Hi,

I've followed this link:

I followed the tutorial up to trying to build the project it self but it here shows these error:
Undefined symbols for architecture arm64: "_OBJC_CLASS_$_PHImageManager", referenced from: objc-class-ref in NativeGallery.o "_OBJC_CLASS_$_PHImageRequestOptions", referenced from: objc-class-ref in NativeGallery.o "_OBJC_CLASS_$_PHAssetCollection", referenced from: objc-class-ref in NativeGallery.o "_OBJC_CLASS_$_PHFetchOptions", referenced from: objc-class-ref in NativeGallery.o "_OBJC_CLASS_$_PHAssetCollectionChangeRequest", referenced from: objc-class-ref in NativeGallery.o "_kUTTypeMovie", referenced from: +[UNativeGallery pickMedia:savePath:] in NativeGallery.o "_OBJC_CLASS_$_PHAssetChangeRequest", referenced from: objc-class-ref in NativeGallery.o "_OBJC_CLASS_$_PHPhotoLibrary", referenced from: objc-class-ref in NativeGallery.o "_OBJC_CLASS_$_PHAsset", referenced from: objc-class-ref in NativeGallery.o "_kUTTypeImage", referenced from: +[UNativeGallery pickMedia:savePath:] in NativeGallery.o +[UNativeGallery imagePickerController:didFinishPickingMediaWithInfo:] in NativeGallery.o "_kUTTypeVideo", referenced from: +[UNativeGallery pickMedia:savePath:] in NativeGallery.o ld: symbol(s) not found for architecture arm64 clang: error: linker command failed with exit code 1 (use -v to see invocation)

I've tried to find these error in the issues but so far no luck and adding
-DNET_4_0 to OTHER_CFLAGS doesn't seems to help either. (rather i already have added it from following the article), was there anything i'm missing.
I'm using Xcode 11.3(11C29) "latest i believe", and my unity version is 2018.4.12f1.

P.S: In the XcodePostScript i added absolute path because i'm not sure how am i going to put relative path from the folder i'm building, but after building, a little console shows up and ask me to choose for the filepath and build the script, i did that but end up needing to remove many unity-exported files reference from my native-swift project's build phases "compile-sources". Should i try to redo the tutorial from the begining again?

P.S.S: Why is there no support/documentation on native-iOS for vuforia sdk. The official site gives outdated sources and when i submit a forum question ticket, nobody replies me. :(
