3,941 PointsDictionary Challenge Roadblock - mutableDictionary
I'm trying to add the key of NSString 'year' to my NSDictionary and make its value a string '1969'. I copied the instructors code and adapted it directly for this challenge, although I think that the challenge is asking me to make the value a string whereas the instructor's video may not have required the value type to be a string. What should I be doing differently?
NSDictionary *album = @{@"title": @"Abbey Road", @"artist": @"The Beatles"}; NSMutableDictionary *albumMutable = [NSMutableDictionary dictionaryWithDictionary: album]; [albumMutable setObject:@1969 forkey:@"year"];

There's a great video on the right "Tips for asking questions" that might help you with posting your code in the forum.
The solution for Challenge task 3 of 3 "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'." is
NSDictionary *album = @{@"title":@"Abbey Road", @"artist":@"The Beatles"};
NSMutableDictionary *albumMutable = [NSMutableDictionary dictionaryWithDictionary: album];
[albumMutable setObject:@"1969" forKey:@"year"];
and the literal @1969 for a NSNumber normally would be ok but you might want to have a look here
