Stuck on the second part of the For In Challenge

I am not sure how to get the For In loop printed values and append them to the array.

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

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

Hey:

This one is a simple, but sometimes hard to understand from the requirements. 

var results: [Int] = []

for multiplier in 1...10 {
var result = multiplier * 6 // Multiplying by 6

results.append(result) // Appending results to array

}

So we want to multiply the constant multiplier by 6 and add that result to a variable, and then appended to the array.

This is one way to do it. You can also do it this way.

var results: [Int] = []

for multiplier in 1...10 {
results.append(multiplier * 6) // Direct to the array.

Good luck
