Post-Install of Cocoapod get main project directly

In creating a CocoaPod Podspec for a vendored_framework I need to install a shell script to be run after all other build_phases in the main project. The only way I have found to do this is by groping the directory for the .xcodeproj file from the Podfile.

post_install do |installer|
  project_name = Dir.glob("*.xcodeproj").first
  project = Xcodeproj::Project.open(project_name)
  project.targets.each do |target|
    inject_shell_script_build_phase(target)
  end
  project.save
end

This seems ridiculous given that pod install or pod update is running and clearly has this information already. Is there a way to get the project reference directly without having to glob or hardcode the project filename?

Solution

https://guides.cocoapods.org/syntax/podfile.html

There is installer.pods_project

post_install do |installer|
  project = installer.pods_project

  project.targets.each do |target|
    inject_shell_script_build_phase(target)
  end

  project.save
end

https://www.rubydoc.info/gems/cocoapods/Pod/Installer#pods_project-instance_method https://www.rubydoc.info/gems/cocoapods/Pod/Project inherits from https://www.rubydoc.info/gems/xcodeproj/Xcodeproj/Project

to iterate the *.xcodeproj you can do

post_install do |installer|
  installer.aggregate_targets.each do |target|
    user_project = target.user_project

    puts "#{user_project.path}"
  end
end
