Hey folks, I am trying to use `native.cocoa` plugin as described here: <https://kotlinlang.org/docs/...

# multiplatform

Hey folks,
I am trying to use native.cocoa plugin as described here:
https://kotlinlang.org/docs/native-cocoapods.html#install-the-cocoapods-dependency-manager-and-plugin

I’m just trying the code snipped from the docs to use AFNetworking inside iOSMain (as described in the docs).

kotlin {
   ...
    cocoapods {
        summary = "Some description for the Shared Module"
        homepage = "Link to the Shared Module homepage"
        ios.deploymentTarget = "14.1"
        frameworkName = "sharedClient"
        podfile = project.file("../iosClient/Podfile")

        pod("AFNetworking") {
            version = "~> 4.0.1"
        }
    }
    ...
}

The problem I am facing right now is that cinteropAFNetworkingIos fails:

> Task sharedClientcinteropAFNetworkingIos Exception in thread “main” java.lang.Error: /var/folders/n9/5pkml05d7mn3xzdyty8cx5380000gn/T/3707914287112298431.m19: fatal error: could not build module ‘AFNetworking’

I think it is more of a cocoa pods issue on my local machine, but I don’t really know how cocoa pods works exactly under the hood. I think cocoa pods did not download AFNetworking.

(In a plain iOS / xcode project (not kotlin multiplatform app) I have used successfully cocoa pods, so I think it is fair to assume the required cocoa pods gems are installed on my machine.)

Could anyone please point me in the right direction?

Make sure you have the cocoapods-generate gem installed. This isn't normally required for using CocoaPods with a non-KMM iOS app.

I've seen a similar error before where both cocoapods and cocoapods-generate were installed. After uninstalling and reinstalling them both it fixed the issue.

Note, frameworkName is deprecated. You should replace it with:

framework {
    baseName = "sharedClient"
}

[Hannes]

Thanks for your answer. I have cocoapods-generate installed.
I also tried to sudo gem uninstall ... both gems and reinstall them, but didnt help 😞

ok, looks like with kotlin 1.6.0 it works but with kotlin 1.5.x it doesnt … I don’t want to use 1.6.0 yet because of the recently discovered issues, I guess I will wait for 1.6.10

[Viacheslav Kormushkin]

This is probably because of Xcode 13, which is fully supported in 1.6.0 only. if you’d like to stay on 1.5.3 for a while then downgrade Xcode to 12.5 as well

[Jeff Lockhart]

You can also get Xcode 13 working with Kotlin 1.5.31 by adding this to your build.gradle.kts:

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

[Viacheslav Kormushkin]

Yeah, right, this is also an option
