Hi there, I'm trying to import cocoapods library i...

Hi there, I'm trying to import cocoapods library in my k/n project, but following all available instructions, leaves me with unresolved import. I'm using cocoapods gradle plugin, add pods into cocoapods{}, generate podspec, add my podspec into podfile of ios project, make pod install, run workspace, build it, go back to android studio project and i have unresolved import :/

[Artyom Degtyarev [JB]]

Hello! Have you tried to “invaludate caches and restart”? If so, let’s check if .klib is actually presented an your project files. There should be something like <projectName>-cinterop-<podName>.klib .

[felislynx]

i can see them

[felislynx]

But still

import cocoapods.FirebaseFirestore

marks cocoapods in red

[Artyom Degtyarev [JB]]

Okay. What are the AS and Kotlin plugin versions here?

[felislynx]

AS 3.5.3

[felislynx]

and 1.3.61 for kotlin

[felislynx]

the issue is not importing my k/n library as pod into xcode, but using for example FirebaseFirestore pod in iosMain in kotlin native

[Artyom Degtyarev [JB]]

I understand. Under Kotlin plugin I meant the IDE plugin, not the gradle one. It might be outdated a bit, and therefore unable to interpret KLIB contents correctly. Please check it and post here, ok?

[felislynx]

v1.3.61-release-Studio3.5-1

[felislynx]

i think this is latest plugin version from stable channel

[Artyom Degtyarev [JB]]

Correct. I’m trying to reproduce it locally now, as soon as I’m sure the setup is the same.
Also, maybe this(https://github.com/touchlab/FirestoreKMP) library can be interesting for you.

[felislynx]

seen it 🙂 this was place where i first saw, i could use cocoapods in kn, unfortunately even this project produces same result, unresolved import 😞

[felislynx]

I've also tried this approach: https://medium.com/swlh/kotlin-multiplatform-ios-frameworks-dependencies-2320ca13ea30

[felislynx]

also without success

[Artyom Degtyarev [JB]]

Hmm. I just followed all steps you mention, and in this case
import cocoapods.FirebaseFirestore.*
seems to resolve correctly. Have you tried to invalidate caches? For now, I’m kinda out of ideas here.

[felislynx]

yes, i've tried to invalidate caches

[felislynx]

maybe try to list all steps you did, i think this might be a one little thing that prevents it from working, one that noone is mentioning because it might to be obious

[Artyom Degtyarev [JB]]

Ok, I am 99% sure you made everything correct, but here it goes.
• I took a sample project, that you probably saw it (https://stackoverflow.com/questions/60126503/how-to-add-thirdparty-ios-pod-library-into-kotlin-native-project-getting-error/),
• Added pod("FirebaseFirestore") line in the SharedCode/build.gradle.kts , cocoapods section.
• Then executed :SharedCode:podspec, opened Xcode project and built it.
• After that, in the Android Studio added import as above into the SharedCode/src/iosMain/kotlin/actual.kt file.

[felislynx]

hmm

[felislynx]

i'm not using .kts build files

[felislynx]

maybe this is whats wrong

[felislynx]

i'll try kts tommorow and let you know of result

[felislynx]

thank you 🙂

[felislynx]

So, checked out this project, added pod line as you, generated podspec, done pod install and tried to build

[felislynx]

/Users/lynx/Library/Developer/Xcode/DerivedData/KotlinIOS-fdgjjjppacwrrnfxaylegnufjofy/Build/Intermediates.noindex/KotlinIOS.build/Debug-iphonesimulator/KotlinIOS.build/Script-47729E7122F480EB00B9B36B.sh: line 4: cd: /Users/lynx/Workspaces/Tests/mpp-ios-android/native/KotlinIOS/../../SharedCode/build/xcode-frameworks: No such file or directory
/Users/lynx/Library/Developer/Xcode/DerivedData/KotlinIOS-fdgjjjppacwrrnfxaylegnufjofy/Build/Intermediates.noindex/KotlinIOS.build/Debug-iphonesimulator/KotlinIOS.build/Script-47729E7122F480EB00B9B36B.sh: line 5: ./gradlew: No such file or directory

[felislynx]

this wasn't the case before (with non .kts) build

[Artyom Degtyarev [JB]]

Do those directory and file actually exist? I mean, /Users/lynx/Workspaces/Tests/mpp-ios-android/native/KotlinIOS/../../SharedCode/build/xcode-frameworks and /Users/lynx/Workspaces/Tests/mpp-ios-android/gradlew . If not, please try to execute :SharedCode:packForXcode task manually, at least it should create the xcode-frameworks directory.

[felislynx]

ok, so after step packForXcode
> Configure project :SharedCode
Kotlin Multiplatform Projects are an experimental feature.

> Task :SharedCode:generateDefAFNetworking UP-TO-DATE
> Task :SharedCode:cinteropAFNetworkingIos FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':SharedCode:cinteropAFNetworkingIos'.
> Cannot perform cinterop processing for AFNetworking: cannot determine headers location.

 Probably the build is executed from command line.
 Note that a Kotlin/Native module using CocoaPods dependencies can be built only from Xcode.

[felislynx]

this is xcode fail log

[Artyom Degtyarev [JB]]

Have you adjusted Framework Search Paths in your project?

[felislynx]

To be sure i done it right

[felislynx]

under framework Search Paths i have Debug and Release

[felislynx]

under debug i hit little + button

[felislynx]

and just write $(inherited)

[felislynx]

clean, build, same result

[felislynx]

i know, it is experimental feauture, but damn, it is hard to use

[Artyom Degtyarev [JB]]

Okay, can you look at this patch? That’s all of my edits.

workingSample.patch

[felislynx]

applying and testing...

[felislynx]

AFNetworking resolved

[felislynx]

in imports

[felislynx]

but FirebaseFirestore not o_O

[felislynx]

i'll try to invalidate caches and restart studio

[felislynx]

works!

[felislynx]

inherited should be in framework search paths and header search paths?

[Artyom Degtyarev [JB]]

I think so. In my case, it was there already.
You know, usually cocoaPods plugin is much less pain, especially using it from the Xcode side.

[felislynx]

Yeah, i'm trying to apply necesary changes to my project and i'll let you know if i succeeded, maybe we could then send info to jetbrains to update their readme 😉

[felislynx]

It's alive! (i mean, it's working!) 😄

[felislynx]

thank you very much for all your help

[felislynx]

it looks like, .kts is required

[felislynx]

it won't work on normal gradle file

[felislynx]

one last question, what should i add to .kts to have in androidMain access to Android libraries?

[Artyom Degtyarev [JB]]

Well, have a look at this doc(https://kotlinlang.org/docs/reference/building-mpp-with-gradle.html#android-support). Basically, you’ll need to add a plugin to your script, and then use android() target instead of jvm("android") . And then, your android source sets will become Android-styled(I mean, all this main, debugMain, etc instead of <targetName><Main | Test>, so the dependencies section will need some adjustments.

[felislynx]

ok, thank you
