What did you do?

Use gomoblie to build 2 framework with different lib for iOS
lib1.xcframework
lib2.xcframework

add to target in xcode and when build get 31 duplicate symbols for architecture arm64 gomobile error!

there is any way to create framework with random symbols or something to prevent this error?
Xcode log:

31 duplicate symbols for architecture arm64

Linker command failed with exit code 1 (use -v to see invocation)

also i read this but no answer #37241

What did you expect to see?

What did you see instead?

I believe you need to build all of the Go libraries as a single framework. (You can use a Go package with import _ "example.com/foo" statements to combine them into one target for go build.)

@bcmills I tried it but there is a problem.
so I want to implement two different versions of the same library. when I Built the xcframework, I got conflicts in module versions, functions, and protobuf conflicts.
I think the only way is that I should build them separately
