Bummer!The year set is not the correct value

NSDictionary *album=@{@"title":@"Abbey Road",@"artist":@"The Beatles"}; NSMutableDictionary *albumMutable=[NSMutableDictionary dictionaryWithDictionary:album]; [albumMutable setObject:@1969 forKey:@"year"]; don't know what's wrong in the code

year probably needs to be a string, not an NSNumber:

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

below is your full code with the year changed to a string:

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