bloomberg / Xcdiff

xcdiff is an extensible tool that finds differences between two .xcodeproj project files. It can be thought of as git diff for .xcodeproj files, which can be used directly from the command line as well as a library supporting your own set of tools.

How to use xcdiff

Running the command xcdiff in your project directory will search for two .xcodeproj files in this directory and use all of xcdiff's comparators on the projects (e.g. targets, sources and headers).

You can also specify two particular projects for xcdiff to compare.

xcdiff -p1 OriginalProject.xcodeproj -p2 GeneratedProject.xcodeproj

Here is an example output:

To see a detailed report of differences you can specify the --verbose (-v) option.

xcdiff -p1 OriginalProject.xcodeproj -p2 GeneratedProject.xcodeproj -v

Use Cases

• When adopting project generation (e.g. using tools like XcodeGen or Tuist), comparing the generated xcodeproj files against the original ones can help boost confidence in the migration process.
• Probably a few more we haven't thought of yet!...

Installation

• Install xcdiff and use from the command line.
• Add as a dependency of your macOS project (xcdiff follows the semantic versioning).

Documentation

• Read xcdiff CLI documentation or try xcdiff --help.
• Check out how to use XCDiffCore Framework in your own project.
