Hello nice people,

I am trying to use iOS Firebase dependency in KMM through CocoaPods ( https://kotlinlang.org/docs/native-cocoapods.html#add-dependencies-on-pod-libraries ) and I am getting:

The /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/ld command returned non-zero exit code: 1.

output:

Undefined symbols for architecture arm64:

"_OBJC_CLASS_$_FIRStorage", referenced from:

objc-class-ref in result.o

ld: symbol(s) not found for architecture arm64

Any idea where to go from here?

M1 / simulator?

[Martin Rajniak]

Yes running simulator on M1

[Michal Klimczak]

you either need to run xcode on rosetta which will make your simulators run as x86_64 or make your shared.framework compatible with arm64 simulator which might not be possible yet (lots of libraries are not compatible with apple silicon yet).

I usually either run on physical device or directly on mac.

regarding "making shared.framework compatible with arm64 simulator"

how can I do that?

before adding the Firebase dependency to shared code, it worked on M1,
and if I add the Firebase dependency directly to iOS app, it also works,
so it seems that the issue is somehow connected to using the iOS dependency in shared code.

Hey @Martin Rajniak, were you able to solve that? I’m getting the same exact error. I’m not on M1, though.

[Martin Rajniak]

Unfortunately no - but not sure why this would be an issue outside of M1.
