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 4.1

https://oleb.net/blog/2017/11/swift-4-strings/

let flags = "99_problems"
flags.unicodeScalars.map {
    "\(String($0.value, radix: 16, uppercase: true))"
}

Result:

["39", "39", "5F", "70", "72", "6F", "62", "6C", "65", "6D", "73"]
