How should I fix my code?

I'm having issues with the code from this video, it's a warning that says: no visible @intrface for 'NSMutableDictionary' declares the selector 'alleys'. Heres the code.

for (NSString *string in [mutableBook allkeys])

if you need more code to figure this out I'll put it up. Thanks!

Try to write "allKeys" instead of "allkeys"
