Actually the assembly file compiled with "-fembed-bitcode" flag in the static lib. In Apple developer forums, it was mentioned that, Including assembly files with "-fembed-bitcode" should just work fine. If I use a direct assembly file into Xcode App, then its working fine.
I did a bit research with the linker tool (ld) and I could see that, it was searching for .o file for assembly code externally which is not correct because it is an archive lib.
