folder permissions was the problem.

If anyone facing the same, simply change user (chown) or change permission (chmod) to the project folder to fix this issue.

I am having similar issue.. On the sumulator, I cannot select a file from Icloud drive. I am logged in and see the list of file from ICloud however, when I get the popup error when I select the file..

xCode Version 11.1 (11A1027)

I have tried all solution given on the above replies but it did not solve the issue. This works on the physical device..

Thanks for your help

I was getting this error consistently on my 13" MBP with 8GB of RAM. When I switched to a 15" MBP with 16GB of RAM I have never seen the problem once.
