'NSUInteger conversion loses integer' warning message in XCode

http://stackoverflow.com/questions/19372312/objective-c-implicit-conversion-loses-integer-precision-nsuinteger

I'm not sure how to remove this warning message. I found numerous questions on stackoverflow relating to the same warning message, however still really stuck here, any tips?

It's a warning attached to the predictionArray

- (IBAction)buttonPressed:(UIButton *)sender {

    //NSString *myString = @"It is decidely so";
    //self.predictionLabel.text = @"Definately yes";
    NSUInteger index = arc4random_uniform(predictionArray.count);

    self.predictionLabel.text = [predictionArray objectAtIndex:index];
}

Basically you need to convert the count. If you want an explanation then please see the link Leon posted above.

NSUInteger random = arc4random_uniform((uint32_t) self.predictions.count);
