I don't know what it fails

I think it's good but it says it's bad. I don't know why.

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

for n in 1...100 {
    if n % 2 != 0 && n % 7 == 0 {
        results += [n]
    }
}

Hi there,

Your answer compiles correctly in XCode, but for this specific instance, they're asking you to use the append method, so try this instead of the results += n:

results.append(n)
