I'm trying to implement Spring iOS Animation Library, but quite a few errors were generated. Code in question:

let startIndex = hex.endIndex.advancedBy(1)

Additional Code:

if hex.hasPrefix("#") {
        let startIndex = hex.endIndex.advancedBy(1)
        _   = hex.substring(from: startIndex)
    }

  • Did you try `.advanced(by: 1)` – dan Sep 09 '16 at 19:41

    Why are you trying to advance past the `endIndex`? In any case, the full error message tells you the solution – "*'advancedBy' is unavailable: To advance an index by n steps call 'index(_:offsetBy:)' on the CharacterView instance that produced the index.*" – Hamish Sep 09 '16 at 19:46

    Thanks folks, the link by Leo helped me out. – Royalty Club Sep 09 '16 at 19:51
  • Assuming you're trying to remove the `#` from the string – you could also do `String(hex.characters.dropFirst())` – Hamish Sep 09 '16 at 19:58
