Question

If by any chance you have

install! 'cocoapods',
         generate_multiple_pod_projects: true,
         incremental_installation: true

Then, this is the way to do it.

    # generated_projects only returns results if the we run "pod install --clean-install"
    # or install a pod for the first time

    installer.generated_projects.each do |project|
        project.build_configurations.each do |configuration|
            configuration.build_settings["ENABLE_TESTABILITY"] = "YES" 
        end
    end
