Hi! Created a new project with 2 gradle modules, both KMM (1.7.20) and when I add dependency I see this warning. Everything compiles fine, but I'd still like to resolve this warning somehow:

I'm working on a KMM library, using cinterop and having some issues when I export my library to a framework 🧵

Has anyone seen issues with unit testing and codesigning? I am seeing this error when running unit tests on my M1 Mac running macOS 13.1:

> Task :Shared:macosArm64Test FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':Shared:macosArm64Test'.
> command '/Users/conradev/Projects/Wallet/Shared/build/bin/macosArm64/debugTest/test.kexe' exited with errors (exit code: 137)

and the corresponding log in the system log is generated:

default	14:14:45.212066-0800	kernel	ASP: Security policy would not allow process: 43402, /Users/conradev/Projects/Wallet/Shared/build/bin/macosArm64/debugTest/test.kexe

How would I set up Gradle to build a multiplatform native library? (i.e. wasm for JS, native with JNI for Android + desktop, etc)

Hi all. I'm running into issues when exporting my sealed types across multiple modules. For example, my module setup is

:app
⎿:feature-1
⎿:feature-2

:app

is the only module I'm depending on from iOS, but I am exporting my feature modules. I can export sealed types from

:app

just fine

sealed class AppSealedType {
  object AppTypeA: AppSealedType()
  object AppTypeB: AppSealedType()
}

And they do show up on the swift side. However, when I define a seal type on one of the

:feature-x

modules

sealed class FeatureSealedType {
  object FeatureTypeA: AppSealedType()
  object FeatureTypeB: AppSealedType()
}

Only the top seal interface is exported. I can trick the tooling to "force" export the sealed child types by referencing them in the

iosMain

of the

:app

as a workaround

val FeatureTypeA = FeatureSealedType.FeatureTypeA

When I do that, the child types are exported Is this a known bug/limitation? Is there a way export all child types of my sealed types? More details in the 🧵

Hi Folks! Is there a way to tell a KMP project to NOT fetch a common dependency for a particular platform For example, this dependency:

implementation("dev.icerock.moko:kswift-runtime:0.6.1")

is only available for KMM but my project supports Android, iOS, and Web as well. So can I instruct KMP to not fetch its deps for JS?

Cross posting for visibility. If anyone could point me in the right direction, I'd really appreciate it. https://kotlinlang.slack.com/archives/C19FD9681/p1671824807177329

WorldWindKotlin - the first Kotlin multi-platform 3D GIS update 1.1.5 released https://github.com/WorldWindEarth/WorldWindKotlin/releases/tag/v1.1.5

Is it possible to develop a KMM library and app in tandem? I mean is there a workflow where I can make changes to the library, make corresponding changes to the app, and build & run to test? Or must I first publish my library changes (to MavenLocal for example), update dependencies in my app, make my app changes, and only then can I build and test?

Is there a reason why

jvmMain

source set access is not provided by Kotlin DSL (unsure how this works…)? For example, following:

kotlin {
  android()
  jvm()

  sourceSets {
    val commonMain by getting {
      // ...
    }
    
    val androidMain by getting {
      // ...
    }
    
    val jvmMain by getting {
      // ...
    }
  }
}

Can be replaced with this, except for

jvmMain

:

kotlin {
  android()
  jvm()

  sourceSets {
    commonMain {
      // ...
    }

    androidMain {
      // ...
    }

    // `jvmMain` extension is not provided
    val jvmMain by getting {
      // ...
    }
  }
}

Has anyone tried out korge for multiplatform gaming? Do you have any thoughts on how complete / ready for production it is?

Hello and Marry Christmas 🎄 I have an issue where adding a kmm module (i.e domain) module to shared module results with Prefix added to the generated iOS classes, for example User class under domain will be DomainUser in iOS How can I remove this prefix in build.gradle Thanks

Hi folks Merry Christmas 🎄 I've been facing this same error: https://stackoverflow.com/questions/70632359/using-kmm-shared-library-for-use-in-xcode-gives-several-warnings-and-errors-when Unfortunately, there are no responses on this SOF post. Could we please have a look at it?

Has anyone tried https://github.com/korlibs/kproject before? It basically seems like carthage for kotlin. If it actually does what it sounds like... being able to publish libraries while not having to mess with maven central... that'd be amazing...

Hi! Can you please tell me how to delay the response? On coroutines, I would do something similar.

can I use ktor logger in shared module in kmm ?

Hi everyone. I’m trying to config the new KMM project. We have a plan to make both the android and iOS versions, but the iOS app should be started after the android app is done. So the issue is: - I remove all configs about the native target in the Gradle build file (please take a look at the picture below). - If I delete the part from 11-19, the androidMain can not see commonMain. - On the other hand, if I keep it, the “expect” function will complain that I have no “actual” implementation in iOS. I want to declare all “expect” functions and implement them in android first. After that when my team has an iOS developer I will implement it in iOS. Please help me. Thanks in advance.

