@myobie I merged your pull request. Then, after pulling that change into the iOS app, I thought to myself, when would anyone ever want to listen to those lifecycle events on Mac Catalyst? So, I figured I'd just remove them here inside of SQLite and remove the need for the extra argument and compilation condition inside of our iOS app.
