Undefined Symbols on iOS build using ARFoundation

[fourthedesign]

Describe the bug
I have a project in Unity that uses Arfoundation and Airar. I successfully built for android, but when transferring to XCode and building for a device I received the following errors:
Undefined symbol: MetToUIImage(cv::Matconst&)
Undefined symbol: UIImageToMat(UIImageconst& cv::Mat& bool)
Undefined symbol: cv::warpPerspective(..)
Undefined symbol: cv::gtePerspectiveTransform(...)
Undefined symbol: cv::Mat::deallocate()
Undefined symbol: cv::fastFree(void*)
Which seems to be Linker connected error

To Reproduce
Steps to reproduce the behavior:

1. Copied libAirarColorMap.a and opencv2.framework (v3.4.11 as suggested) to Plugins/iOS in Unity
2. Set the appropriate settings in Player Settings as suggested in Readme
3. target iOs Version 11+
4. Built for iOS and opened in XCode
5. Built for iOS device
6. Build failed with the above errors.

Desktop (please complete the following information):

• Unity 2022.3.6
• ArFoundation 5.0.7
• ARKit 5.0.7
• XCode 14.3

Additional context
What we tried:

1. setting opencv2.framework to "Embed&Sign" in Xcode Frameworks and Libraries
2. Setting Library Search Paths and Header Search Paths to opencv2.framework
3. Clean build folder in XCode
