iOS Objective-C Basics (Retired) Foundation Framework NSDictionary

What's wrong with my code? D:

Here's the challenge task: "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'."

Here's my code:

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

The challenge error is: "Bummer! The year set is not the correct value."

I'm not sure what I've done wrong. I went ahead and copied and pasted my code into Xcode and iterated over the dictionary with an NSLog and the value and key of "year = 1969" is logged to the console.

Hi Jacob,

Looks like you're simply missing the double quotes from @1969, instead it should be @"1969".

Ah, I see! I didn't read the instructions carefully enough. I see now that they did actually ask for 1969 to be a NSString object. Thank you!
