Question: If I have 

```
protocol AppearingTextContainer {
  func clipBounds() -> ()
}
extension AppearingTextContainer where Self: UIView {
  func clipBounds() { self.clipsToBounds = true }
}

```

then a class that adopts my protocol CustomView: AppearingTextContainer is not forced by the compiler to implement clipBounds. If I remove the extension it won't compile. Is there any way to enforce CustomView to call clipBounds without having to delete the default clipBounds implementation?

Thanks

Answer: 
As *freakish* already pointed out, `sendStatus` sets and sends the status.

This means that if you want to both set a status and send a body you have to use `status`. For example, you want to set an error status, and send a body with a JSON that explains why the error occured, you first have to set the status (using `status`), and then send the JSON (using `send`). If you had already set the status with `sendStatus`, it is no longer possible to send the JSON, because you already used a form of sent.
no it's not for special routers like delete
The diffrence is `res.status()` only sets header and when you send response (`res.send()`) it will send to user
but `res.sendStatus()` sends the response at the moment without response body
