What is wrong with the code? 

#import "Quote.h"

@implementation Quote

- (NSArray *) quotes {
  if (_quotes  == nil) {
    _quotes  = [NSArray arrayWithObjects:@"item1", @"item2", @"item3", nil];
  }
  return _quotes ;
}

- (NSString *) randomQuote {
    int random = arc4random_uniform(self.qoutes.count);
  return [self.quotes objectAtIndex:random];
}
@end

Keeps on asking me to use arc4random_uniform even though I am already using it.

You misspelled 'quotes'. The code should be

- (NSString *) randomQuote {
    int random = arc4random_uniform(self.quotes.count);
  return [self.quotes objectAtIndex:random];
}

or, in a more modern and compact fashion:

- (NSString *) randomQuote {
  return self.quotes [arc4random_uniform(self.quotes.count)];
}
