OIC.
Your solution doesn’t work in Swift 3, because the String.init (_:) method has
been renamed to String.init (describing:), and actually produces a textual

let str = "hi".nulTerminatedUTF8
let padded = str.withUnsafeBufferPointer() {
return String(format:

I don’t understand this. Is %9d a typo for %9s? Or are we now talking about
numbers instead of strings? I don’t get
