Hey everyone,

I've created a KMM library (with Android and ios targets) using the cocoapods plugin. This library imports an Obj C library via pod. The library compiles, and cinteropsObjCLibraryIos task works great.

Then I create another KMM project, and import the library project (in settings.gradle) and add the dependency to commonMain (implement(project(":myLibrary"))). When I sync and build for Android, everything works great, I even get code completion in iosMain.

But when I run for iOS, I get this error:

Task :MyLibrary:cinteropObjCLibraryIos FAILED
Exception in thread "main" java.lang.Error: /var/folders/26/l5zqw1v936l866mn2pwdy2j00000gn/T/7243334423362035241.m:1:9: fatal error: module 'ObjCLibrary' not found

Any ideas? I've been stuck for hours...

Did you have any progress with this?

[Osman Saral]

do you have m1 mac?

[Tiago Nunes]

Yes

[Osman Saral]

great 🙂 did you find anything on this?

[Osman Saral]

the cinterop builds success on terminal but not on xcode.

[Osman Saral]

i thought this was an issue with java version but i'm not sure

[Tiago Nunes]

Yes, this happened because I was running the cinterop task using an ARM JDK (OpenJDK Zulu ARM64). cinterop is not supported for M1 untill Kotlin 1.5.30

[Tiago Nunes]

Solution: Either update to Kotlin 1.5.30 or rerun the failing tasks through Rosetta. It should cache them, and build should work 🙂

[Osman Saral]

it was working before i use 1.5.30. I've update to kotlin 1.5.30 an now it doesn't 😄

[Tiago Nunes]

Then maybe your problem is that you’re using an Intel JDK?

[Tiago Nunes]

run java --version

[Osman Saral]

nope 😞
openjdk 11.0.12 2021-07-20 LTS

[Tiago Nunes]

Sorry, I can’t remember exactly how we solved it :s

[Osman Saral]

do you have iosSimulatorArm64 target on your build gradle?

[Tiago Nunes]

I do this in my build.gradle.kts:

val iosTarget: (String, KotlinNativeTarget.() -> Unit) -> KotlinNativeTarget =
    if (System.getenv("SDK_NAME")?.startsWith("iphoneos") == true)
        ::iosArm64
    else
        ::iosX64

iosTarget("ios") {}

cocoapods {
    summary = "Some description for the Shared Module"
    homepage = "Link to the Shared Module homepage"
    ios.deploymentTarget = "14.1"
    framework {
        baseName = "shared"
    }
    podfile = project.file("../iosApp/Podfile")
}

[Tiago Nunes]

Maybe try iosArm64("ios") instead?

[Osman Saral]

I also have the same targets 😕

[Osman Saral]

can you show me your java --version output?

[Osman Saral]

I downgraded to kotlin 1.5.21. it didn't work. I upgraded again to 1.5.30. and it dit work. 🤯

[Tiago Nunes]

Hm maybe try Build > Clean Project
