Description

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

Does this issue reproduce with the latest release?

Yes

What operating system and processor architecture are you using (go env)?

What did you do?

I created a go package and used gomobile to bind it for iOS:

gomobile bind -v  -target=ios mypackage

And then referenced the framework in my iOS project

Then complied the iOS project

What did you expect to see?

The project should compile

What did you see instead?

error messge

ld: in /PATH_TO_THE_FRAMEWORK(go.o), building for iOS, but linking in object file (/PATH_TO_THE_FRAMEWORK(go.o)) built for , for architecture arm64 clang: error: linker command failed with exit code 1 (use -v to see invocation)

Contributor guide

Research direction
Analyze the linker error indicating an object file built for an unspecified architecture. Verify that gomobile bind targets the correct iOS architecture (arm64) and that the Xcode project settings match. Inspect the build flags used by gomobile and the framework's binary architecture with 'lipo info'.
