Binary value of a Character in pure Swift -

i need convert character in binary string.

ex : c = 34 = "1000011"

my work in progress this. it's work "c" character :

import foundation  func chartobin(c:character) -> string {     let binaire = 34     return string(binaire, radix: 2) }  let c:character = "c" let b = chartobin(c) 

thank :

i solved problem code :

func stringtobinarystring (mystring:string) -> string {      // array of characters     let characterarray = [character](mystring.characters)      // array of asccii value     let asciiarray = characterarray.map({string($0).unicodescalars.first!.value})      // array of binary value     let binaryarray = asciiarray.map ({ string($0, radix: 2)})      // reduce in string     let r = binaryarray.reduce("",combine: {$0 + " " + $1})      return r }  // sample use : let r = stringtobinarystring("cc")
