Frustrated with the tedium of going through all the Xcode project files in a text editor and manually replacing all of the identifiers and filenames when creating a new Quartz Composer Patch, we created a new Xcode template for custom Quartz Composer patches.

To make a Quartz Composer Patch, now all you need to do is:

1. Create a new Xcode project with this template
2. Give the project a name
3. Build the project
4. Move the .plugin file into /Library/Graphics/Patches/ — The template does this for you now.
5. Launch Quartz Composer

And, of course, modify the code, if you want to do something other than nothing.
