How do I append values in the for in loop to results array?

This is what I have so far and it's working fine in palyground:

var results: [Int] = [] for multiplier in 1...10 { print("(multiplier) times 6 equal to (multiplier * 6)") }

loops.swift 
// Enter your code below
var results: [Int] = []
for multiplier in 1...10 {
print("\(multiplier) times 6 equal to \(multiplier * 6)")
}

You've nearly got it! This challenge doesn't ask you to print anything, so you can get rid of the print statement.

To append values to the results array, all you have to do is use the append function on results in the for loop:

results.append(/* INSERT VALUE HERE */)

I hope this helps!
