x/mobile: Duplicate symbol '_OBJC_CLASS_$_Universeerror'

[KiranKumar6236]

Environment

Xcode - 12.4
Language - Objective-C Project
Project Type - React Native

Issue

Converted a couple of go projects/libraries to iOS frameworks (.xc).
Trying to use those 2 in one iOS project but facing compiler issue like "Duplicate symbol 'OBJC_CLASS" which are related to objects of autogenerated files like Universe.objc.h.

Approach tried: 1

Did prefix binding of the go files
gomobile bind -target ios -prefix My

Result: Failed - Binder didn't bind the objects under Universe.objc.h. so the issue of duplicate symbols persists

Approach tried: 2

Update the linker flag config in Xcode
-objc

Result: Failed- The issue of duplicate symbols persists

What version of Go and gomobile do you use? Thanks.

@cherrymui @changkun I've tried with Go 1.16 and 1.17 (1.18+ for some reason does not work, but that's a separate issue), followed the same logic as @KiranKumar6236 but didn't work. I think the best approach would be to be able to prefix those "base" classes (Universeerror) and other methods. Could you advise on the best way to achieve that?
