How do I append the result to the array?

whats wrong here

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

for n in 1...100 {
    // Enter your code below
    if (n % 3 == 0 ) && ( n % 7 == 0 ) {
    print ( "Number is odd and even")
    } else {
    print (" not true")

    results.append(n)
}

You are missing a closing brace, so your code won't be compiled.

var results: [Int] = []

for n in 1...100 {
    // Enter your code below
    if (n % 3 == 0 ) && ( n % 7 == 0 ) {
        print ( "Number is odd and even")
    } else {
        print (" not true")
        results.append(n)
    } // <--- This brace was missing
}

However, this is not the final solution, I am just pointing out the compilation error, they way you append elements to an array works :) Please find below the solution that worked for me:

var results: [Int] = []

for n in 1...100 {
    if n % 2 != 0  &&  n % 7 == 0  {
        results.append(n)
        // results += [n]  <-- This would also append n to the array
    }
}
