- [Bear] Do you want a black belt in Swift? Well, higher-order functions are your kung fu and I am your sensei. We're going to look at what makes Swift unique and powerful. Higher-order functions, gone are the dark days of Objective-C. If you've been confused by map, filter, CompactMap, and reduce, whoa, that's a tricky one there, right? No more. We'll chop the boards and bricks and become the ninjas of Swift. We'll see closures in a new light and pass them around like old library books.
I'm Bear Cahill, Head Binary Sequencer at Brainwash Inc. And I can't wait to give you your black belt in higher-order functions.