I'm trying out Android Studio 2022.1.1 RC3 and it seems like the KMM plugin 0.5.1 isn't able to start iOS tests from within the IDE. I only get this in the logs:

FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':shared-br-network:iosSimulatorArm64Test'.
> No value present

If I open the project in 2021.3 everything works as expected, also when I use

./gradlew :shared-network:iosSimulatorArm64Test

Did somebody experience the same and has a solution?

I wrote a test in commonMain, it uses

= runTest

and internally it uses

GlobalScope.launch

but this call is blocking forever and the callback I'm passing to it doesn't ever run, how can I debug this?

Updating MPP module to Kotlin 1.8.0, trying to get rid of this new warning:

Multiplatform/Android-V1-SourceSetLayout: Multiplatform/Android-V1-SourceSetLayout is deprecated...

I add it then I get new warnings:

Multiplatform/Android-V2-SourceSetLayout: Usage of 'Android Style' source directory

are there any docs on this new V2 layout. Migration guide perhaps?

And thank you so much for fixing this issue: https://youtrack.jetbrains.com/issue/KT-47355 My gradle file is sooo much cleaner without the workaround in there...

In Kotlin Multiplatform for Mobile, how we can write unit test to check intermediate values of

KLiveData

, can anyone give an example ?

is there any way so that we can add dependencies like for firebase in shared dependency and write code for multiple platform in single go

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.

Hello, trying to follow the guide on making a KMM app with cocoapods with some basic networking, but when I try to

Hello K friends, What if Node were more than just JS? To celebrate the new year, I am pleased to share a new project called Elide, a new server runtime, like Node or Deno, but polyglot, written in Kotlin and based on GraalVM. We are in alpha and very open to early feedback and contributions for anyone interested, over in #framework-elide 🥳 You can do wild things with it, like fast React SSR in Micronaut or Spring. Guest language support is starting with JS, but there are plans to integrate other languages like Python, Ruby, and Rust/Go/etc. via LLVM. Of course,

native-image

is supported out of the box. • 🚀 Trying it out

curl -sSL --tlsv1.2 dl.elide.dev/cli/install.sh | bash -s -

👆 the one liner works on Darwin (amd64/arm64), and Linux (amd64) so far.

If you prefer NPX:

npx @elide-dev/elide@alpha shell

K Building Kotlin apps with it • Elide can be used as a plain library with a regular Micronaut server, and Ktor support is on the way. There are Maven artifacts in a custom repository which is easy to use during the alpha; you can see a sample here. • G Gradle plugin You can easily install the Gradle plugin to build your frontend assets and your Kotlin/JS, and package it into your server binary. It will handle building for SSR and CSR both, so you can easily switch between browser rendering modes. Check it out here. Maven and Bazel support are planned. • 🖥️ Using the shell

elide shell

drops you into a shell just like Node (see attached screenshot), the difference being the

URL

class we're using here is implemented in Kotlin, backed by the road-tested power of Micronaut, KotlinX, Netty, and the Java standard library. It has simply been adapted for use in JavaScript, according to the WhatWG URL Spec. • js Use Kotlin/JS or regular Node stack Elide packages and consumes your JS/TS with built-in support for

esbuild

, so you can use a standard Node toolchain or the Kotlin/JS stack. • 💨 Super fast React SSR Because Elide is basically Kotlin with a super-fast JS runtime attached, it can do JS SSR without leaving the JVM. This can soon be drop-in compatible with many React apps. You can see a live sample here to confirm it is fast and server-rendered. The code for that sample is pasted below to show how simple it is to call back and forth between Kotlin and your React app:

@Page class Index : PageWithProps<YourProps>(YourProps.serializer()) {

    // Serve React SSR.
    @Get("/") suspend fun indexPage(request: HttpRequest<*>) = ssr(request) {    // 1: tell the server we're going to do SSR for this request
      head {
        title { +"Hello, Elide!" }
        stylesheet("/styles/base.css")
        stylesheet("/styles/main.css")
        script("/scripts/ui.js", defer = true)   // <-- 2: serve the CSR bundle so it can hydrate the react SSR response
      }
      body {
        injectSSR(this@Index, request)    // <-- 3: execute the JS VM to produce the SSR response, and splice it into the server response
      }
    }

}

• 🐙 Contributors needed The future of software is much more polyglot than today's paradigm: developers love to fight about frameworks, but at the end of the day, we're all writing code, and eliminating barriers between languages means easier collaboration and more value for all of us. It shouldn't be a Node vs. The World or a Rust vs. The World argument; we should get to pick and pull the best code we want from anywhere and use it to build our apps, especially from a multi-platform language like Kotlin. This runtime and framework are designed for that future. *If you agree, join us and make a dent in the universe*; you'll have a chance to be impactful and shape a brave new idea from the ground up. • 🙏 Thank you We chose Kotlin because of the fantastic community. 2023 will be a massive year for Kotlin, and we think that betting the farm on it is reasonable and smart. We are super excited about what JetBrains and Kotlin have in store for us with K2, context receivers, value classes... just so much to look forward to. Cheers and happy new year, Kotlin devs, K sam Slack Conversation
