Passing information to another viewController

Hi guys, I`m trying to pass information from one viewController to another, but something is wrong.

Here is what I got so far.

FichaTableViewController (when I click one of the rows, it loads the profile page). At the Prepare Segue part, I have this?

if ([segue.identifier isEqualToString:@"showProfile"]) {
        ProfileViewController *profile = segue.destinationViewController;
        profile.objectId = [self.currentDog valueForKey:@"objectId"];
    }

At the top I have a #import ProfileViewController.h

At the ProfileViewController I tried to query the dog`s information using that objectId but it throws me an error.

I have this

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view.
    PFQuery *query = [PFQuery queryWithClassName:@"dog"];
    [query getObjectInBackgroundWithId:self.objectId block:^(PFObject *object, NSError *error) {
        // Do something with the returned PFObject in the gameScore variable.
        NSLog(@"%@", object);
    }];
}

The error:

Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Cannot do a comparison query for type: __NSArrayI'

i think you should call a if statement in that code block because you has in NSError

 - (void)viewDidLoad

{
[super viewDidLoad];

// Do any additional setup after loading the view.

PFQuery *query = [PFQuery queryWithClassName:@"dog"];

[query getObjectInBackgroundWithId:self.objectId block:^(PFObject *object, NSError *error) {
if(!error)
 {
    // Do something with the returned PFObject in the gameScore variable.

    NSLog(@"%@", object);

     }
}];
 }
