How to make an empty object in swift - swift

Question

How do I initialize an empty object in swift? This is what I have but it wants the parameters too
var userInfo:User = User()
init(email: String, isVerified: String, profileImageURL: String, reputation: String, twitterHandle: String, userName: String) {
self._email = email
self._isVerified = isVerified
self._profileImageURL = profileImageURL
self._reputation = reputation
self._twitterHandle = twitterHandle
self._userName = userName
}

Answer 1

Create the class/struct with optional properties like this
struct Employee {//struct or class
var name: String?
var number: String?
var position: String?
}
Then you can create an object without any value, with some value
let emp = Employee()
let emp = Employee(name: nil, number: nil, position: nil)
let emp = Employee(name: "abc", number: nil, position: "xyz")
By creating a init method with default values parameter can be ignored while creating an object
struct Employee {
var name: String?
var number: String?
var position: String?
init(name: String? = nil, number: String? = nil, position: String? = nil) {
self.name = name
self.number = number
self.position = position
}
}
let emp = Employee()
let emp = Employee(name: "abc", number: "124", position: "xyz")
let emp = Employee(name: "abc", position: "xyz")
let emp = Employee(number: "124")
let emp = Employee(name: "abc", number: "124")

Answer 2

I assume you are creating empty User objects so that the information can be filled in later on. There are two problems I can see with this: one, object properties will all have to be variables and second, it's easy to make mistakes and pass the wrong information since the object does not always correspond to a real entity.
A better approach would be to define a set of parameters that are mandatory for a User object to be defined, and let every other parameters either be optional parameters, or give them default values. For example, if we choose username and email to be mandatory, and let profile image be optional, and isVerified to have a default value of false:
class User {
var userName: String
var email: String
var isVerified: Bool
var profileImageURL: String?
init(userName: String, email: String, isVerified: Bool = false) {
self.userName = userName
self.email = email
self.isVerified = isVerified
}
}
