Collections and control flow, the last code challenge isn't passing

So in xcode I have confirmed that these are all added to the array. 7 numbers are added. I'm not sure why it is failing.

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

for n in 1...100 {
    // Enter your code below
    if n % 2 != 0 && n % 7 ==0 {
      results += [n]
      }
    // End code 
}

Sorry code is actually:

var results: [Int] = []

for n in 1...100 { // Enter your code below if (n % 2 != 0) && (n % 7 == 0) { results += [n] } // End code }

added numbers are [7, 21, 35, 49, 63, 77, 91], this means I have all the odd multiples of 7

You need to append the results

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

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

    results.append(n)

    }

    // End code 
}

Hi Izaac!

So, I copied your code and I change "results += [n]" for "results.append(n)" and it worked
