Swift Closures Explained - The ONLY video you'll ever need!
You may have heard "Closures are functions!", but what does that mean EXACTLY? In this video I break it down by starting from basics, and building up to what makes a closure... a closure.
They can be super confusing for beginners. Following code paths and logic is tricky, but I am here to explain it all to you.
We'll start from basic concepts like variables to computed variables, to functions, to closures. I think linking them all together and slowly adding more complexity to the explanation will help you to fully understand how they work.
Let me know if you also want me to do one for Value vs Reference types. I know that's been done a bunch too, but I think I have a super simple and intuitive way of explaining them for newcomers.
