I have the following ClassRoom Struct
struct ClassRoom: Codable {
let name: String
let classId: String
let date: String
}
While I am forming a ClassRoom object, I do not need date object.
// do not need date object here!,
let classRoom = ClassRoom(name: "Math", classId: "12343")
Missing argument for parameter 'date' in call
But I need date object when I decode the ClassRoom.
You need to make your date be optional.
Two approaches:
You can keep using the compiler synthesized memberwise initializer. For it to use nil as a default value, you need to make the date variable mutable:
struct ClassRoom: Codable {
let name: String
let classId: String
var date: String? = nil
}
If you want to keep it mutable, you'll have to add your own initializer, with a defaulted parameter, like so:
struct ClassRoom: Codable {
let name: String
let classId: String
let date: String?
init(name: String, classId: String, date: String? = nil) {
self.name = name
self.classId = classId
self.date = date
}
}
nil, and made mutable:var date: String? = nil.
