| 2016-12-05 19:29:16.988060 Compass[71668:644974] [General] Cannot update for observer <TestObserver 0x600000001060> for the key path "nestedObject.nestedField" from <TestObject 0x600000026ee0>, most likely because the value for the key "nestedObject" has changed without an appropriate KVO notification being sent. Check the KVO-compliance of the TestObject class. | |
