didRangeBeacons returns macAddress null

I have integrated iBeacons(EstimoteSDK) in my project.
when i try to run my app didRangeBeacons method returns macAddress null at same time cellForRowAtIndexPath method returns macAddress correctly.

Strange error :(

Hey there,

MAC address is only available when doing "startEstimoteBeaconsDiscoveryForRegion" and not when doing ranging. For a full list of which ESTBeacon properties are available under what circumstances, feel free to check out our SDK reference documentation:
