objective c - Beacon Crash in IOS 10 -
anyone please fix "beacon crashing in ios10". didrangebeacons delegate method returns beacons array nil , code follows

there number of anecdotal reports of beacon detection problems on ios 10, users reporting setting app deployment target in xcode 9.x resolve issue. see here details:
