# course

The direction in which the device is traveling, measured in degrees and relative to due north.

```
var course: CLLocationDirection { get }
```

## Discussion

Course values are measured in degrees starting at due north and continue clockwise around the compass. Thus, north is 0 degrees, east is 90 degrees, south is 180 degrees, and so on. Course values may not be available on all devices. A negative value indicates that the course information is invalid.

### Special Considerations

In iOS, this property is declared as `nonatomic`. In macOS, it is declared as `atomic`.
