Is it possible to generate .xcframework file with gomobile?

I built the .framework file with gomobile with the following command:

gomobile bind -target ios -o ../frameworks/MyFramework.framework

After that I tried to build .xcframework file with this command

xcodebuild -create-xcframework -framework "MyFramework.framework"
-output "MyFramework.xcframework"

But it shows error:

error: binaries with multiple platforms are not supported
'/Users/nicco/myFramework/MyFramework.framework/MyFramework'

So looks like the problem is in gomobile framework generation process.

So I see 2 solutions:

  1. To generate .xcframework file with gomobile.
  2. Change the .framework build process for being able to convert .framework generated file to .xcframework

How to do it?

Thanks for taking the time to open this issue. Unlike many projects, the Go project does not use GitHub Issues for general discussion or asking questions. GitHub Issues are used for tracking bugs and proposals only.

Check https://github.com/golang/go/wiki/Questions for some other venues, more suited for asking questions.

Hi @valself this could help to generate and xcframework

you need to generate a framework for each architecture

mkdir arm64
gomobile bind -ldflags="-w -s" -target=ios/arm64 -o ./arm64/Openpgp.framework github.com/jerson/openpgp-mobile/openpgp

mkdir amd64
gomobile bind -ldflags="-w -s" -target=ios/amd64 -o ./amd64/Openpgp.framework github.com/jerson/openpgp-mobile/openpgp

and then just merge with xcode command

xcodebuild -create-xcframework \
	-framework ./arm64/Openpgp.framework \
	-framework ./amd64/Openpgp.framework \
	-output Openpgp.xcframework

and thats all, hope this help
