iOS Swift Functions and Optionals Parameters and Tuples Tuples

It's very confusing when the name of the function ("greeting") is the same as the name of a parameter/variable ("greetin

I find myself replacing the parameter/variable names with x, y, z to help me understand the concepts better.

Is this (i.e., functions and parameters/variables having identical names) something I need to get used to?

tuples.swift
func greeting(person: String) -> (greeting: String, language: String) {
    let language = "English"
    let greeting = "Hello \(person)"

    return greeting (greeting, language)
}

I'd actually start to make your own param/functions that names fit your own style of coding. When your projects begin to get bigger and bigger, the more clearly named options win. For your code I'd do something like:

func greeting(person: String) -> (myGreeting: String, language: String) {
    let language = "English"
    let myGreeting = "Hello \(person)"

    return greeting (myGreeting, language)
}

That way it's clearer to you, and also anyone else who is reading your code.
