@phantumcode I hope you are doing well. I am writing to inform you about this issue. When I am on a call with someone, this issue arises. I hope this will help to rectify the problem. Thanks

It seems like something in your call back is not running on the main thread

14 Runner  0x9dc8 FaceLiveDetectionController.callback(_:) + 45 (FaceLiveDetectionController.swift:45)

Can you share your code snippets and validate everything is correctly configured in your controller?

@harsh62 Thanks for writing back to me. Here is the code snippet. Please check it. I just wanted to inform you that we have created a Flutter app and then integrated this library natively. Thanks for your help; it is much appreciated.

Your onCompletion if handling UI should run on the main thread.

onCompletion: { result in
                    switch result {
                    case .success:
                        self.callback("success")
                    case .failure(let error):
                        self.callback(error.message)
                    }
                }

It should look something like this.

DispatchQueue.main.async {
                    switch result {
                    case .success:
                        self.callback("success")
                    case .failure(let error):
                        self.callback(error.message)
                    }
}
