Error IOS build arm64

Hi there,
I’ve stumbled upon this error while packaging but cannot find my error.

UATHelper: Packaging (iOS): ld: symbol(s) not found for architecture arm64
UATHelper: Packaging (iOS):
UATHelper: Packaging (iOS): clang: error: linker command failed with exit code 1 (use -v to see invocation)

I am sure that in the config .ini file arm64 support is TRUE (both development and shipping). Besides that armv7 is NOT supported(set false). I’ve purpousely set minimum os to IOS 11 (only 64 bit devices).

I’m remote Building because I have c++ and some objective c Code
My Linker Flags are: $(inherited) -ObjC

What do I Need to do? Please help I’m finished and this annoying issue keeps me from realeasing !
