I am mis-understanding the question during code challenge?

I am really not understanding the second half of this question....

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

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

This question (which, if I remember correctly, is the second question of this type, the first being the multiple of 5 one) wants you to append the result from the loop into an array as opposed to printing it out.

  1. The challenge is not asking you to print anything; therefore, there is no need for the print statement. It is asking you to append the value to the results array
var results: [Int] = []

for multiplier in 1...10 {

results.append(multiplier * 6)

}

Thanks! I misunderstood the question and was trapped in the mindset. The comments here helped.

Thanks for posting the question Dipesh, it threw me off but now that I look at Jeff's answer its makes sense. You really have to go back and forth between task 1 and 2 to get what the instructor is asking you to do.
