Loop Challenge Fails Appending to array

Loop challenge fails with the message "Make sure the results array contains the first 10 multiples of 6" Not sure where I went wrong

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

That should work. I guess it's this line that won't compile with code check:

("\(multiplier) \(multiplier * 6)")`

It's not a print statement and will only work in playgrounds.

// Enter your code below
var results: [Int] = []
for multiplier in 1...10 {
    results.append(multiplier)
}

Hope that helps :)
