 To observe an object, implement the `ObjectObserver` protocol and specify the `EntityType`:
 ```swift
 class MyViewController: UIViewController, ObjectObserver {
-    func objectMonitor(monitor: ObjectMonitor<MyPersonEntity>, willUpdateObject object: MyPersonEntity) {
+    func objectMonitor(_ monitor: ObjectMonitor<ObjectEntityType>, willUpdateObject object: ObjectEntityType) {
         // ...
     }
     
-    func objectMonitor(monitor: ObjectMonitor<MyPersonEntity>, didUpdateObject object: MyPersonEntity, changedPersistentKeys: Set<KeyPath>) {
+    func objectMonitor(_ monitor: ObjectMonitor<ObjectEntityType>, didUpdateObject object: ObjectEntityType, changedPersistentKeys: Set<KeyPathString>) {
         // ...
     }
