I do not understand how to "append the value to the results array" for the following line of code. If anyone could help

do not understand how to "append the value to the results array" for the following line of code. If anyone could help I would greatly appreciate it. I tried doing the results.count but that only tells me how many numbers are odd and divisible by 7, also it does not append it to the results array.

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

for n in 1...100 {
    // Enter your code below

    if n % 2 != 0 && n % 7 == 0 {

   }

    }

    // End code

Check out the documentation on how to add a value to an array, https://developer.apple.com/library/ios/documentation/Swift/Conceptual/Swift_Programming_Language/CollectionTypes.html#//apple_ref/doc/uid/TP40014097-CH8-ID105

Hi David,

Maybe try:

var results: [Int] = []

for n in 1...100 {
    // Enter your code below

    if n % 2 != 0 && n % 7 == 0 {
      results.append(n) // You might also be able to use += or .extend()
   }

    }

    // End code
