DVTSourceControlGitXPCClient crash on Xcode 14

Question

Since a few days ago, I've been experiencing a repetitive crash on Xcode every 3-8 minutes.

The only tangible thing I can find in the crash logs is that it always shows:

Crashed Thread: Dispatch queue: DVTSourceControlGitXPCClient :: Proxy Completion Queue

It seems to be Source Control related, but I wonder how?

I will add everything related to my current project in case it is relevant:

• Xcode 14.2 (14C18)
• Using Source Control with GitHub
• Swift targets iOS and macOS
• SPM

It seems like some folks are experiencing a similar issue, as seen on the Developer Forums

Any leads as to why or how to solve it?

Answer 1

After some struggling I decided to check how was git doing, directly from the Terminal.

It turns out there were some things that didn't make sense, specifically a file I deleted from my project but then added again, was showing as modified, even though I had already committed all changes for that file a few days ago; but I had done it directly from Xcode Source Control.

From the Terminal, I staged all changes and committed them. Since then Xcode hasn't crashed for a few hours yet.

My limited understanding of the problem points out that Xcode had issues staging those changes I made a few days ago, and since then the repository has not been in a "healthy state"; Xcode tries somehow to understand the state of the repository but after a while, it just crashes.

Common scenarios where this could have happened:

• A file was deleted
• A file was renamed, specially with case-sensitive renames, for example from MyViewcontroller.swift to MyViewController.swift

The solution for me was to just put it back in a "healthy state", aka make a commit directly from the Terminal.

Example

From the Terminal

# navigate to the directory of your repository
$ cd /someFolder/myProjectApp

$ git status
# check that you get "nothing to commit"
# or if there are changes they should make sense

# if some changes do not make sense
# try staging and committing everything
# example:
$ git add .
$ git commit -m "Cleaning state"
