Chris, you forgot one more way to deal with optionals, which stumbled upon while following along."Your a (you.somevalue ?? "Default value")" assuming that you is a class and somevalue is set to either a string or nil

Good explanation on what optionals are and how to unwrap them, although I'm still uncertain of what instances I would actually use them.

I think Swift is really stupid language. They are overcomplicating concepts just so that it differs from robust languages like C++/Java. In those languages you choose initialise or not a variable in a simple readable way. Swift is a overkill in my opinion. But the tutorials are amazing. Thanks bro 😀

Question, is the data in a class public/global and changeable from outside the class object? You were able to set post.title = yo from outside object without sending a message to the object's member function (in this case there was none), this seems very dangerous. Great video series, thanks for sharing and keep up the great work
