NSDictionary will not complete

I have the following piece of code.

-(NSDictionary *)getPlayers
{

    NSManagedObjectContext *context = self.genkDatabase.managedObjectContext;

    NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init];
    NSEntityDescription *entity = [NSEntityDescription entityForName:@"Team"
                                              inManagedObjectContext:context];
    fetchRequest.predicate = [NSPredicate predicateWithFormat:@"position ==[c] %@", @"Doelman"];
    [fetchRequest setEntity:entity];

    NSError *error;
    NSArray *fetchedObjects = [context executeFetchRequest:fetchRequest error:&error];
    if (fetchedObjects == nil) {
        // Handle the error.
    }else

        for (Team *info in fetchedObjects) {

            [_photos setObject:info.image  forKey:@"player_imgUrl"];
            [_photos setObject:info.name forKey:@"player_name"];

        }
    NSLog(@"%@",_photos);
    return _photos;

But for some reason or another my NSLog always gives (null) back. But when I do this

[_photos setObject:info.image  forKey:@"player_imgUrl"];
            [_photos setObject:info.name forKey:@"player_name"];

            NSLog(@"name: %@",info.name );
            NSLog(@"url: %@",info.image );

It gives the right data back.

Can somebody help?

Kind regards.

Make sure you have instantiated your _photos dictionary somewhere with the following line of code:

_photos = [[NSMutableDictionary alloc] init];

Just defining it as an instance variable or a property is not enough.
