Swift conditionals challenge: compiles in Xcode not in browser

var results: [Int] = []

for n in 1...100 { // Enter your code below if (n % 3 == 0) && (n % 7 == 0) { results.append(n) } // End code }

print(results)

The printed result is: [21, 42, 63, 84]

What am I doing wrong?

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

for n in 1...100 {
    // Enter your code below
     if (n % 3 == 0) && (n % 7 == 0) {
         results.append(n)
     }
    // End code 
}

try this

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

Pardon me, my logic was wrong.

''' var results: [Int] = []

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

print(results)

''' ''' prints : "[7, 21, 35, 49, 63, 77, 91]\n" and passed.
