I'm new to KMP-NativeCoroutines and am not sure if I'm doing something wrong here - above is the error excerpt from running ./gradlew :shared:embedAndSignAppleFrameworkForXcode --info as a build phase in my iOS app. Any help would be appreciated.

KMP-NativeCoroutines version: 1.0.0-ALPHA-38 KSP version: 2.1.0-1.0.29 MacOS version 15.2 (Sequoia), Apple M2 chip XCode Version 16.2 (16C5032a)

Sounds like there is an issue with the ~/.konan directory similar to this issue.

Could you try to sync in IntelliJ/Android Studio and/or clearing the konan directory?

[Saad-Mufti]

I tried that, to no effect.

I am having a similar issue where cocoapods doesn't recognize [1.0.0-ALPHA-38], only up to ALPHA-5 version, but when i reduce the plugin in Kotlin to ALPHA 5 i see a similar error for kotlin 2.1.0.

Does alpha-5 work for kotlin 2.1.0?

[rickclephas]

@chromecountry no Kotlin 2.1.0 is only supported in 1.0.0-ALPHA-38

@rickclephas when I add the following to my pod file:

  # Pods for iosApp
  pod 'KMPNativeCoroutinesAsync', '1.0.0-ALPHA-38'    # Swift Concurrency implementation
  pod 'KMPNativeCoroutinesCombine', '1.0.0-ALPHA-38'  # Combine implementation
  pod 'KMPNativeCoroutinesRxSwift', '1.0.0-ALPHA-38'  # RxSwift implementation

I get this error:

alex@anothergreenworld iosApp $ pod repo update

None of your spec sources contain a spec satisfying the dependency: `KMPNativeCoroutinesRxSwift (= 1.0.0-ALPHA-38)`.

You have either:
 * out-of-date source repos which you can update with `pod repo update` or with `pod install --repo-update`.
 * mistyped the name or version.
 * not added the source repo that hosts the Podspec to your Podfile.

When I check cocoapods.org I do not see ALPHA-38 available

[rickclephas]

@chromecountry there is an issue with the RxSwift CocoaPods publication that I am looking into. If you don't need the RxSwift support you can just remove it. Otherwise you could try to use the Swift Package Manger for now.

[chromecountry]

@rickclephas Thank you. It'd be simpler to not have to migrate away from cocoapods / kotlin 2.1 for my project. Do you have an ETA on when we can expect the CocoaPods publication to be fixed? I am ok to wait if this will only take a few days.

[rickclephas]

@chromecountry no ETA, but hopefully soon.

[rickclephas]

@chromecountry I am afraid a CocoaPods issue prevents the release of the RxSwift implementation (see https://github.com/CocoaPods/CocoaPods/issues/11839 and https://github.com/CocoaPods/CocoaPods/issues/12033).

As a workaround you can request CocoaPods to just get the spec from the repo instead:

pod 'KMPNativeCoroutinesRxSwift', git: 'https://github.com/rickclephas/KMP-NativeCoroutines.git', tag: 'v1.0.0-ALPHA-38'

Just ran into the error mentioned in the original error above, here: https://github.com/Kotlin/KMP-App-Template-Native/pull/30

java.lang.ClassNotFoundException: org.jetbrains.kotlin.cli.utilities.MainKt

In my case it seems to be caused by https://youtrack.jetbrains.com/issue/KT-74278/KSP-tasks-dont-trigger-a-K-N-distribution-downloading

And a possible workaround is disabling native toolchains in gradle.properties until you get the fix for the above in 2.2.0-Beta1:

kotlin.native.toolchain.enabled=false
