In this chapter, we expanded our knowledge of the CLLocationManager and CLBeacon classes by determining our device distance from a beacon using the CLBeacon class's proximity and accuracy properties.

In the next chapter, we'll discuss beacon discovery when our app is in the background, and using this knowledge, we'll be building a proximity-based dating app.

Since there's a lot of code in this chapter, you might come across some stumbling blocks; feel free to ask me any questions on Twitter at @craiggilchrist (https://twitter.com/craiggilchrist).
