在gomobile连接上运行示例测试时出错

Question

I'm trying to run a Gomobile test on the terminal here is my code I have done like instruction from https://www.sitepoint.com/ios-and-android-programming-with-go/

1. go get golang.org/x/mobile/cmd/gomobile
2. gomobile init
3. gomobile build -target=ios golang.org/x/mobile/example/basic

Which gives me the error:

gomobile: go build -tags ios -ldflags=-w -o=/var/folders/4q/2vddqkyd3rv4tvzfbnsssbkm0000gn/T/gomobile-work-977299939/amd64 golang.org/x/mobile/example/basic failed: exit status 2 # golang.org/x/mobile/example/basic /Users/ibct/.gvm/gos/go1.9.6/pkg/tool/darwin_amd64/link: running /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang failed: exit status 1
