# performRequests()

Starts the specified authorization flows during controller initialization.

```
func performRequests()
```

## Discussion

When authorization succeeds, the system relays that information to the controller’s [`delegate`](/documentation/AuthenticationServices/ASAuthorizationController/delegate) by calling the [`authorizationController(controller:didCompleteWithAuthorization:)`](/documentation/AuthenticationServices/ASAuthorizationControllerDelegate/authorizationController(controller:didCompleteWithAuthorization:)) method with an authorization instance. If authorization fails, the system calls the [`authorizationController(controller:didCompleteWithError:)`](/documentation/AuthenticationServices/ASAuthorizationControllerDelegate/authorizationController(controller:didCompleteWithError:)) method instead.

Some authorization flows require a presentation context to ask the user for information or consent. Adopt the `ASAuthorizationControllerPresenting` protocol in one of your app’s classes, and set an instance of that class as the authorization controller’s `presentationController`.
