iOS Shortcuts App: How can I convert my Workflow to a service app? Back in AppleScript or Apple Automator it is possible to convert workflows to a compiled read-only application. 

Is it possible to hide, compile or convert my iOS Shortcuts workflow to a self-running service, too? So far I don't see any way to lock or prevent changes to my workflow.
This isn’t possible. You would need to compile an app to import and run these “locked” scripts. 

Xcode lets you install your own apps without needing a paid developer account.
