I import the logged in user's data from server into a Core Data Entity called "User". I also keep a reference of this specific User object onto my AppDelegate (as a property) so I can access it elsewhere in my app. The problem I am facing is, when I push another view controller and try to access appdelegate.loggedInUser.id , I see that "id" is nil. Debugger shows this for the object : 

```
$24 = 0x0b28ad30 <User: 0xb28ad30> (entity: User; id: 0xb261160 <x-coredata:///User/tC48E8991-B8A6-4E68-9112-93F9F21DB5382> ; data: <fault>)

```

My understanding was that the Core Data framework would fire the fault the moment I try to access one of the properties of this object. I am confused as to why me accessing the "id" property of the user is not firing a fault in this case?

**EDIT**:

This is how create and use the loggedInUser object : 

```
//method to get bgContext 
+(NSManagedObjectContext *)getContextOnBgWithParentSetToMainMOC
{
  NSManagedObjectContext *tmpContext = [[NSManagedObjectContext alloc] initWithConcurrencyType:NSPrivateQueueConcurrencyType];
  [tmpContext setParentContext:[Utils getAppDelegate].managedObjectContext];
  return tmpContext;
}

//in App Delegate
NSManagedObjectContext *bgContext = [NSManagedObjectContext getContextOnBgWithParentSetToMainMOC];
   self.loggedInUser = [User importFromObject:loggedInUserData inContext:bgContext completionBlock:^(NSManagedObjectContext *theContext, NSManagedObject *theManagedObjectWithValuesImported) {}];

//In User.m file
+ (User *)importFromObject:(NSDictionary *)dictionary inContext:(NSManagedObjectContext *)context completionBlock:(TemporaryContextImportReturnBlock)block {

  if ( !context ){
    context = [NSManagedObjectContext getContextOnBgWithParentSetToMainMOC];
  }

  NSManagedObjectContext *localContext = context;
    User *newUserEntity = [NSEntityDescription insertNewObjectForEntityForName:@"User" inManagedObjectContext:localContext];
    NSArray *emailsArray = [dictionary objectForKey:@"emails"];
    NSString *emailsString = @"";
    if ([emailsArray count] > 0){
      emailsString = [emailsArray componentsJoinedByString:@","];
    }
    newUserEntity.emails = emailsString;
    newUserEntity.id = [dictionary objectForKey:@"id"];
    newUserEntity.n = [dictionary nonNullObjectForKey:@"n"];
  return newUserEntity;
}

//Access in one of the view controllers
    User *loggedInUser = [Utils getAppDelegate].loggedInUser;
//    loggedInUser.id /*nil*/

```
