iOS Objective-C Basics (Retired) Foundation Framework NSDictionary

NSDictionary *album = [[ NSDictionary alloc] initWithObjectsAndKeys:@ 2 "Abbey Road",@"title",@"The Beatles",@"artist",nil]; 3

4 NSMutableDictionary *albumMutable = [NSMutableDictionary dictionaryWithDictionary: album 5 ]; 6 [albumMutable setObject:@1957 forKey:@"year"]; 7

Hi Andre,

The problem you are having is due to the year you are passing to the setObject function. You've passed the year as a number literal (@number), when the problem asks for it as a string (@"number"). Additionally, the year they ask for in the prompt is 1969. Correcting these two errors should allow your code to validate.
