`DriveKitDelegate` is a protocol that can be passed as a parameter during the [DriveKit Core module initialization](https://docs.drivequant.com/get-started-drivekit/ios/..#drivekit-initialization). It gives useful events about the user lifecycle.

```swift
protocol DriveKitDelegate: AnyObject {
    func driveKitDidConnect(_ driveKit: DriveKit)
    func driveKitDidDisconnect(_ driveKit: DriveKit)
    func driveKit(_ driveKit: DriveKit, didReceiveAuthenticationError error: RequestError)
    func userIdUpdateStatusChanged(status: UpdateUserIdStatus, userId: String?)
    func driveKit(_ driveKit: DriveKit, accountDeletionCompleted status: DeleteAccountStatus)
}
```

}
```

| Value            | Description                                                                                |
