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

Getting the same error!

Happens here too after some period of time. Searching says the git email and name fieilds need to be configured, but they are configured and the issue still occurs. Only solution appears to be quitting Xcode which is annoying because it keeps recurring

Same here, using XCode 10.2 (10E125). Things I've tried so far:

- Provinding git e-mail and name fields in XCode Preferences (under Source Control -> Git)

- Commiting and pushing using the commandline and then coming back to XCode

- Hitting Source Control -> Fetch and Refresh Status

None of them helped. Does anyone know a workaround?

Hi,

i have the same issue and i still haven't find a way to help solve it.

i have tried add the git user and the git email to the current git project but without success.

Exactly the same for me, too!

I have the same problem as originally described by PacoLabs. It definitely started after upgrading Xcode to 10.2.

I wonder if it has something to do with our git versions…

Air2: jk$ git --version
git version 2.21.0
Air2: jk$ xcrun git --version
git version 2.20.1 (Apple Git-117)

So you see my "real" git is newer. But that's not the answer because Xcode misbehaved in the same way last week, when my "real" git was older. I updated it the other day using homebrew. Either way, Xcode's git stops working after one or two operations and stays broken until I relaunch Xcode.

It might be helpful for someone whose Xcode git is working to run the above two commands on their Mac and see what they get.

I am having the same issue, and running the commands reports that my git(s) are the exact same version:

$ git --version
git version 2.20.1 (Apple Git-117)

$ xcrun git --version
git version 2.20.1 (Apple Git-117)

Same problem here.

I had no issues until XCode 10.2; since installing 10.2 the Git integration basically started acting weird. Everything is fine until I switch branches (I switch via the Terminal). After that, the integration completely fails and can't be recovered. XCode restart is the only workaround that I was able to find.

Same here. Started with XCode 10.2 and was already present in Xcode 10.2 beta. Also XCode 10.2 periodically loses my GitHub and BitBucket account info.

Obviously, there is a serious bug in Xcode. So I just filed one: 49815119 in https://bugreport.apple.com.

I know, it will soon be closed as a duplicate and maybe fixed in Xcode 11 if we're lucky 😟.

It's a good thing that Xcode's git support has always been so incomplete that we frequently use and still remember the git command line.

I also filled 49612077, 7 days ago (no feedback yet).
So I guess they had 203 042 bugs submitted in 7 days.

Lets see how they will prioritize this ... (I have bugs from 2010 still opened without any feedback)

Getting the same error. This error makes me crazy. Please fix it as soon as posible. It was so handy to use Xcode as diff tool

I had the same problem after upgrading to Xcode 10.2 and setting the name and email from the terminal worked for me:

$ xcrun git config --global user.name "Your name"  
$ xcrun git config --global user.email your.email@example.com

After that i had to restart Xcode and it was working fine again.

Unfortunately, that doesn't solve the problem for me.

Yeah, apparently 10.2.1 does not fix it. Still have this issue. So annoying!

Same here.

Not sure if this is related, but my system generally runs with 1-3GB of swap used. This is with xcode, simulator, debugger, browser. Wondering if the SCM backend is getting killed to free up resources.

I had similar issue with Xcode 10.2.1 and luckily was able to fix it.

In my case there were empty fields Author Name and Author Email under following path.

Xcode - Preferences - Source Control - Git

Try to fill them. Hope your works for someone.

I did it (either using the UI or the command line), but the problem here seems to be unfortunately different.

For information, my bugreport 49612077 has been marked 2 days ago as a duplicate of 47227781 which is in OPEN state.

For me, it does not allow me to fill in values for Author Name and Author Email (or rather, they disappear immediately when closing the view).

Also the "Ignored files" section in the same view shows "Loading...".

The corresponding command line git commands "git config --global user.name" and "git config -global user.email" show normal values.

My bug report was also closed as duplicate of 47227781

You can fill them when XCode starts (while the helper application is reachable).

Once the error appears, they are not displayed anymore (and you cannot set them).

When you'll restart XCode, they will automatically be visible again.

But that does not fixes the problem anyway.

My experience is similar: after launching Xcode, while the git integration is still working, the "Author Name" and "Author Email" fields are set. But once the git integration stops working, those fields are blank.

Same for me with 10.2.1.

Quit and re-launch Xcode seems to be the solution, up to now.

Still annoying though...

Same with me, and the only (for a while) fix is to quit Xcode use terminal, commit, open Xcode and try to change + commit via Xcode. That works. after that Xcode git works at least for a while 😟

Same error here.

And the "Helper Application" error is propagated to the Asset editor too.

I try to create a new Image or Color set and the error appears when I try to rename the resource....

I solved the issue disabling git from the preferences, closing Xcode, re-opening it and re-activating git
