I cannot get past this question. My range is set to 1...10 which should be retrieving the first 10 multiples of 6.

What do i need to fix in my code to get to the next step? Help :)

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

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

Hey Bryce. Welcome to Treehouse.

For the first part of the challenge, you are only asked to create the for in loop. You added a print statement that was not asked for. Challenges are very strict. Often if you add more than what was asked, modify preloaded code, etc... you will get the "Bummer..."

So, all you need for Task 1 is

var results: [Int] = []

for multiplier in 1...10 {

}

Hey Jason,

Thank you for your response. I can get past task one but i cannot get past the second task. It keeps telling me that my range is off? Any ideas of how to pass this challenge? I've been stuck for quite some time lol.

Sincerely,

For the second task, you only need to add one line of code inside the for loop. The challenge wants you to append the value of 6 multiplied by each multiplier. With each iteration of the loop, the multiplier will be different and we want to add to the results array. This is done with .append()

var results: [Int] = []

for multiplier in 1...10 {
  results.append(multiplier * 6)
}

I would suggest, maybe, review the previous videos before moving on, because the loops get more complex and will move to switches and functions. Without a complete understanding of these past few videos, the next section will be very difficult. I often review and rewatch before moving on.
