var results: [Int] = []
for n in 1...100 { if (n % 2 === 0) && (n % 7 === 0) { results += n } }
var results: [Int] = []
for n in 1...100 {
if (n % 2 === 0) && (n % 7 === 0) {
results += n
}
}

Courses Plus Student 15,510 PointsA couple of small errors.
You are checking if the number (n) is even (if n%2 == 0) when you should be checking if odd (if n%2 != 0)
Also, should be appending to the array ... Something like:
if (n%7 == 0 && n%2 != 0) { // not equals 0 rather than equals 0
results.append(n) // appending, as per challenge requirement
}
FYI: If you want to use the += notation outside of the challenge environment you'd need to add an array to the existing array, something like:
results += [n]
That won't pass the challenge, but works outside of the challenge environment. I'd suggest sticking with 'best practice' and using the inbuilt swift methods -> array.append(value)
Really good effort though Keep practicing, and happy coding.
