Fail To Build with Unity SDK

Hey guys,
i am the developer of a app for a large Arena based Show, and after integrating this SDK with our product, when trying to build for IOS we get this error.

Undefined symbols for architecture arm64:
“_png_init_filter_functions_neon”, referenced from:
_png_read_filter_row in libaffdex-native.a(pngrutil.o)
OBJC_CLASS$_ALAssetsLibrary”, referenced from:
objc-class-ref in libaffdex-native.a(cap_ios_video_camera.o)
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

iv tried some google searches and some trawling through these forums but havent found a viable solution so far.
please note we use Unity.
this is a very urgent issue and a big thanks in advance to those who can give us a hand.

See the info here: Build error with OpenCV's libpng when using Affdex for Unity with another third-party video-streaming library in Swift

Hey Andy,
i saw that Post earlier but none of the fixes seemed to work.

Any other ideas?

if it helps i use Vuforia as well.

Hi, that other link captures our best current advice. If we discover any other tips or tricks, we’ll pass them along.

So found the SDK that was clashing with this one.
i was using firebase.
so iv cut firebase now and it all seems to work!
