Xcode 7.2/Unity Linker command error exit code 1

I’m trying to build a unity and then send it to my ipad .The build works fine but when xcode wants to send the app to my ipad I get this error :

"ld: '/Users/SygnusUser1/Documents/anomproject/Assets/U3DXT/Editor/lib/libU3DXTCoreExtras.a(UP_ALAssetRepresentation.o)' does not contain bitcode. You must rebuild it with bitcode enabled (Xcode setting ENABLE_BITCODE), obtain an updated library from the vendor, or disable bitcode for this target. for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)"

Im using xcode 7.2 and unity 5.3.3 . Any ideas on why this might be happening?

Check for Bitcode (yes Or No)
or again build from unity
