Brace yourself, because today we’re covering the first thing in Swift that many people have hard time understanding. Please keep in mind Flip Wilson's law: “you can't expect to hit the jackpot if you don't put a few nickels in the machine.”
Today you have only five one-minute videos to watch, just to make sure you have time to watch videos twice if you need to. Once you’ve completed each video you can read the optional extra section, and there’s a short test to help make sure you’ve understood what was taught.
Sometimes people ask me “why do you start some topics by saying they are hard – aren’t you just putting people off?”
Obviously my goal is not to put you off Swift. Instead, my hope is that when you struggle with something you don’t ever think to yourself “I’m not cut out for Swift.” If you find closures hard it’s not because you aren’t smart enough – they are hard, so it’s just a sign your brain is working properly.
Don’t despair. Sometimes fighting to learn something makes it stick in your head better – there is no learning without struggle!
