2,146 PointsEnum Challenge Task
I'm kinda confused why it's saying it was expecting to be type Int but it wasn't. Am I missing something here?
enum Speed: Int {
case Slow = 10
case Medium = 50
case Fast = 100
}
var turtleSpeed = Speed(rawValue: 10)

This challenge has caught a few users off guard because of the last example used in the previous video, what the task is actually asking for is the rawValue
of Speed.Slow
which we can get by simply using the below code.
var turtleSpeed = Speed.Slow.rawValue
Why didn't your code work?
When using the rawValue
initializer we're simply creating a new instance of the enum
for that given value, in this case you've specified you want the enum for the rawValue
of 10 which is Speed.Slow
, if the rawValue
couldn't be found a nil
value is returned instead.
Hope that helps.

4,867 PointsThis is, how it should look like:
enum Speed: Int {
case Slow = 10
case Medium = 50
case Fast = 100
}
var turtleSpeed = Speed.Slow.rawValue
Have a look on how you should call a enum member or itΒ΄s raw value ;-)
I hope this helped

So instead of
var turtleSpeed = Speed(rawValue: 10)
use this
var turtleSpeed = Speed.Slow.rawValue
That should work!!
Good luck bro keep it going!!
