iOS Enumerations and Optionals in Swift Objects and Optionals Enums with Raw Values

Posted by Raghav Sharma

Why is the code not correct? Am I missing something?

Please have look at my code. The question does not seem clear. I am not able to go ahead as the code seems to incorrect.

This is the question: "Let's get in some practice creating enums with raw values. Declare an enum named Compass with a raw value of type Int.

Give the enum 4 members: north, south, east and west and assign them default raw values.

Assign the enum value Compass.south to a constant named direction, by using a raw value with Compass' initializer method."

My Code: enum Compass: Int{ case north = 1 case south case east case west } let direction = Compass.south

enums.swift 
enum Compass: Int{
    case north = 1
    case south = 2
    case east = 3
    case west = 4
}


let direction = Compass.south.rawValue

This is what the code challenge is wanting:

let direction = Compass(rawValue: 2)

I think this code challenge is too confusing since the video tells us to do it the way you have above. Here's a link to apple's Enum page. You can search for raw values and there is a section all about it. The section you are looking for is called, Initializing from a Raw Value.
