I have tried to replace a specific char in a string. I want to replace the the seconde o for an e. I have tried to use:

  var s   = "bolo"
  var charIndex = advance(1, 1)
  s.replaceRange(Range(start: charIndex, end: charIndex), with: "e")
  println(s)

You can use too the function stringByReplacingOccurrencesOfString, in the following way:

var s = "bolooooooo"
s.stringByReplacingOccurrencesOfString("o", withString: "e", options: NSStringCompareOptions.LiteralSearch, range: Range<String.Index>(start: advance(s.startIndex, 2), end: s.endIndex))

The output is :

boleeeeeee

You just need to specify the string startIndex (s.startIndex) when using advance as follow:

var s = "bolo"
let charIndex = advance(s.startIndex, 3)
s.replaceRange(charIndex...charIndex, with: "e")
println(s)  // "bole"
