[Samuel Michael]

Anyone have any experience adding Multiplatform framework to a iOS workspace which uses Carthage for managing frameworks?

[Samuel Michael]

It seems like pack for Xcode is not working because of the way the frameworks get added via Carthage, I am trying the CocoaPods plugin to circumvent this just checking if anyone had some tips

[spierce7]

I have done this successfully with carthage

[spierce7]

Carthage allows a pre-compiled framework

[Samuel Michael]

Awesome, how do I add pre-compiled framework to Carthage?

[Samuel Michael]

is it in the CartFile or somewhere else I’m a little out of my element

[spierce7]

the documentation is inconsistent on it

[spierce7]

so it took a lot of trial and error

[Samuel Michael]

😞

[spierce7]

so you want to compile a fat framework

[spierce7]

a fat framework has all the different cpu abis in it. Kotlin native gives you a gradle task to do that

[spierce7]

https://kotlinlang.org/docs/reference/mpp-build-native-binaries.html#build-universal-frameworks

[spierce7]

Then you basically zip up the framework, and do a github release with the .framework.zip file in the release files

[spierce7]

[Samuel Michael]

And then I suppose follow normal Carthage instruction for adding framwork zip from github repo?

[spierce7]

carthage can then point at the repository, and it will pull from the sem ver release tag from github

[spierce7]

if you look at what carthage pulls, it gives you the compiled frameworks - I think you find the unzipped farmework in there

[spierce7]

Carthage has a lot of limitations around this

[spierce7]

hope this helps though

[Samuel Michael]

Thanks 🙏 This is very helpful, hoping I can figure it all out

[spierce7]

I haven’t done this since q1 this year

[spierce7]

but I was able to figure it out both times pretty easily with the help of someone from my ios team who knew carthage

[spierce7]

oh - you know what it was!

[spierce7]

There was another way of releasing precompiled frameworks that I could never get working too. The Firebase iOS teams use it. You could try copying them

[Samuel Michael]

Cool I will try to get some help from some iOS devs on my team tomorrow

[Samuel Michael]

Thank you very much for your help

[spierce7]

This might help you too - https://github.com/Carthage/Carthage#archive-prebuilt-frameworks-into-one-zip-file

[spierce7]

OH - a few gotchas that I’m remembering

[spierce7]

I was creating the zip file with the gradle / java zip support - That didn’t work. carthage couldn’t unzip the file when I created a zip that way

[Samuel Michael]

Ah that is confusing, have to zip a certain way

[spierce7]

I had to use a mac specific zipping command. I never got the zip to work any other way

[Samuel Michael]

okay that is good to know

[dazza5000]

I need to do this today. Thank you for talking it through.

How do you build a framework that contains arm64 and x86 binaries?
