What version of Go are you using (go version)?

$ go version
go version go1.14.1 darwin/amd64

$ sw_vers
ProductName:	Mac OS X
ProductVersion:	10.15.5
BuildVersion:	19F101

What did you do?

clangwrap.sh

#!/bin/sh
# This uses the latest available iOS SDK, which is recommended.
# To select a specific SDK, run 'xcodebuild -showsdks'
# to see the available SDKs and replace iphoneos with one of them.
SDK_PATH=`xcrun --sdk $SDK --show-sdk-path`
# cmd/cgo doesn't support llvm-gcc-4.2, so we have to use clang.
CLANG=`xcrun --sdk $SDK --find clang`
exec $CLANG -arch $CLANGARCH -isysroot $SDK_PATH "$@"

go build -buildmode=c-archive -o libtest_amd64.a main.go

I believe you need -tags=ios to build for iOS:

$ go build -buildmode=c-archive -tags=ios -o libtest_amd64.a main.go

See also #38485.

@eliasnaur good, It works fine. I want to know where I can find supported tags.

I don't know where supported tags are listed, sorry. Please ask your question on the golang-nuts list. FWIW, the ios tag is probably being replaced with GOOS=ios when #38485 is resolved.
