I don't get how i'm supposed to use the results array

I've tried a number of different ways to solve this task but I didn't come across how to solve it.

loops.swift
// Enter your code below
var results: [Int] = []

for multiplier in 1...10 {
    print("\(multiplier) times 6 is equal to \(multiplier * 6)")
}

You're printing out the results which isn't what they want. They want the results array to contain the results So the first time through the loop it should append 6 to the array. Then 12... all the way up to 60. Take a look at my solution:

// Enter your code below
var results: [Int] = []

for multiplier in 1...10 {
    results.append(multiplier * 6);
}

At the end the results array should look like this [6, 12, 18, 24, 30, 36, 42, 48, 54, 60]. Hope that clarifies things!

Okay, thank you that was exactly what I needed. It did work out well and I passed the challenge. But sometimes it can be hard to understand. You see english is my second language and i'm only 14.

You're doing great! And your English is excellent (as far as I can see). As a note: I'm in the reverse position. English is my first language and Swedish is my second :)
