Assigning a fixed value to a variable in a struct-CodePudding

I have a struct that is used when parsing JSON data. I want one of the fields, name, to be a fixed name, see below...

struct QuestionConfiguration: Codable, DisplayOrderable {
    var name: String? = "QuestionConfiguration"
    
    var isRequired: Bool
    var displayOrder: Int
    var title: String = ""
    var questions: [Question]
}

Each time, when I then try and access a QuestionConfiguration object, name is nil.

I have tried using an init(), with parameters and without. I have tried String? and String.

Does anyone know how I can achieve this so that name is the same for each object, without having to pass it to the object?

CodePudding user response：

Simply by changing this line - var name: String? = "QuestionConfiguration" to this - let name = "QuestionConfiguration"

Full code -

struct QuestionConfiguration: Codable, DisplayOrderable {
        let name = "QuestionConfiguration"
        
        var isRequired: Bool
        var displayOrder: Int
        var title: String = ""
        var questions: [Question]
    }

Note - If property is fixed then you should not call it as variable b'coz variable means it may change
