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

Collections and control flow

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.

Hey guys, I'm kinda stuck here. Can someone help please.

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

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

Hi there! The good news is that you've got everything more or less set up correctly, but the print statement is not needed. Here's what it's looking for. Right now we have an empty array named results. What we want to do is build up that array by using the .append method inside our loop. The variable/constant multiplier will start at 1 and go to 10. Our ending array should look like this [6, 12, 18, 24, 30, 36, 42, 48, 54, 60].

I believe you can get it done with these hints, but let us know if more information is needed! Good luck! :sparkles:
