We will now set up the project to build for an iOS device:

1. First, be sure to save the scene (File | Save Scenes) and project (File | Save Project). If prompted for a scene name choose what you want, such as PurpleFinch.
2. Go into File | Build Settings and make sure the scene is the only one listed in Scenes In Build (press Add Open Scenes).
3. In Build Settings Platform, make sure iOS is the target platform (select iOS and press Switch Platform).
4. Now go to Player Settings and look at the Inspector on the right.
5. Under Other Settings the Package Name must be set to a unique identifier, in the format com.Company.ProductName such as com.PurpleFinch.BusinessCard.
6. In the Configuration section, fill in the Camera Usage Description with something like augmented reality to ask the user permission to use the camera.
7. Again, Save Scene and Save Project.
