initializers

Heres the question "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."

This is what i put, 

struct Vehicle {

  var numberOfWheels: Int
  var numberOfDoors: Int
  var color: String

init()

numberOfWheels [4]
numberOfDoors [4]
color [Blue]

}

your syntax is not correct. you need opening and closing brackets after init() and your code needs to go between them, and you need to assign the values using propertyName = value syntax. you only use brackets when working with arrrays and dictionaries. 

struct Vehicle {

  var numberOfWheels: Int
  var numberOfDoors: Int
  var color: String

init() {

numberOfWheels = 4
numberOfDoors = 4 
color = "Blue"

}

}
