I am new to Swift, and I need help with my code!

Can you help me complete this task, I need to check is the number n is even and if it is divisible by seven, and if so add to the array results.

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

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

Hi, you need to use the % modulo operator which checks if the remainder of n divided by 2 or 7 is equal to zero.

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

Thank you Lee, your awnser is correct apart from the n % 7 != 0, it is correct like this: n % 7 == 0
