Referencing an external application for the run action executable

Current Behavior

When setting the executable of a run action to an external application (by inserting a path), XCodeGen does not recognize this and the executable of the created project is still set to None.

For instance, I want to create a plugin template for an existing application. For debugging, this application provides a launch argument that loads the plugin, therefore I want to set the executable to the app:

schemes:
  ExampleScheme:
    run:
      executable: /Applications/Example.app

Possible Solution

This https://github.com/tuist/XcodeProj/pull/521 PR added PathRunnable class to LaunchAction to the XcodeProj repo.

Either template generation could distinguish between paths and target names in the executable setting and create a runnable path or a buildable reference, respectively, or another option for adding a path could be added to the run action.

XcodeGen Version: 2.23.1

Start with the run action executable handling in XcodeGen and review the referenced XcodeProj PathRunnable change. Verify how path values are distinguished from target names, then confirm that generating the example scheme produces a project whose executable points to the external application.
