Congrats for the hands-on approach. The examples really turn POP easier and funnier to understand!

I watched WWDC 2015 talk on Protocol Oriented Programming last week and was looking for a tutorial that converted an OOP approach to POP - this is the best resource I've found on it. Awesome video, thank you!

Taking a OOP design and converting it to POP is a great idea. Clarifies the differences very well. I’m with the guy below asking for a silent keyboard though 😊

it's a good tutorial video for showing POP from OOP. expecting more from you brother.

For a simple situation like in the video, you could simplify your code further by replacing redundant protocols with an Enum. Here's an example:
enum RacerType {
    case gasoline(_ fuelTankSize: Int, _ fuelConsumption: Int)
    case electric(_ battery: Int, _ electricityConsumption: Int)
    case bike(_ canEnterSmallVillage: Bool)
}
protocol Racer {
    ...
    var type: RacerType { get } }

Following that, your Vehicle struct has a simpler definition: struct Vehicle: Racer, LandVehicle. Instances are then even easier to create, like so:
let honda: Vehicle = .init(name: "Honda", type: .gasoline(50, 6), numberOfWheels: 4)
let tesla: Vehicle = .init(name: "Tesla Model S", type: .electric(100, 20), numberOfWheels: 4)
let bike: Vehicle = .init(name: "Bike", type: .bike(true), numberOfWheels: 2)

Instead of extending Racer protocol individually, I extended it once and used a switch statement to get RacerType's case-specific results. I achieved a 0.99-to-1 functionality as in the video.

POP, TDD? - Let me explain to you with one simple example.
Smash the like button if you find it helpful, and YES! QUIETER KEYBOARD THIS TIME :)

Hey nice video would you be able to do a video showing us how you code on the HHKB as a programmer? Ie - how you navigate the lack of arrows, selecting text, copy/paste, etc?

Good job, learned a lot. Keep up please

I would have given you 1000 likes if I could!

wowww <3. Is it necessary to override info in all classes? I mean we can override info just in one extension. No?

great content! just use a silent keyboard next time please =)
