Long story short, I am currently using Bluetooth LE Beacons (iBeacon) to determine if something is in range or not (using didEnterRegion/didExitRegion)
Currently, when those methods get called while the app is backgrounding, I send a local notification using the UserNotification framework. I have been requested to also play an alert overriding the silent switch when didExitRegion is called, similar to how Tile plays sends a notification with audio when the button is played.
If anyone knows how tile works or another way to accomplish this that would be great.
So far, I have attempted to call play() on an AVAudioPlayer with the audio loaded, however play() just returns false from the background. I have also Enabled the Audio backgrounding mode to no avail
