#add_packager_script_from(react_project) ⇒ Object

Adds the Start Packager script from the React.xcodeproj under node_modules to the main application target before deleting React.xcodeproj from the Libraries group. Adjusts paths in the script to account for the different project location. If the relevant build phase is not found, a warning is logged, and this step is skipped.
