Hi everyone 👋
I am trying to add DataDog library in iosMain part of the KMM project.
But Somehow I can not import the library into Kotlin file.
Here is the ticket that I opened yesterday.
https://youtrack.jetbrains.com/issue/KT-55687/Can-not-add-DataDog-Dependency-via-CocoaPods-in-Kotlin-Multiplatform-Mobile-Project
I really appreciate if you guide me. Thanks.

Have you tried installing the pod?

[Hakan]

In build gradle you don't have to call command pod install . But you have to sync gradle file since my intention is to use in KMM project.

[Hakan]

And I installed the pod in a Xcode project and it was working fine.

If DataDog is a pure Swift library, this could be a reason why the interop isn't working as expected.

[darkmoon_uk]

I see the SDK offers some explicit ObjC compatibility feature

[darkmoon_uk]

You'll need to be using this for Kotlin/Native interop

[Hakan]

Hi Chris,
Sorry but I couldn't understand your last message.
What should I do with Kotlin/Native interop? Do I have to write some wrapper class in Kotlin?

[darkmoon_uk]

It's notable that CocoaPods hosts both a DataDogSDK and a DataDogObjC

[darkmoon_uk]

...suggesting that the non-ObjC one is pure Swift ABI - Kotlin Native won't be able to interop with this

[darkmoon_uk]

try using the DataDogObjC one.

[Hakan]

Yes. I used the ObjC one but then I couldn't import the library.

[Hakan]

Ok We have finally managed to make it work using the 'proxy'(DDLog) framework.
Because DataDogObjCSDK we giving error when doing a gradle sync

This is the cocoapods configuration:

cocoapods {
        summary = "Common library for mobile project"
        homepage = ""
        version = "1.0"
        ios.deploymentTarget = "11.0"
        framework {
            baseName = "MultiPlatformLibrary"
            linkerOpts.add("-lsqlite3")
            isStatic = false
            transitiveExport = true
            export(Deps.kermit)
            export(Deps.Moko.mvvm_api)
            export(Deps.Moko.resources)
        }
        /*
        pod("DDLogg") {
            moduleName = "DDBridge"
            source = git("<https://github.com/aneeshzed/DDLogg.git>") {
                tag = "0.1.7"
            }
        }*/
        pod("DatadogSDKObjc") {
            version = "~> 1.14"
            moduleName = "Datadog"
        }
        pod("DatadogSDK") {
            version = "~> 1.14"
            moduleName = "DatadogObjc"
        }
        xcodeConfigurationToNativeBuildType["Pilot"] = org.jetbrains.kotlin.gradle.plugin.mpp.NativeBuildType.DEBUG
    }

And this is the error that we get:

[Mukesh]

I was also getting same error , solved by this:

tasks.named<org.jetbrains.kotlin.gradle.tasks.DefFileTask>("generateDefDatadogObjc").configure {
    doLast {
        outputFile.writeText("""
            language = Objective-C
            modules = Datadog DatadogObjc
        """)
    }
}

@Mukesh Where did you add this code?

[Mukesh]

@Sonny at the end of your module’s gradle file
