I define var Status in my struct & an Xcode error says I must add a semicolon before the (): var status: Status;()

It will not accept what the video lesson has:

struct Task {
    var description: String
    var status: Status()
       //no semicolon 
    init(description: String) {
        self.description = description
    }
}

but it will accept it if I add a semicolon after Status, like so:

struct Task {
    var description: String
   //semicolon added
    var status: Status;()

    init(description: String) {
        self.description = description
    }
}

Hi McKenna Rowe,

The code you have above shouldn't have worked at all as it contains a syntax error since you have a rouge set of parenthesis after your semi-colon, instead you would want something like the below.

enum Status {
    case Doing, Pending, Completing
}

struct Task {
    var description: String
    var status: Status

    init(description: String) {
        self.description = description
        self.status = .Pending
    }
}

Hope that helps.

If you just wanted to initialze your var status like in the video, juste change the colon ( : ) for for an equal ( = ). Lets say:

var variable = VarType()

A little remainder for this case: A colon is to define a type of a variable (or constant) and an equal sign is to assign a value to it.

Hope this helps.
