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

Need help with For / In Loops from the Swift 2.0 Collections and Control Flow Quiz

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.

var results: [Int] = []

for multiplier in 1...10 {

}

I am not sure what to do with this question. I have the For Loop setup but Im confused about how to solve this.

loops.swift 
var results: [Int] = []

for multiplier in 1...10 {

}

You're off to a good start. What they want you to do is to multiply the number you're on in the loop by 6, then append it to the array. You have to make sure that the number is an array before you append it. This is how I did it. 

var results: [Int] = []

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

I hope this helps.

Hi Tim,

The loop will go through the numbers between 1 and 10, and you need to append the result of mulitiplication of the multiplier*6 to the array. //// var results: [Int] = []

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