Code works in Xcode, but gives me an error in browser/tutorial..

It looks like the tutorial is having trouble with 'n', but other than that I have no clue where to start.

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

for n in 1...100 {
    // Enter your code below

    if (n % 2 == 1) && (n % 7 == 0) {
      results += [n]
    }
    // End code 
}

The issue is that the code checker for this task is quite picky. It expects you to use the append method to add numbers to the array rather than using concatenation like you are doing.

The resulting array will be the same either way, but unless the code checker sees the append method being used it won't pass the code.

Here is your solution modified so it will pass the challenge:

var results: [Int] = []

for n in 1...100 {
    // Enter your code below

    if (n % 2 == 1) && (n % 7 == 0) {
      results.append(n)
    }
    // End code 
}
