1,736 PointsBummer about Bummer!
I'm writing the answer for this question: <pre> Let's assume we have a struct named Vehicle with a few stored properties as listed below. Let's create an initializer method and give the stored properties sensible initial values. We want to set the number of doors to 4, the number of wheels to 4 and the color to Blue. </pre>
I think I have the correct answer (tested in a Playground):
struct Vehicle {
var numberOfWheels: Int
var numberOfDoors: Int
var color: String
init(numberOfWheels: Int = 4, numberOfDoors: Int = 4, color: String = "Blue") {
self.numberOfWheels = numberOfWheels
self.numberOfDoors = numberOfDoors
self.color = color
}
}
When I submit this I keep getting:
<pre>
Bummer! You need to define a func
called init
inside of Vehicle
.

16,282 Pointsyou messed up the init method.
struct Vehicle {
var numberOfWheels: Int
var numberOfDoors: Int
var color: String
init() {
numberOfWheels = 4
numberOfDoors = 4
color = "Blue"
}
}

1,736 PointsWhy is it wrong if it successfully runs in XCode? I'm passing the expected values as defaults. If you still instantiate it with no args the object will be identical to the object created by your code.
let car = Vehicle()

16,282 PointsIt's not wrong it just doesn't work for this code challenge. They want you to practice what you learned not what you didn't learn.
