Structs Part 2

Initializers

Initializers are special methods that provide different ways to create your struct. All structs come with one by default, called their memberwise initializer

struct User {
    var username: String
}

var user = User(username: "Saurabh")

print(user.username) //Saurabh

We can provide our own initializer to replace the default one. For example, we might want to create all new users as “Anonymous” and print a message, like this:

struct User {
    var username: String

    init() {
        username = "Anonymous"
        print("Creating a new user!")
    }
}

our initializer accepts no parameters, we need to create the struct like this:

var user = User()
user.username = "Saurabh"

print(user.username)
//Saurabh
