Can´t solve this one

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'.

you need to use the setObject forKey method on your mutable dictionary. you can add a key and an object like so:

[myMutableDictionary setObject:@"some string" forKey:@"keyName"];

the task tells you that the key needs to be @"year" and the value/object needs to be @"1969"
