what would employee look like if we used a guard instead of a if let?

guard let hourlyEmployee = employee as? HourlyEmployee else {
return // or something else
}
hourlyEmployee.payWages(for: 10.0)
But guard-let may not work as nice as if-let in his example, because if the guard-let fails, no other code after the guard-let will execute, whereas in his example, he had more to do with the other employee type even if the first condition failed.
