2 months ago @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?

2 months ago @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.

import Foundation
import SwiftUI
import UIKit
import FaceLiveness
class FaceLiveDetectionController: UIViewController {
var sessionId: String?
var flutterResult: FlutterResult!
var hostingController: UIHostingController<FaceLivenessDetectorView>?
override func viewDidLoad() {
super.viewDidLoad();
configureFaceDetection()
}
private func configureFaceDetection() {
if let sessionID = self.sessionId {
let faceView = FaceLivenessDetectorView(
sessionID: sessionID,
region: "ap-south-1",
disableStartView: true,
isPresented: .constant(true),
onCompletion: { result in
switch result {
case .success:
self.callback("success")
case .failure(let error):
self.callback(error.message)
}
}
)
hostingController = createHostingController(with: faceView)
addHostingControllerAsChild(hostingController!)
configureConstraints(for: hostingController!.view)
}
}
private func callback(_ res: String) {
hostingController?.dismiss(animated: true, completion: nil)
if (res == "success") {
flutterResult("success")
} else {
flutterResult(FlutterError(code: "error", message: res,details: nil))
}
}
private func createHostingController(with rootView: FaceLivenessDetectorView) -> UIHostingController<FaceLivenessDetectorView> {
return UIHostingController(rootView: rootView)
}
private func addHostingControllerAsChild(_ hostingController: UIHostingController<FaceLivenessDetectorView>) {
addChild(hostingController)
view.addSubview(hostingController.view)
}
private func configureConstraints(for view: UIView) {
view.translatesAutoresizingMaskIntoConstraints = false
NSLayoutConstraint.activate([
view.topAnchor.constraint(equalTo: self.view.topAnchor, constant: 10),
view.bottomAnchor.constraint(equalTo: self.view.bottomAnchor),
view.leadingAnchor.constraint(equalTo: self.view.leadingAnchor),
view.trailingAnchor.constraint(equalTo: self.view.trailingAnchor)
])
}
}
Main Delegate file
import UIKit
import Flutter
import Amplify
import AWSCognitoAuthPlugin
@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
override func application(
_ application: UIApplication,
didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
) -> Bool {
do {
try Amplify.add(plugin: AWSCognitoAuthPlugin())
try Amplify.configure()
print("Amplify configured with auth plugin")
} catch {
print("Failed to initialize Amplify with \(error)")
}
let controller: FlutterViewController = window?.rootViewController as! FlutterViewController
let methodChannel = FlutterMethodChannel(name: "LIVE_VERIFICATION_CHANNEL", binaryMessenger: controller.binaryMessenger)
methodChannel.setMethodCallHandler { [weak self] (call, result) in
if call.method == "startLiveVerification" {
guard let args = call.arguments as? [String: Any],
let sessionId = args["sessionId"] as? String else {
result(FlutterError(code: "INVALID_ARGUMENT", message: "Invalid session Id",details: nil))
return
}
print("session id is \(sessionId)")
let faceLivenessController = FaceLiveDetectionController()
faceLivenessController.sessionId = sessionId
faceLivenessController.flutterResult = result
faceLivenessController.modalPresentationStyle = .fullScreen
controller.present(faceLivenessController,
animated: true,
completion: nil)
} else {
result(FlutterMethodNotImplemented)
}
}
if #available(iOS 10.0, *) {
UNUserNotificationCenter.current().delegate = self as UNUserNotificationCenterDelegate
}
GeneratedPluginRegistrant.register(with: self)
return super.application(application, didFinishLaunchingWithOptions: launchOptions)
}
}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)
}
}@harsh62 will check. Thanks
