Why is this not correct in the challenge

The challenge specifies: if the number is both odd and a multiple of 7 add to the array var results: [Int] = []

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

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

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

It tells you to use the append method I think, not the compound operator.

var results: [Int] = []

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

While that is correct and works. I feel the request to append can work either way, and should not require the use of the append method. Thanks for the help.
