How to show screen time for iOS?

I know that we can't access the screen time report as raw data, but we can show it on screen. I'm trying to do this, but I am getting these errors:

LaunchServices: store (null) or url (null) was nil: Error Domain=NSOSStatusErrorDomain Code=-54 "process may not map database" UserInfo={NSDebugDescription=process may not map database, _LSLine=72, _LSFunction=_LSServer_GetServerStoreForConnectionWithCompletionHandler} Attempt to map database failed: permission was denied. This attempt will not be retried. Failed to initialize client context with error Error Domain=NSOSStatusErrorDomain Code=-54 "process may not map database" UserInfo={NSDebugDescription=process may not map database, _LSLine=72, _LSFunction=_LSServer_GetServerStoreForConnectionWithCompletionHandler}

I did all set ups. I only have doubts about the set up of a new target, and I didn't do it. Can someone suggest how to fix it, or is it necessary to add a target and, if so, how should it be done?

My code:
