Day 9: Using 'self' or "Referring to the current instance"

Forums > 100 Days of SwiftUI

Hello. I went through this section of Day 9, and I understand what is required from the syntax, but I don't get the purpose of why you would ever do it.

Using the code sample below (from Paul's Review of the same section), the new constant "Conference" is alraedy providing the parameters for the "name" and "location" variables. Then why is this init method even necessary?

Is it just that this example is overly simplified? Because there's no explanation of why you would ever use this.

Thanks!

struct Conference {
    var name: String
    var location: String
    init(name: String, location: String) {
        self.name = name
        self.location = location
    }
}
let wwdc = Conference(name: "WWDC", location: "San Jose")
