How do I add a dependency on a .framework to the iosTest target? Im getting an error ld: framework not found FirebaseCore in the task linkDebugTestIos

[Dominaezzz]

Use this arg -L/folder/where/framework/is/on/your/system

[Nick Williams]

Thanks @Dominaezzz how do I add that arg in the build.gradle?

[Dominaezzz]

The same way you did -framework FirebaseCore

[Nick Williams]

well thats added like this: https://github.com/GitLiveApp/firebase-kotlin-sdk/search?q=FirebaseCore&unscoped_q=FirebaseCore

[Dominaezzz]

Oh. You're consuming a library with framework dependency.

[Nick Williams]

Yes

[Nick Williams]

Test is here https://github.com/GitLiveApp/firebase-kotlin-sdk/blob/encode-defaults/firebase-auth/src/iosTest/kotlin/dev/gitlive/firebase/auth/auth.kt

[Dominaezzz]

I'm not entirely sure how to do this with iOS. You need to access linkerOpts in gradle, for Windows, Linux, etc it's in the executable block.

[Nick Williams]

And the firebase-auth module depends on the firebase-app module which is the one that has the FirebaseCore.framework dependency

[Dominaezzz]

This should help https://kotlinlang.org/docs/reference/building-mpp-with-gradle.html#configuring-binaries .

[Nick Williams]

We tried the below but didnt work:

binaries {
    getTest("DEBUG").apply {
        linkerOpts("-F$projectDir/../build/FirebaseAnalytics/FirebaseCore")
    }
}

[Dominaezzz]

You have -F instead of -L

[basher]

also that path looks kind of funny to me. try $buildDir instead of $projectDir/../build

[Nick Williams]

it works fine here https://github.com/GitLiveApp/firebase-kotlin-sdk/blob/encode-defaults/firebase-app/build.gradle.kts#L87

[Nick Williams]

Its because its in the top level build folder while $buildDir points to the submodule's build folder

[Dominaezzz]

rootProject.buildDir . The other just seems a bit.... bare.

[Nick Williams]

Updated, unfortunately doesn't fix the issue though

[Nick Williams]

Ok made good progress! had binaries {...} in sourceSets instead of kotlin 🤭, thanks both for your help!

@Nick Williams Hi Nick. I have the exact same problem. Trying to run linkDebugTestIos fails with ld: framework not found FirebaseFirestore. Can you share how you fixed it?

[Nick Williams]

i dont remmeber now but have a look in https://github.com/GitLiveApp/firebase-kotlin-sdk/

[Yaniv Sosnovsky]

do you mean the build.gradle file of the firebase app module?

[Yaniv Sosnovsky]

@Dominaezzz Hi, I saw your previous message in this thread, and I have the same exact issue, but I have no idea where my firebaseFirestore framework is.. can you please help?

[Dominaezzz]

Haven't touched this level of K/N for a while and idk about iOS. Try using find to find the framework.
