Storing a PFUser object in a PFUser key crashes

Question

I tried to figure out what I was doing wrong all day, but I absolutely do not know why the application always crashes.

The situation is as follows:

I created a simple project with all the necessary libraries and frameworks. I created several Parse users with the following instance method:

[self signUpUserWithName:@"nico" withPassword:@"123"];
[self signUpUserWithName:@"gabriel" withPassword:@"123"];
[self signUpUserWithName:@"bruno" withPassword:@"123"];

Here you can see the implementation of the method:

-(void)signUpUserWithName:(NSString *)username withPassword:(NSString *)password{

    PFUser* user = [PFUser user];
    user.password = password;
    user.username = username;



    [user signUpInBackgroundWithBlock:^(BOOL succeeded, NSError *error) {
        if(!error){
            NSLog(@"User created.");
        }
        else{
            NSLog(@"User couldn't be created.");
        }
    }];

}

It works as expected, users are created, and everything is in order. Now I register the user and create a PFUser object for the current user using the following code:

  [PFUser logInWithUsername:@"user1" password:@"123"];


    //Fetching Current User
    PFUser* currentUser = [PFUser currentUser];
    if ([currentUser isAuthenticated]){
        NSLog(@"Authenticated");
    }
    else{
        NSLog(@"Not Authenticated");
    }

, . , currentUser, . , , " " ( ).

PFQuery* friendQuery = [PFUser query];
    [friendQuery whereKey:@"username" equalTo:@"user2"];
    [friendQuery getFirstObjectInBackgroundWithBlock:^(PFObject *object, NSError *error) {
        if(!error){
            NSLog(@"%@",object);

            currentUser[@"myfriends"] = object;
            [currentUser save];

        }
        else{
            NSLog(@"Failed getting User Object.");

        }
    }];
