The popup asking me to authorize the collection of location data only presented itself once. Thereafter, when I ran my app and clicked on my Current Location button in the MapView, I wasn’t asked to authorize the collection of location information. Here’s the fix:
Click on the Simulator. Look up at the menu bar at the top of the window, then repeatedly click on Hardware>Home until you arrive at the Home screen in the Simulator window, which contains several icons including a Settings Icon(looks like some gears).
Click on the Settings Icon, then General>Reset and click on Reset Location & Privacy.
Run your app, and it will ask you for authorization again.
