Swift 4.1.

func isValidPhone(phone: String) -> Bool {

      let phoneRegex = "^[0-9]{6,14}$";
      let valid = NSPredicate(format: "SELF MATCHES %@", phoneRegex).evaluate(with: phone)
      return valid
   }

func isValidEmail(candidate: String) -> Bool {

       let emailRegex = "[A-Z0-9a-z._%+-]+@[A-Za-z0-9.-]+\\.[A-Za-z]{2,}"
       var valid = NSPredicate(format: "SELF MATCHES %@", emailRegex).evaluate(with: candidate)
        if valid {
            valid = !candidate.contains("..")
        }
        return valid
  }
