There was a problem hiding this comment. Would be better if you isolate the main logic into a function and call it from the root of the file, then it will be more organized. |

There was a problem hiding this comment. To make it even more beautiful than just isolating into a separate method, you could improve the errors that you raise by using an enum that inherits from Error (or Swift.Error). i.e: enum ScriptError: Error {
case frameworkMissing
case managerNotFound
case failedToStartManager
case failedToQueryPads
// and so on...

There was a problem hiding this comment. I guess you would earn more just using async/await here |

Even though most part of the Script Commands written in Swift in this repository aren't compliant to the "Scripts that require installation of runtimes and dependencies" section of our CONTRIBUTING.md documentation, it is nicer if you add here the information the Script Command requires Swift installed in the user's machine. Otherwise, it would fail.
