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

Stuck on first part of Challenge. How do I add the for loop into the var results array?

How do I add the for loop into the var results array?

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

The aim is a 6 times table in the array.

Something like this should work: var results: [Int] = []

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

So for the multiplier, it first stores 1, multiplies this by 6, appends the result (6) to the results array, and after that it moves onto the next number which is 2 and does the same process again.

Let me know if this helps! :) If not, I can try explaining it better.

Hi Matt, to add each result to the array, use:

results.append(multiplier * 6)

Also, you won't need let multiplier = or the square brackets that surrounds the loop. The constant itself is declared in:

for multiplier in 1...10

How do I do this using a for loop like the ask requests?
