[compiler-rt][libfuzzer][iossim] How to build libfuzzer libraries for iossim?

[Picasso-r]

I built an iOS app demo on my Mac using Xcode and now I want to fuzz it with LibFuzzer. After reading the LibFuzzer documentation, I found that it has a feature to use LibFuzzer as a library. However, when I modified my code and tried to link libclang_rt.fuzzer_no_main_osx.a, I encountered an error:

In /usr/local/Cellar/llvm/16.0.6/lib/clang/16/lib/darwin/libclang_rt.fuzzer_no_main_osx.a(FuzzerCrossOver.cpp.o), 
building for iOS Simulator, but linking in object file built for macOS,
file '/usr/local/Cellar/llvm/16.0.6/lib/clang/16/lib/darwin/libclang_rt.fuzzer_no_main_osx.a' for architecture x86_64

From my understanding, I need to specify the target architecture as iossim when compiling compiler-rt to obtain the corresponding library: libclang_rt.fuzzer_no_main_iossim.a.
I'm not sure about the specific terminal command for this( New to this area. T^T). I'm hoping to get some help here.
