Xcode build arm64 failed

Hi.
I don’t understand, since today my xcode build failed because of an undefined symbols for architecture arm64, wich i don’t know what it is.

"
Undefined symbols for architecture arm64:
OBJC_CLASS$_InfobipMediaView”, referenced from:
objc-class-ref in IBMediaView.o
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
"

I google this kind of problem and i’m supposed to change something in the build Settings → Architecture. But it looks alright.

And i show you the error message after building:

I can build for armv7 armv7s only but i need arm64 to put it on appstore.

Thanks for helping.

UP please.
I’m still stuck on the same problem since a week.

I take it you never got a reply here? I’m in the same boat.

Unity 5.1.1f1. Build Player Settings:
Scripting Backend - IL2CPP
Architecture - Universal

Xcode 6.4. Build Settings:
Architecures - Standard architectures (armv7, arm64)

Has anyone else

Same exact issue ^^^
