Unity integration into Xcode ( Swift 4 )

Hi guys. I try to integrate a unity project ( using Unity 2018.2.4f1 - latest one at the moment ) into XCode ( version 9.4.1 - latest stable version at the moment ) and I encounter so so many errors in the last few days but I fixed all of them. Now I have this errors which I really don't know hot to fix them. I researched a lot and nobody have a right answer regarding this errors:

• "_OBJC_CLASS_$_ARWorldTrackingConfiguration", referenced from: objc-class-ref in ARSessionNative.o
• "_OBJC_CLASS_$_AROrientationTrackingConfiguration", referenced from: objc-class-ref in ARSessionNative.o
• "_OBJC_CLASS_$_ARAnchor", referenced from: referenced from: objc-class-ref in ARSessionNative.o
• "_OBJC_CLASS_$_ARPlaneAnchor", referenced from: objc-class-ref in ARSessionNative.o
• "_OBJC_CLASS_$_ARSession", referenced from: objc-class-ref in ARSessionNative.o

Is any chance that any of you to encounter this errors and to know a solution to fix them ?

My Library Search Path is set correctly if you are wondering about this: $(inherited) $(PROJECT_DIR)/NameOfMyProject/Unity/Libraries

Also I delete everything from Derived Data folder and I clean the project and rebuild so many times. I tried different versions of Unity to export the project and also I tried different versions of xCode to integrate the Unity project, none of them helped me.

Here is a screenshot with the errors:



Thank you guys !

 

Do you link against ARKit.framework in General -> Linked Frameworks and Libraries ?

 

Yes sir I did few days ago and that was the problem.
Now I have another error from UnityGraphicsMetal. When I launch the app is crashing and nobody know how can I fix this error.

Thank you if you are reading this !

 

Just a guess but did you enable Auto Graphics API in the iOS player settings? If not uncheck it and make sure both iOS and Metal API's are included.

The other thing I noticed is the HoloVideoObject...is that a plugin?
