I have a KMP project for Android & iOS with a shared umbrella module and a bunch of submodules, all with cocoapods integration.

An example of dependency chain is: app -> shared umbrella module -> moduleA -> moduleB
Now if moduleB declares a pod dependency towards FirebaseCrashlytics for example, I find that I have to also declare that dependency in the shared umbrella module, otherwise I get a symbol not found error when building the iOS app.

Furthermore, if I run the iOS unit tests from moduleA (that imports moduleB), I also have to declare the pod dependency for Crashlytics in moduleA.

Is this expected behavior? Can I somehow declare the pod dependency in moduleB and then export the module with all its pod dependencies?

You might be able to add
"use FirebaseCrashlytics"

to the module.modulemap to tell Xcode which associated frameworks are "safe" to cross-reference, without getting the cross-framework import errors.

I haven't tried this, but I do use a custom modulemap in my own frameworks to acheive the same > shared umbrella module -> moduleA -> moduleB configuration.

framework module ServiceCore {
umbrella header "ServiceCore.h"
export *
module * { export * }

framework module ServiceCommon {
umbrella header "ServiceCommon.h"
export *
module * { export * }
}

link framework "UIKit"
link framework "SystemConfiguration"
link framework "CoreGraphics"
link "System"
link "sqlite3"
link "z"

use AnalyticsCommon
}

awesome. thanks. I will try it

for the record, I managed to fix this using the linkOnly flag for the pods that don't require cinterop bindings (the ones that are linked in intermediary modules).
