Implementing the Map screen
When you launch the app, the Explore screen is displayed. Tapping the Map button in the tab bar makes the Map screen appear, but it is blank. To make the Map screen display a map, you’ll add a map view to the view in the view controller scene for the Map screen. Follow these steps:
- Select the view controller scene for the Map screen:
