IOS not support bitcode

I see the bitcode checkbox in IOS platform configuration,
but if I check to use bitcode, it will build fail, the error message:

‘/Users/Shared/Epic Games/UE_4.16/Engine/Binaries/IOS/UE4-Launch-IOS-Shipping.a(Module.Launch.cpp.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
