App Sweep

This might be a long shot. I have an existing app that was created with Xcode that App Sweep recognizes when I put it into the trash. I am updating and creating a new build of the app, but now when I put it into the trash, App Sweep doesn't recognize any support files. App Sweep catches other apps on the same workstation. Is there a way to see why that would be the case?

Try enabling debug mode as described here: https://www.noodlesoft.com/kb/hazel-debug-mode/

Next time you throw away the app, check the logs for it to see if there are any messages indicating what happened.
