Does not accept a valid answer. I tested this in my own Xcode compiler and it works fine, yet I get an error.

I've tested this in Xcode and it works fine (because it's valid math) yet it isn't accepted as the answer.

It's unclear what else you could possibly be looking for.

var results: [Int] = [] // print all numbers 1-100 that are both odd and multiples of 7. for n in 1...100 { if n % 2 != 0 && n % 7 == 0 { print(n) results.append(n) } }

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 
}

n % 2 !=0 // checks to see if the number is evenly divisible by 2 (i.e. "odd") n % 7 == 0 // checks to see if the number is a multiple of 7 (divisible by 7 w/no remainder)

Strange, all of the following worked when I tried it. Just make sure you have a space between != and 0.

var results: [Int] = []

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

var results: [Int] = []

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

var results: [Int] = []

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

Yep, I figured it out. Silly mistake - I was missing a space between the != and 0.
