What's the simplest way to convert from a single character String to an ASCII value in Swift?

Question

I just want to get the ASCII value of a single char string in Swift. This is how I\'m currently doing it:

var singleChar = \"a\"
println(singleChar.unicodeSc         


        

Answer 1

Swift 4.2

The easiest way to get ASCII values from a Swift string is below

let str = "Swift string"
for ascii in str.utf8 {
    print(ascii)

116
114
105
110
103

Swift 4+

Char to ASCII

let charVal = String(ch).unicodeScalars
var asciiVal = charVal[charVal.startIndex].value

ASCII to Char

let char = Character(UnicodeScalar(asciiVal)!)
