Initialization of Swift class

init.swift

import Foundation

class Foo: CustomStringConvertible {

    static func calculatedValue(for thing: String) -> String {
        return thing.uppercased()
    }

    func calculatedValue(for thing: String) -> String {
        return thing.uppercased()
    }

    private let thing1: String
    private let thing2: String

    init(thing: String) {
        thing1 = thing

        // 'self' used in method call 'calculatedValue' before all stored properties are initialized
//        thing2 = calculatedValue(for: self.thing1)

        // Works, even though `self` is referenced with parameter `self.thing1`
        thing2 = Self.calculatedValue(for: self.thing1)
    }



    var description: String {
        return "\(thing1) \(thing2)"
    }
}

let f = Foo(thing: "hello")
print(f)
