Today we’re going to get into the real detail of Swift: operators and conditions. This can sometimes trip folks up when they are learning, because as Joseph Campbell once said, “computers are like Old Testament gods: lots of rules and no mercy.”
Don’t worry, though. Sure, if you get a condition wrong then your code might not work at first, but it costs nothing other than a little head scratching to fix it up and try again.
In fact, a common mistake folks make while learning is they have a fear of running their code. Trust me on this: while you’re following all the code here, none of the code you write can somehow break your computer. So, make a change and run it. Make another change and run that. Just try changing your values until you feel comfortable with what’s happening – it all helps.
Today you have ten one-minute videos to watch, and you’ll meet things like operator overloading, switch statements, and more. Once you’ve watched each video there’s a short test to help make sure you’ve understood what was taught.
