Describe the problem

MediaPipe and OpenCV together => 89 duplicate symbols

Complete Logs

I added opencv and mediapipe to my project with cocoapods. This is my Podfile.

platform :ios, '16.0'

target 'KYC' do
  # Comment the next line if you don't want to use dynamic frameworks
  use_frameworks!
	
  pod 'MediaPipeTasksVision', '0.10.5'
  pod 'OpenCV'
  # Pods for KYC

end

I need to use both libraries. Since MediaPipe does not explicitly include OpenCV as a dependency in its CocoaPods specification,
I need to add it separately to use OpenCV. In this case, I get an error of duplicate symbols. 
My question is How can I use these 2 libraries together with pod or otherwise? Can you help me please? 

When I build the project (any arm64 device), I get the following error.
Build setting left untouched, as set by "pod install" command.

hi @kuaashish, the build issues fixed as I can see. Now I can get a successful build. But I have a following issue.

this is the podfile that I use.

platform :ios, '16.0' target 'KYC' do use_frameworks! pod 'MediaPipeTasksVision', '0.10.10' pod 'OpenCV' end

When i try to import opencv in my .swift file it does not appear in import options. Any suggestions ?

@kers97 This is not related to the MediaPipeTasks vision framework.

But AFAIK, this should be because OpenCV is a C++ framework. It doesn't have Swift or Objective C interfaces. So you can't import it directly from Swift. You'll most probably have to create Objective C++ (.mm) classes that implement your OpenCV functionality, expose those classes using a bridging header to your Swift code and use them.

Thanks for your response I forgot that I have to put a bridging layer.
