Am I missing something here?

Obviously yes, you are. The line:

@interface ToDoItem : NSObject <NSCoding>

declares the interface for the ToDoItem class, which inherits from NSObject and implements to the NSCoding protocol. NSObject still doesn't implement to the NSCoding protocol, it's your class that does.
