Parser crash

[matthart-com]

Instantiating defaultParser on real device crashes. The fix I did is the following, plus instantiating via setDefaultParser(with: Configuration)

private static var _defaultParser: Parser?
    public static var defaultParser: Parser {
      get {
        if _defaultParser == nil {
          _defaultParser = Parser(with: Configuration.configuration(fromJSONResource: ConfigurationType.v3)!)
        }
        return _defaultParser!
      }
      set {
        _defaultParser = newValue
      }
    }
