Being a framework, Core Location contains a variety of components use to work with it. You’ve already encountered a few of them. For instance, you’ve already worked with the CLLocation and the CLLocationCoordinate2D.
CLLocation
The CLLocation contains the geographical location and altitude along with the accuracy of the measurements. It also contains the speed and heading of device in motion. Of course, CL in the CLLocation stands for Core Location so a CLLocation is a Core Location Location. Say that ten times fast.

CLLocationManager
But how do you get a user’s location? For that, you use the CLLocationManager. This object track both large and small changes with a configurable degree of accuracy. It will report heading changes. It will monitor regions and report the range of beacons. Note, we won’t be covering beacons in this course.

Activity Type
The activityType property lets Core Location know how you are using it. For instance, setting it to Fitness lets CoreLocation know the app is doing something like running or cycling, and may pause updates if there is no movement for a significant period time. There are a couple of ways to receive locations. You can either request a single location update or you can receive a constant stream of updates.

CLError
CLError contains lots and lots of different error conditions. A common error is LocationUnknown. This means the device is unable to get the current location. You may encounter this error when Core Location starts up. This is this is the best kind of error in that you may not have to do anything although if continue to receive this error after a period of time, something else may be at play. Let’s play around with locations.
LocationManager.swift
In this demo, we’re going to create our own location manager. We’ll create an object that essentially encapsulates the CLLocationManager. Open up your sample project and press command n to create a new Swift class. Call it LocationManager and save it in the model folder. First import the core Location framework.
