Testing our code

Plug in an iOS device to your Mac, and compile and debug the app. You should be presented with a lovely blank white screen. Because we're using CoreLocation, you need to give permission for the app to use your location. It's important that you agree to this:

Location permission dialog

Now, open the companion app on your Mac and choose the beacon profile named Chapter 1 : Default Beacon from the list on the left-hand side and then click on the power button, as shown in the following screenshot:

Using your Mac to broadcast your first iBeacon

What you've just simulated is your device entering a region. If this was a real scenario, the beacon would have been running all along and your device would come into range because you walk towards the beacon, but the companion app serves just as well in this instance.

If all was successful, you should see the following screenshot:

Successfully entered the region

Finally, test exiting the region by turning the beacon profile off in the companion OS X app. It may take up to 30 seconds for the app to register that you've left the region. Once the event fires, you should see the following screenshot:

Successfully exited the region


The reason for the delay is that the didExitRegion method is meant for tidying up resources after ranging beacons, which we'll cover in the later chapters. Apple's implementation includes a delay to ensure the event isn't fired when the Bluetooth signal may be subject to interference.
