On the last challenge, i put 1969 but it tells me that the year is wrong. Is this a bug or have I done something wrong?

Is this a bug? Thank you for your help.

NSDictionary *album = @{ @"title":@"Abbey Road", @"artist":@"The Beatles"};
NSMutableDictionary*albumMutable = [NSMutableDictionary dictionaryWithDictionary:album];
[albumMutable setObject:@1969 forKey:@"year"];

Where the key is a NSString 'year' and the value is also a NSString '1969'.

According to the challenge description, '1969' has to be a NSString as well.

[albumMutable setObject:@"1969" forKey:@"year"];

Thank You! I was stuck on that for ages. I didn't realise the speech marks signified an NSString.
