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

You can use NSString's characterAtIndex to accomplish this...

var singleCharString = "a" as NSString
var singleCharValue = singleCharString.characterAtIndex(0)
println("The value of \(singleCharString) is \(singleCharValue)")  // The value of a is 97
