Challenge Task 2 of 2
Inside the body of the loop, we're going to use the multiplier to get the multiple of 6. For example, if the multiplier is 1, then the multiple is 1 times 6, which is equal to 6.
Once you have a value, append it to the results array. This way once the for loop has iterated over the entire range, the array will contain the first 10 multiples of 6.
I'm struggling to grasp how this is supposed to come together. I've re-watched the videos leading up to this 3 times now and I guess it's just not making sense. This is the closest I think I've gotten with it. TIA for the advice!
// Enter your code below
var results: [Int] = []
for multiplier in 1...10 {
var results = "\(multiplier * 6)"
}

First your creating a string 10 times over, but your doing nothing with it. That variable you created within the brackets of the loop, "results", is limited in scope, it disappears after the loop has run. You need to append what work is done within the brackets, each time the loop is run to the array variable named "results".
Second, you are creating a string and assigning it to a variable named results, you really want to create an Int here and append it to your results array. Notice the name I choose for the product of multiplier * 6.
var results: [Int] = []
for multiplier in 1...10 {
var result = multiplier * 6
results.append
}

results.append(multiplier * 6)
}
This also works.

1,081 PointsAhhh this is very enlightening. I had suspected that making a string literal was going to be incorrect due to it not an Int. I had not considered using the append method within the loop but now that I'm looking at it, that makes perfect sense. Many thanks, Chris!
