Issue with implementation in iOS

SDK

Hi, i am trying to integrate DeepAR in a flutter with https://pub.dev/packages/deepar_flutter. But i am facing some issues with the implementation, as i am not able to build the app itself. I am getting Undefined symbol Error.

Launching lib/main_development.dart on iPhone 13 Pro Max in debug mode...
main_development.dart:1
Xcode build done.                                           48.1s

Could not build the application for the simulator.

I have updated my findings in the github issue. It builds in physical device, but just keeps showing loading, that is the ar controller is stuck initializing. its not even building for Simulator.
I am using

  • Xcode Version 14.2 (14C18)
  • Flutter 3.7.4
  • deepar_flutter: ^0.0.5
