Besides for the purpose of this video example of Optionals does func sendNoticeto have to be an Int?

Just wondering why it couldn't have been a string so you don't need to use an optional?

Exactly, optionals can be of any type. Amit could have easily not used an Int and used a String instead, but I feel he also wanted to introduce the toInt() function as well.

Thank you, I wanted to make sure I wasn't missing anything and I am glad I am actually starting to get it.
