How to convert String to UnsafePointer and length

Question

When I using NSOutputStream\'s write method

func write(_ buffer: UnsafePointer, maxLength length: Int) -> Int
         


        

Answer 1

By far the easiest way (in Swift 5):

let s = "hello, world"
let pointer = UnsafePointer(Array(s.utf8CString))

Not sure how backwards compatible this is.
