The UIBackgroundModes key identifies which background tasks your application supports. Its value is an array that contains one or more strings with the following values:

  • audio – The application plays audible content to the user while in the background.
  • location – The application keeps users informed of their location, even while running in the background.
  • voip – The application provides the ability for the user to make phone calls using an Internet connection.

You can edit the Info.plist file on Xcode. To add a new key, click on the + sign and write:
