Modify the IOS app from the zip file attached
1. Turn off the user’s permission to access location for the App (in the Simulator, go to Settings > Privacy > Location). Run the app again and observe what happens. Is this appropriate behavior? How could it be improved?
2. What would happen if the code in Listing 13.10 was placed in viewDidLoad instead of viewWillAppear? (Check MapPoint.swift)
3. Change the text displayed on the pin to include the City for the contact.
4. Change the cell layout to use the other two styles.
5. Expand the settings screen to allow for specifying two sort fields. Then have the sorting be done by first one and then the other field.
