fixed

Good kata, but there is a problem with Swift unit tests and example

func swap(_ s: String, n: Int) -> String { // _ is missed before n

XCTAssertEqual(swap("the quick broWn fox leapt over the fence", 9),
"The QUicK BrowN foX LeaPT ovER thE FenCE")

Nice Kata, Thanks!

Really nice kata, but there is a problem with Swift. Some of tests fails till change return type from String to String?

Poor description and tests. Absolutely terrible

Thanks man

I see the description, but I suggested making the result of function more logical than now.

Not a suggestion. The description says: "If L or M are empty return string is "". Anyway too late to change.

I have just one question to this kata.

Why I should return empty string if total amount is zero?

I recon this result is better than empty string.

e.g. - "(A : 0) - (B : 0) - (C : 0) - (D : 0)"
