[FR] How to build Catalyst universal #1134

I'm trying to build a Firebase C++ library for Catalyst. I see in apple.toolchain.cmake that supports 2 platforms:

MAC_CATALYST: x86_64
MAC_CATALYST_ARM64: arm64

But in the available libraries (darwin, ios, tvos) I see the universal folder. So, can I ask how to build a library that supports all archs?

I found a few problems with this issue:

I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.
This issue does not seem to follow the issue template. Make sure you provide all the required information.

I'm not 100% sure what the differences are between Catalyst and other types of Mac builds, but generally the universal libraries contain symbols for both x86_64 and arm64, and would likely be what you need to use. You could also try linking directly against the source code, if your project is configured for that.

Hi @b0f1df79,

The toolchain file that you've linked was borrowed from another open source project and has more features than what the Firebase C++ SDK currently uses. Our underlying dependency of the Firebase iOS SDK has beta support for Catalyst but we currently don't build and test against it.

I'll add this as a feature request. Everyone, please upvote this ticket if this is something you're interested in. Thanks!
