Things You Can't Do
The following is a list of features for which clients have asked that are either physically blocked by the OS or prohibited by Apple.
- Your sound-switch aware app cannot make noise when the screen is locked.
- Reference: Link to developer.apple.com documentation
- Relevant text: "Categories that obey the Ring/Silent switch do not allow audio when the screen is locked."
- Your app cannot "run in the background" while other apps are running.
- In particular, you can't have your app, for example, monitor the GPS and buzz when the user gets close to their destination, unless your app is currently active on the device.
