Compiling failed with " Showing All Errors Only The i386 architecture is deprecated. You should update your ARCHS build setting to remove the i386 architecture. (in target 'clang_rt.builtins_i386_osx' from project 'CompilerRT')"

I met this error because I want to build swift project on my computer. After I cloned swift code to local, I executed ./utils/update-checkout --tag swift-6.0.3-RELEASE --clone. The folder looks like this.

Then I executed utils/build-script --release-debuginfo --debug-swift-stdlib --xcode --skip-ios --skip-watchos --skip-tvos --skip-early-swiftsyntax --skip-build-benchmarks --swift-darwin-supported-archs="$(uname -m)" at swift-project -> swift.

After that I got some projects at swift-project -> build -> Xcode-RelWithDebInfoAssert+stdlib-DebugAssert.

Next I clicked into llvm-macosx-arm64, then opened LLVM.xcodeproj to build.

Finally I got the error mentioned in the title.

How can I remove this i386 architecture? I don't know where to remove it.
