iOS Swift 2.0 Collections and Control Flow Control Flow With Loops For In Loops

Not quite sure how to append for in loop To Array.

I just learned how to do for in loops in Swift 2.0 and although it makes sense to me, the code challenge is asking me to get a certain value from my loop and then express that in the earlier provided array, a process I'm having trouble with.

Specifically, the question is

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.

Any advice? Thank you!

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

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



}

Your previous code was closer to the correction solution!

Take a look through the Array documentation here, and look for append() function:

Collection in Swift

edit: a bit more...

If I wanted to append the number 101 to my results [Int] array, I would say:

results.append(101)

And, if I need to multiple 101 by 6 and append, I could do:

results.append(101 * 6)

And, if I was required to append 1 through 10 to my array, I could do something like this:

for num in 1...10 {
  results.append(num)
}

Now, put all of these together. :)

Wow this was much simpler than I thought! Thank you for spelling it out like that, very useful! Fixed it up by adding results.append(multiplier * 6). Thanks again!
