Treehouse Guest Teacherswift tuples?
I have no idea what it's asking me. I've been working on this for half an hour. Way too long for a question.
Challenge 1: Challenge task 1 of 3 Currently our greeting function only returns a single value. Modify it to return both the greeting and the language as a tuple. Make sure to name each item in the tuple: greeting and language. We will print them out in the next task.
Code they gave to edit:
func greeting(person: String) -> String {
let language = "English"
let greeting = "Hello \(person)"
return greeting
}
Answer:
func greeting(person: String) -> (greeting: String, language: String) {
let language = "English"
let greeting = "Hello \(person)"
return (greeting, language)
}
Challenge 2: Create a variable named result and assign it the tuple returned from function greeting. (Note: pass the string "Tom" to the greeting function.)
Answer is so far beyond me I really don't even know where to begin at this point. Nothing I've changed does anything except throw weird errors. Pretty please help :)

Just create a variable called result under the function and store the return value of the function in it, like this:
var result = greeting("Tom")

func greeting(person: String) -> (greeting: String, language: String) {
let language = "English"
let greeting = "Hello \(person)"
return (greeting, language)
}
var result = greeting("Tom")

Eric Wood
5,194 PointsIt wasn't working for me, either. Then I noticed a subtle difference. Greeting must be before language in the tuple and in the return in order for the test to work.
(greeting: String, language: String) <i>passes the test</i>
(language: String, greeting: String) <i>does not pass the test<i/>

This is what I have so far:
func greeting(person: String,) -> (greeting: String, language: String) {
var result = greeting("Tom")
let language = "English"
let greeting = "Hello \(person)"
return (greeting, language, result)
}
This is the error I get:
You need assign the return value of the 'greeting' function to 'result'.

Courses Plus Student 44,108 PointsAfter you pass task 1, you're not supposed to modify the function anymore. The rest of the code is written after the greeting function.
This is the solution for the first task:
func greeting(person: String) -> (greeting: String, language: String) {
let language = "English"
let greeting = "Hello \(person)"
return (greeting, language)
}
For the second task, just add this:
var result = greeting("Tom")
after the function.
You are calling the greeting function and passing the string literal "Tom" as a parameter. The function returns a tuple that you're storing in the result variable.

Treehouse Guest Teacherlol thanks Guess I am getting overcomplicated.
To be fair, they have us working from this as the original example, and they refactored it like 4 times (and it was refactored once more beyond this below code)
func searchNames (#name: String) -> (Bool,String) {
let names = ["George", "Mary", "Leonard", "Phil", "Fluffy", "Sparkles", "Hampton", "Joy"]
var found = (false, "\(name) is not a person in this group)")
for n in names {
if n == name {
found = (true, "\(name) is a person in this group")
}
}
return found
}
let (found,description) = searchNames(name: "Sparkles")
