Cannot remove an observer
xuming120 opened this issue · comments
Cannot remove an observer <PBJVision 0x12b2be340> for the key path "currentDevice.torchMode" from <PBJVision 0x12b2be340>, 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.
