This is supposed to add values that are odd and divisible by 7 to an array(which it does in playground) how come this is not working in the challenge?
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 {
// Enter your code below
if n % 2 != 0 && n % 7 == 0 {
results += [n]
}
// End code
}

The result of those two actions are exactly the same, but the code is different. And the code checker is looking more at your code than your result for this challenge.
If you add to the array using the append
method like this:
var results: [Int] = []
for n in 1...100 {
// Enter your code below
if n % 2 != 0 && n % 7 == 0 {
results.append(n) // Add to the array using append rather than concatenation
}
// End code
}
Then your code will be accepted.

iOS Development Techdegree Student 1,136 PointsI just used the append method and it worked. Thank you for prompt response!
