I'm working with a model -

struct Planet : Codable {
    var name : String
    var distance : Int
    var isSelected : Bool?
}

The data is being fetched from the server and only name and distance are provided by the server. I have added isSelected to keep track of the item being selected.

I'm using JSDecoder class to parse this data.

I tried using var isSelected : Bool ?? false but it gives compiler error.

Since the isSelected value is not provided by server, is there any way I can set the default value false to this?

`var isSelected: Bool? = false` – Tamás Sengel Jul 15 '18 at 07:20
My suspicion is that adding an `isSelected` property is a bad approach anyway. Remember that structs are copy on write. You may be better off with some other data structure to track selection; a `Set` for example – Paulw11 Jul 15 '18 at 07:35
@the4kman when decoding, the value will be overwritten with `nil`. – Papershine Jul 15 '18 at 07:42
