# SACrashDetectionManager

Provides registration and management of Crash Detection events.

```
class SACrashDetectionManager
```

## Overview

Use this class to determine Crash Detection availabilty on iPhone, detect authorization status, and register for Crash Detection events. Not all iPhones support Crash Detection, so verify that [`isAvailable`](/documentation/SafetyKit/SACrashDetectionManager/isAvailable) returns <doc://com.apple.documentation/documentation/Swift/true>.

Check the value of [`authorizationStatus`](/documentation/SafetyKit/SACrashDetectionManager/authorizationStatus) to determine if the person designates this app on their iPhone to receive Crash Detection events. If the value is not [`SAAuthorizationStatus.authorized`](/documentation/SafetyKit/SAAuthorizationStatus/authorized), set [`delegate`](/documentation/SafetyKit/SACrashDetectionManager/delegate) and call [`requestAuthorization(completionHandler:)`](/documentation/SafetyKit/SACrashDetectionManager/requestAuthorization(completionHandler:)) to request authorization.

After your app has authorization to receive Crash Detection events, adopt [`SACrashDetectionDelegate`](/documentation/SafetyKit/SACrashDetectionDelegate) and implement [`crashDetectionManager(_:didDetect:)`](/documentation/SafetyKit/SACrashDetectionDelegate/crashDetectionManager(_:didDetect:)). If a vehicular crash occurs, the system calls the method with the Crash Detection event.

## Topics

### Determining availability

[`available`](/documentation/SafetyKit/SACrashDetectionManager/isAvailable)

A Boolean value that indicates if Crash Detection is available.

[`authorizationStatus`](/documentation/SafetyKit/SACrashDetectionManager/authorizationStatus)

A value that indicates if the person authorized the app to receive Crash Detection events.

### Requesting authorization

[`delegate`](/documentation/SafetyKit/SACrashDetectionManager/delegate)

The object that receives Crash Detection events.

[`-  requestAuthorizationWithCompletionHandler:`](/documentation/SafetyKit/SACrashDetectionManager/requestAuthorization(completionHandler:))

Requests permission to access Crash Detection information.
