i looked over the video several times, but his example wasn't like this one. this one is easier i'm sure, what am i over thinking?. please help

enum.swift 
enum Speed: Int {
    case Slow = 10
    case Medium = 50
    case Fast = 100
}
let turtleSpeed = Speed(rawValue: 10)

You're not completely off, no - the rawValue access is a little strange. I wouldn't worry too much about it.

As always, remember to have a look through the documentation. That really can help you and you do get used to it over time.

I just Googled Swift Enum Rawvalue and got this link which does help your question if you scroll around a bit.

Don't get me wrong, by all means ask in here, but the documentation is also a great help!

The challenge was to get the raw value from Slow, not to pass it "10", as in the above where you have: Speed(rawValue: 10). Their example with Coins was in the format: Coin.Penny.rawValue
