Obtaining-characters-from-a-String-in-SWIFT.mkd

Previous Swift 2.0, the option .character for String's type, was obtained using advance and startIndex (pretty much a pain in the butt, so make it an extension and you could have the characters :P )

var kString = "My string"
var countString = count(kString)

for i in 0...countString - 1 {
  let index = advance(kString.startIndex, i)
  print("INSIDE FOR \(kString[index])")
  self.labelAmount.text?.append(kString[index])
  
}
