Did try:
let s = "a 🚲 bicycle"
let endGray = "c"
if let rangeOfB = s.rangeOfString(endGray )
{
let length = distance(s.startIndex, rangeOfB.startIndex)
println( "\(endGray) at composed character index index \(length)")
// 6
}
let ns = s as NSString
let range = ns.rangeOfString(endGray)
let nsLength = range.location
println( "\(endGray) at NSString index \(nsLength)") // 7
Using "length" with addAttribute:value:range would NOT be quite correct, would
it?
Seems like "nsLength" is more appropriate.
Kind regards,
Gerriet.
