hope this fix your issue I can't remember the name of them but you've mixed up your %@, %ld thingies.
Your NSLog uses %@ and works.

I hope this helps . I'm not sure what you're trying to do but: it's certain that the poor array object has no idea what and how your own custom class does, its best possibility to print an instance of your class is to call its description method, which you see, and which is not really helpful. You maybe want to do two things:
I. If you only want to print your objects like this, override the description method of your class and use some format string (given that you haven't written a single line of code I have to fall back to guess):
code :
- (NSString *)description
{
    return [NSString stringWithFormat:@"Name: %@, address: %@", self.name, self.address];
}
for (QuestionData *d in surveyQuestions)
{
    NSLog(@"%@", d.name);
    // etc.
}

like below fixes the issue App crashes when trying to update an UILabel with a NSString. Showing the same NSString on console works. , title is not NSString, it is NSArray
so
code :
-(void)connectionDidFinishLoading:(NSURLConnection *)connection
{
    if (self.connectionData)
    {
        NSError *error;
        self.dict = [NSJSONSerialization JSONObjectWithData:self.connectionData options:kNilOptions error:&error];
        self.matchesArray = self.dict[@"matches"];

        NSArray *title = [self.matchesArray valueForKey:@"title"];
        NSLog(@"NSString TITLE contains: %@", title);
        self.titleLabel.text = [title lastObject];
    }
}

I hope this helps . Eventually, I found the answer myself here: https://community.oracle.com/thread/4069783
The problem didn't have anything to do with the PL/SQL Function. Prior to version 5.1.3 of ORACLE APEX any Chart requires the same number of data points to exist in each series. So, you need to add data densification in your query yourself. I agree with the following quote of an ORACLE developer that this wasn't optimal...

To fix the issue you can do As i see you are trying to center the label on the screen, you may try to add this to your code, on gameover func:
1.Try change the position to this
code :
gameOverLabel.position = CGPoint(x: (self.scene!.frame.width / 2) - (self.scene!.frame.width * self.scene!.anchorPoint.x) / 2, y:(self.scene!.frame.height / 2) - (self.scene!.frame.height * self.scene!.anchorPoint.y))
gameOverLabel.zPosition = 10 //A number higher than any other zPosition 
gameOverLabel.fontSize = 30 //Adjust it to what you want
var gameOverLabel: SKLabelNode! 
let meteor = SKSpriteNode(imageNamed: "meteor") 
gameOverLabel.removeFromParent()

wish help you to fix your issue Why are you trying to use NSLog for this? That's for showing messages in the log.
You want NSString stringWithFormat:.
