How to add file to all targets in Xcode when you have many targets?

Question

I have a project with over 50 targets and growing and it is becoming cumbersome to add files to all targets because it takes a long time to select each target.

I am aware of multiple methods to add a file to multiple targets but they all involve checking a box for each target. (for those looking for that: How to add .plist file to all targets in XCode?)

What I'm looking for is an alternative method or script that can be used to add a file or set of files to all targets in the project without selecting them one by one. Anyone know of a trick?

Answer 1

Here is a link to GitHub repo. In the example project I have three targets, added file only in first target. When you run ruby ./addfile.rb from project's directory, the script will add img.jpg resource into two other targets (projex2, projex3). You need to install xcodeproj ruby gem before running the script. You should run sudo gem install xcodeproj in terminal.
