invalid value? what is going on here...

ok, my code challenge says this: Let's add the year of the album to the 'albumMutable' variable. Where the key is a NSString 'year' and the value is also a NSString '1969'. I did that, but it says: Bummer! The year set is not the correct value. here is my code…

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

What you have there, @1969, actually produces an NSNumber. To produce an NSString, you need to quote the actual string just like what you did with @"year"

That means that there is an error in the video because I ran into the same problem because it was not quoted in the video at the Mutable part
