Why is my answer not correct?

This code works perfect in the playground, but the system does not accept it.

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

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

    if ((n % 2) == 0) && ((n % 7) == 0) {

        results.append(n)
    }

    // End code 
}

What you did is incorrect because it asked you to check for odd values not even values. n % 2 == 0 checks for all even values. The challenge wants n % 2 != 0 which would be the odd values.

var results: [Int] = []

for n in 1...100 {
  if (n % 7 == 0) && (n % 2 != 0) {
    results.append(n)
  }
}
