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

I don't know what I have to do in the second task

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.```loops.swift

// Enter your code below var results: [Int] = [] for multiplier in 1...10 { print("(multiplier) times 6 is (multiplier * 6)")}

It is asking for you to add the answers of 6 times 1, 6 times 2... up to 6 times 10 to the results array. So to add the answers to the results array to have to call the variable name dot append method ( add parameters ) like below. Hope this helps and makes sense.

var results: [Int] = []

for multiplier in 1...10 {

// Append(add) first 10 multiples of 6 to results array

results.append(multiplier * 6)
}
