I’m having a very similar problem like the one described above, but with the different dependency (Ably). My gradle sync fails on cinterop task (shared:cinteropAblyIos to be specific) with the message:

Exception in thread "main" java.lang.Error: /var/folders/2q/gjhd6ng16j51tnmw772w02k40000gp/T/5129966869508006261.m:1:9: fatal error: could not build module 'Ably'

I tried to check whether I’m able to import some other cocoapods dependency and for example I can import AFNetworking and use it, but when I try to import Ably it doesn’t work
What is the reason it fails? It’s something wrong with the dependency itself?

[KamilH]

cocoapods {
    summary = "Some description for the Shared Module"
    homepage = "Link to the Shared Module homepage"
    ios.deploymentTarget = "14.1"
    frameworkName = "shared"
    pod("Ably") {
        version = "~> 1.2"
    }
    podfile = project.file("../iosApp/Podfile")
}

What's your kmm version and cocoapods version?

[KamilH]

I’m using Kotlin 1.5.30 and the same version for both multiplatform and cocoapods plugins

@KamilH put this in your build.gradle and see if it helps:

extraOpts = listOf("-compiler-option", "-DNS_FORMAT_ARGUMENT(A)=")

You should also probably update to Kotlin 1.5.31, there was at least one cinterop bugfix in there that I know of.

[KamilH]

Thanks @matej for suggestion, but it didn’t help in my case. I updated to Kotlin 1.5.31 and tried to add the dependency like that:

pod("Ably") {
    version = "~> 1.2"
    extraOpts = listOf("-compiler-option", "-DNS_FORMAT_ARGUMENT(A)=")
}

and I’m still getting the same error. I also updated to the latest XCode (13.0, before I was on 12.5) version and still the same

[matej]

@KamilH can you try doing it like this directly in the cocoapods block:

cocoapods {

        tasks.withType(org.jetbrains.kotlin.gradle.tasks.CInteropProcess::class.java) {
            settings.compilerOpts("-DNS_FORMAT_ARGUMENT(A)=")
        }
    }

[KamilH]

I just tried, but unfortunately it didn’t help as well

[matej]

Sorry I couldn't help. It's probably worth for you taking a look at issues mentioning cinterop in Kotlin's issue tracker: https://youtrack.jetbrains.com/issues?q=project:%20Kotlin

If you don't find anything that helps move forward, you can create a new issue and attach a small reproducer project. They're pretty responsive over there.

I was able to resolve this by also adding this to my gradle.properties

kotlin.mpp.enableCInteropCommonization=true

as well as the above mentioned compiler option

[Brendan Goldberg]

though it only fixed my issue because all of my iOS code is inside the iosMain directory

[Brendan Goldberg]

and I'm guessing this links the iosX64 and iosArm64 cinterops to iosMain

[KamilH]

Thanks Brendan, I’m already using this settings (I’m using hierarchical project structure), but thanks for the suggestion
Matej, I already posted my case here and I hope it will let Kotlin’s team identify the problem easier

cocoapods {        
        pod("msgpack", "0.4.0")
        pod("AblyDeltaCodec", "1.3.1")
     // pod("Ably", "1.2.6")
}

I have try add dependencies on msgpack and AblyDeltaCodec , it is successful.
but add Ably then got same error:`cinteropAblyIosArm64 FAILED. fatal error: could not build module 'Ably'`
