ReplayKit Won't Record Twice in One Session

Question

I am using ReplayKit in an app to record the visible screen with some text and a video playing. The issue I am facing is that ReplayKit is working just fine for the first screen recording, but if I am to record again in the same session (ie without closing the app) it runs into this error:

MyViewController[423:39346] viewServiceDidTerminateWithError:: Error Domain=_UIViewServiceInterfaceErrorDomain Code=3 "(null)" UserInfo={Message=Service Connection Interrupted}

In this scenario, I am actually trying to screen record on the same ViewController (only with a different video being played and some text content altered). Below is my recording code:

@objc func startRecording() {
        let recorder = RPScreenRecorder.shared()

        recorder.startRecording{ [unowned self] (error) in
            if let unwrappedError = error {
                print(unwrappedError.localizedDescription)
                print("NOT Recording")
            } else {
                self.video.play()
                print("Recording")
                self.isRecording = true
            }
        }

        recordIcon.isHidden = true
        ring.isHidden = true
    }

    @objc func stopRecording() {
        let recorder = RPScreenRecorder.shared()

        recorder.stopRecording( handler: { previewViewController, error in
            if let error = error {
                print("\(error.localizedDescription)")
            }

            // Handling iPads
            if UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiom.pad {
                previewViewController?.modalPresentationStyle = UIModalPresentationStyle.popover
                previewViewController?.popoverPresentationController?.sourceRect = CGRect.zero
                previewViewController?.popoverPresentationController?.sourceView = self.view
            }
            if previewViewController != nil {
                self.previewViewController = previewViewController
                previewViewController?.previewControllerDelegate = self
            }
            self.present(previewViewController!, animated: true, completion: nil)
        })
        isRecording = false
        recordIcon.isHidden = false
        ring.isHidden = false
        return
    }

    func previewControllerDidFinish(_ previewController: RPPreviewViewController) {
        dismiss(animated: true)
    }

Any help on this is greatly appreciated. I'd hate to force users to have to reopen the app before recording again.

It might be that your app keeps the screen recording longer than it should. If this is the case, try implementing the discardRecording(handler: @escaping () -> Void) function. Here are more details on the discardRecording.

Thank you for the comment. I attempted your solution but encountered the same error. Looks like I may just have to ask the users to reopen the app for every new recording – Coding Hobbies Jul 10 '19 at 14:33
No problem! One last thing you can try is removing/comment out the `self.video.play()` function in your `startRecording()` method. I haven't seen that in tutorials or the apple docs so it might be this. Here is another thread with the same error code but different problem. [link](https://stackoverflow.com/questions/40131751/error-while-running-custom-keyboard-running-on-simulator-swift) Besides that, I hope you figure it out! – James Castrejon Jul 10 '19 at 17:19
looks like I had no luck, but will write here if I find a fix. fyi the self.video.play() is my own code that plays the AVPlayer so not relevant to this issue. Thank you – Coding Hobbies Jul 15 '19 at 15:44
