ios – shared module binary of Kotlin Multiplatform App not packaged by fastlane

we are facing an issue with our CI/CD builds using fastlane on iOS for quite some time and I am now trying to resolve this issue.

We are developing a Kotlin Multiplatform app that has the shared module packaged via Cocoapods, which works great during development and even Archiving and releasing via XCode.

The CI/CD build using fastlane also works fine, the app is sucessfully build and published to App Center as ad-hoc release. However when I try to open the App on device it crashes right away. Checking the device logs I see this error:

ASI found [dyld] (sensitive) 'Library not loaded: @rpath/shared.framework/shared
Referenced from: <1BD25F02-DE04-35D4-BE94-37A6A7D3A268> /private/var/containers/Bundle/Application/B78CBDBE-5C0D-45E9-9CE9-E55D1A56166D/iosApp.app/iosApp
Reason: tried: '/usr/lib/swift/shared.framework/shared' (no such file, not in dyld cache), ...

I searched the web for solutions, however until now nothing pointed me into the right direction, so I hope someone can help me out.

Podfile:

target 'iosApp' do
  use_frameworks!
  platform :ios, '16.2'
  pod 'AppCenter'
  pod 'MaterialDesignSymbol'
  pod 'SwiftLint'
  pod 'shared', :path => '../shared'
end
