Code Challenge for Swift: if statements & logic operators

its supposed to check if n is odd and if n is a multiple of 7. I am pretty sure about the first check but the second is saying I can't an immutable value even though its var.

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

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

You wanted to use the == (comparison operator) in second condition of your if statement but wrote a single "=".

var results: [Int] = []

for n in 1...100 
{
  if (n % 2 != 0) && (n % 7 == 0) //Fix this line here so that you have the right comparison operator
  {
    results.append(n)
  }
}
