Making your app run on all iOS devices
Before you can make a Mac app from your existing iOS app, you need to modify the user interface to work with iPads. To see what changes will need to be made, you’ll build and run your app on the iPad simulator. Follow these steps:
- Close the simulator if it is running. Choose iPad (9th generation) from the list of simulators in the Scheme menu and run your app:

- The iPad simulator will launch and appear as shown in the following screenshot:

As you can see, the collection view on the Explore screen automatically takes up the whole width of the screen, and the collection view cells are the same size that they were on the iPhone. Even though you can use exactly the same user interface for both iPhone and iPad, it would be better if you could customize it to suit each device.
