Hi,
App getting crash with following error. *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Cannot remove an observer <PBJVision 0x17ea24d0> for the key path "currentDevice.flashAvailable" from <PBJVision 0x17ea24d0>, most likely because the value for the key "currentDevice" has changed without an appropriate KVO notification being sent. Check the KVO-compliance of the PBJVision class.'
