Hi guys, I am having a hard time on this code challenge. Can someone post the code in the comments section? Thanks.
// Enter your code below
var results: [Int] = []
for multiplier in 1...10 {
print("\(multiplier) times 6 equals \(multiplier * 6)")
}

28,558 PointsThe problem with your code is that it's doing something different from what the task is actually asking, the task asks you to append the result of "multiplier * 6" to the results array within the loop. It does not ask you to print out any message or anything like that.
The easiest way of appending data to an array is to use the .append method which is found on arrays. Like this:
var example: [Int] = []
example.append(5) // You can type a pure value
// example now holds: [5]
example.append(10 * 2) // You can also type equations
// example now holds: [5, 20]
With the above knowledge in mind it should be relatively easy to solve this challenge, just change your print statement to one that appends "multiplier * 6" to the results array.
If you are still struggling with solving the challenge then I have posted the solution for you here, but it's always best to try to write the solution on your own first.
