Hi everyone! Is there some up-to-date guide on how to use a Cocoapod in the iOS part of a shared module? Following this isn't even quite possible since apparently the syntax for pod() changed since it's creation. And if I extrapolate the instructions and simply add

pod("AFNetworking")

to the cocoapods section in build.gradle.kts, I get

> Task :shared:cinteropAFNetworkingIosArm64 FAILED
Exception in thread "main" java.lang.Error: /var/folders/4g/3s9scp9d5593dphx7n_7nhk40000gn/T/tmp1272859169392324213.m:1:9: fatal error: module 'AFNetworking' not found

I'm trying this in an KMMApplication template from AndroidStudio 4.1.1 running Kotlin Plugin 1.4.21-release-Studio4.1.1, in which I've only modified build.gradle.kts to add

kotlin("native.cocoapods")

to the plugins, changed the

ios {
…
}

block to

ios()

to get rid of the

Caused by: java.lang.IllegalArgumentException: Cannot create binary debugFramework: binary with such a name already exists

error that appears when adding the Cocoapods plugin and added this

cocoapods {
        pod("AFNetworking")
}

section. Am I missing something?

I would maybe try specifying version. The config error is

module 'AFNetworking' not found

. It's configured, but not finding that module for whatever reason. I'd also maybe try to build a regular iOS app in xcode with cocoapods to make sure that's working.

Hey Kevin, thanks for your input. I made sure to try this, specifying

pod("AFNetworking", "~> 4.0")

as the dependency. That didn't change anything for me. At the same time, if I'm adding the same dependancy to a regular iOS app, it is indeed working correctly.

Yeah, I did the same. Not sure what's going on with it.

version

,

summary

and

homepage

are required as well:

...
version = "1.0"

kotlin {
  ...
  cocoapods {
    summary = "Something"
    homepage = "<http://example.com|example.com>"
    pod("AFNetworking")
  }
}

Version can also come from the project version. I tried with a proper config and was still getting the issue.

I tested and worked for me.

Thank for for the suggestion, Jeff. I've just tried that and unfortunately, I'm still getting the issue as well.

Try changing

iosMain

folder to target-specific source sets(

iosX64Main

, 

iosArm64Main

, etc). Code comletion is missing in

iosMain

but compilation should work fine. https://youtrack.jetbrains.com/issue/KT-42319#focus=Comments-27-4417756.0-0

Hey Suleyman, thanks for the input. I tried renaming the

iosMain

folder in my

shared

Module to

iosArm64Main

and created a symlink to that named

iosX64Main

, so it now looks like attached. Unfortunately, that doesn't seem to help either. I've tried to open the example project referenced in YouTrack, but that doesn't work for me (even after removing the outdated version numbers of the specified plugins, the whole kotlin() section in

build.gradle.kts

remains red).

AFNetworking

works for me but I see this error when I try to use some other dependencies like

(CouchbaseLite-Enterprise)

. I'm using AS Canary version, so in my root build.gradle I have;

classpath 'com.android.tools.build:gradle:7.0.0-alpha03'

 // Touchlab build errors fails silently, making it hard to debug
 //classpath 'co.touchlab:kotlinnativecocoapods:0.12'

In my shared module build.gradle.kts I have the following;

import org.jetbrains.kotlin.gradle.plugin.mpp.KotlinNativeTarget
plugins {
    kotlin("multiplatform")
    id("com.android.library")
    id("org.jetbrains.kotlin.native.cocoapods")
}

cocoapods {
        summary = "..."
        homepage = "..."
        ios.deploymentTarget = "13.5"
        pod("AFNetworking")
        pod("Masonry")
       
    }

My project setup is still the just

ProjectName
--app
--shared
  --src
    --androidMain
    --iosMain
    --commonMain
--ios

It seems the issue with the CouchbaseLite-Enterprise pod may have to do with the dash in the name. I create a YouTrack for this. But you're having a similar problem with the AFNetworking pod, which is odd as this pod does work for us.

@Jeff Lockhart, could you maybe share a simple project based from the template that's configured to use AFNetworking? That would help me narrow down if the issue is related to my project config or the installed software.

@Marcus I think I have that installed, can you try to see if you can add this dependency

pod(CouchbaseLite-Enterprise)

if it works? I'm also having a similar error but not with

AFNetworking

@Marcus didn't get a chance to put together a sample project, but glad to hear you figured it out.

@chi Doesn't work for me, I get

CocoaPods could not find compatible versions for pod

during Gradle sync. In a normal Xcode project, I can include it just fine. Did you have the same issue?

Thanks for the test @Marcus. I'm getting this error

/var/folders/pv/3_5xn0dd0v5bf6sxbfcsq_wr0000gn/T/7009311365357251921.m:1:22: error: expected ';' after module name
	at org.jetbrains.kotlin.native.interop.indexer.UtilsKt.ensureNoCompileErrors(Utils.kt:152)
	...

@chi No idea about that. If you check that file at the specified line, what does it say there? (Not sure if you can access it after the fact, since it seems to be a temp file)

Ok, cool. I'll take a look, thanks

@chi After increasing the deployment target in my

cocoapods()

section, I now also get the same issue that you are getting. There's no temp file at the location specified.

Yeah, I agree. I think there's a bug with dependencies that have

-

because almost all dependency named as such doesn't work. There was a commit that tried to resolve this but I don't think it did. This is a serious issue I hope the Kotlin native team looks into

@chi I just had a look at their podspec and they specify another name for their

vendored_frameworks

. So if I try

pod("CouchbaseLite-Enterprise", moduleName = "CouchbaseLite")

it seems to proceed further with the compilation (but is hit with

Exception in thread "main" java.lang.IllegalArgumentException: 'CBLQueryMeta' is going to be declared twice

). Maybe you can go somewhere from there?

That's interesting, I've been getting that error only if I use their

CouchbaseLite

library, which is a different library from the enterprise, maybe this is just compiling that module which I assume is a dependency for

CouchbaseLite-Enterprisee

I think its what happens because if I change the moduleName to something else it returns the original error

Interesting, so it seems the cocoapods plugin seems to be conflating the pod name and the module name, which doesn't allow for them to be different.

I have no deeper insights, but they way I understand it, you give moduleName the same value you would use to

import

the module in a native project when for whatever reason this is different from the name of the pod.

That's helpful insight, thanks. Most of the KMM APIs lack detailed documentation.
