What is this?

One of the frustrations of working with Xcode together with Git is resolving conflicts in Xcode project files, i.e. the project.pbxproj file.

Kintsugi sets out to solve this exact problem: Automatically resolving Git merge conflicts occurring in .pbxproj files.

The end goal is for the tool to succeed 99.9% of the time, and let you resolve the real conflicts in a convenient way the rest of the time.

Kintsugi (金継ぎ) is the art of repairing broken pottery by mending it with gold. Wikipedia


Kintsugi understands the changes you've made to the .pbxproj file, so it simply resets the conflicts and re-applies those changes to it.

From a technical perspective, Kintsugi heavily relies on Xcodeproj. It uses its diff capability to extract the changes, and uses its project files editing capabilities to apply the changes.

Installing Kintsugi

$ gem install kintsugi

If you prefer to use bundler, add the following line to your Gemfile:

gem 'kintsugi', require: false


When there's a .pbxproj file with Git conflicts, and a 3-way merge is possible, run kintsugi <path_to_pbxproj_file>.

And see the magic happen! :sparkles:

Git merge driver

You can setup Kintsugi to automatically resolve conflicts that occur in pbxproj files when such conflicts occur.

Automatic install

Run kintsugi install-driver. This will install Kintsugi as a merge driver globally. Note that Kintsugi needs to be in your PATH.

❗ Do not install with bundler because the installation might succeed even if Kintsugi is not in PATH.

Manual install

  • Add Kintsugi as driver to Git config file by running the following:
git config "Kintsugi driver" # Or any other name you prefer
git config merge.kintsugi.driver "<path_to_kintsugi> driver %O %A %B %P"

Run git config with --global to add this to the global config file.

  • Add the following line to the .gitattributes file at the root of the repository:

*.pbxproj merge=kintsugi

This will instruct Git to use Kintsugi as a merge driver for .pbxproj files.

See the official docs if you want to set this globally.

All of the alternatives below allow you to generate your Xcode projects based on a spec or manifest. You commit these files to git, and can even remove the .xcodeproj files from git.
