Instance Property


The accuracy of the proximity value, measured in meters from the beacon.


var accuracy: CLLocationAccuracy { get }


A beacon with a smaller value for accuracy is typically nearer than a beacon with a larger accuracy value.

Use this property to differentiate between beacons with the same proximity value. Do not use it to identify a precise location for the beacon. Accuracy values may fluctuate due to RF interference.

A negative value in this property signifies that the actual accuracy could not be determined.
