Init argument naming conventions

InitArgsConvention.playground.swift

// Which convention for init args do you prefer?

// Naming the arguments the same as the fields requires explicitly naming self
class MyFirstClass {
    var i: Int
    var s: String

    init(i: Int, s: String) {
        self.i = i
        self.s = s
    }
}

// Using different local names allows you to avoid explicitly naming self, but requires cluttering your init signature
class MySecondClass {
    var i: Int
    var s: String

    init(i _i: Int, s _s: String) {
        i = _i
        s = _s
    }
}

MyFirstClass(i: 1, s: "hello")
MySecondClass(i: 1, s: "hello")
