How to convert Swift Bool? -> String?
let b1: Bool? = truelet b2: Bool? = falselet b3: Bool? = nilprint(b1?.description ?? "none") // "true"print(b2?.description ?? "none") // "false"print(b3?.description ?? "none") // "none"or you can define 'one liner' which works with both Bool and Bool? as a function
func BoolToString(b: Bool?)->String { return b?.description ?? "<None>"}
