hi,
I'm experimenting with referencing a KMM framework from within an iOS framework,
I'm running ./gradlew :shared:embedAndSignAppleFrameworkForXcode script at pre-compile time on the framework's project file and
I'm getting this runtime error:
dyld[87584]: Library not loaded: @rpath/shared.framework/shared

I'm following this documentation https://kotlinlang.org/docs/multiplatform-mobile-integrate-in-existing-app.html#connect-the-framework-to-your-ios-project

does anyone know what other build settings I'm missing here?

A couple of things could be wrong:
• maybe the search path in the build settings in your Xcode project is not correct
• maybe you are using a dynamic framework and the file can not be found after the project has been build. You would need to write a script to copy the binary manually to the correct place then
Try to make the framework static in your build.gradle file. This could solve it.

[kpgalligan]

Not sure. We pretty much never use the embed task. Just Cocoapods/SPM

[Konstantin Tskhovrebov]

@Cristina Suciu could you explain what you want to build?
and show your build config
the error says: your dynamic framework wasn’t found in rpath which usually points inside app bundle.
the embed task copies framework to an app dir during a xcode build

[Cristina Suciu]

@Konstantin Tskhovrebov I have a custom iOS framework that is running the embedAndSignAppleFrameworkForXcode at pre-compile time. I can create a sample project and I'll share it with you

[Konstantin Tskhovrebov]

kotlin framework is dynamic then you have to embed it together with your iOS framework to result app

[Cristina Suciu]

@Konstantin Tskhovrebov how do I embedded it? I've used xcodegen to add the kmm framework as a dependency, but it fails at compile time. The custom script executing embedAndSignAppleFrameworkForXcode is ran later in the build process.

[Cristina Suciu]

@kpgalligan <<Just Cocoapods/SPM>> do you just run the script to generate the KMM framework from terminal? Or do you integrate it in some other build process?

[kpgalligan]

The default Cocoapods setup lets you build from Xcode and it handles the gradle calls to properly wrap things. The Android Studio template has a Cocoapods option (IIRC), or you can look at our basic sample: https://github.com/touchlab/KaMPKit

@Konstantin Tskhovrebov I'm following up on my attempt to embed a KMM framework into an iOS native framework, here's my fork of the kmm-production-sample repo https://github.com/Kotlin/kmm-production-sample/commit/8c22b421478dbd775e602acb215bbc33089cc197 How can RssReader KMM framework be embedded into the iOS framework using only the embedAndSignAppleFrameworkForXcode gradle task?

How can RssReader KMM framework be embedded into the iOS framework using only the embedAndSignAppleFrameworkForXcode gradle task?

there is no way, i think. 🤔
because this is a task for embedding a dynamic framework to a resulting application.
try to build a XCFramework from the kotlin project and use it on the Xcode side
