This is where you set the permissions you want your app to have. If it has a feature where the user can take a photo, you need camera permissions. If it uses location services eg it tries to detect where the user is, it will need Location Services and GPS. If it informs the user of events eg reminds of an appointment then it will need local notifications. If you don't set these permissions here, the app will not work correctly. However, bear in mind if you just check everything in case the app needs it Apple will probably reject your app when reviewing it for the app store. Another thing to note is that your selections will affect your apps visibility in the App Store. If it requires GPS it will only appear for devices that support GPS. You do need to set only the permissions your app needs.
