Is the following a valid definition of the init method?

Hello everyone,

I'm going through the struct videos and at the end I have this quiz. One of the questions I don't know why the provided code isn't valid.

struct Task { var description: String var completed: Bool

init() {
  self.completed = false
}

}

Can anyone tell me the valid way to initiate a struct?

Your init method is totally fine. Except your initializer should initialize all the stored properties. 

struct Task { 
   var description: String 
   var completed: Bool

   init() {
      self.completed = false
      self.description = "a description"
   }
}

if you want the user of this struct to specify the values, don't add an init method. A struct by default gives you an initializer.

let task = Task(description: "a description", completed: true)

The initialization of a struct is similar to the initialization of a class

let task = Task()
