Hi All, I noticed in the docs that pure swift dependencies aren't supported.

Pure Swift modules are not yet supported.

I reached for SwiftSoup for a particular requirement I'm working on, but it was unusable for this reason. However, I noticed the yet in there. I searched the kotlin issue tracker for an issue I could follow for updates and didn't find one. Is this an eventual goal of the KMM and/or Kotlin/Native toolchains? Did I miss an issue? This seems like something that would benefit KMM use-cases a lot, but I'd be interested in reading about technical difficulties or progress.

Hi guys, i’m not sure if this is correct channel. Sorry if not. I have one Android Kotlin library using

Ktor

and another Java Android project(library + UI application) using mentioned Kotlin library and its api. Unfortunately i can’t compile the UI application using both mentioned libraries with following message from gradle:

However we cannot choose between the following variants of io.github.pdvrieze.xmlutil:serialization:0.84.0:
          - androidRuntimeElements-published
          - jvmRuntimeElements-published
        All of them match the consumer attributes:

Have you ever had similar problem? I can’t find any way how to solve this.

Hello, any example for using ViewModel in the shared layer which has state flow?

Hi guys, I have a question around a Multiplatform SDK. I'm wondering if it's possible to build UI Components in the Android Portion of the SDK only to be consumed within a regular android app? (Jetpack Compose preferred, but open to Jetbrains Compose)

I'm trying to build a Multiplatform library for Android and iOS. I'm very inexperienced with gradle and KMP. Does anyone have links to simple gradle files for this configuration? My app that would consume this uses the standard KMP template in Android Studio (with source sets for androidMain, iosMain, commonMain etc). Particularly useful would be stuff for publishing appropriately to mavenLocal

Hello team, I’m pretty much new in KMM and need some guidance 🙂 Currently I have an Android app where it triggers the

WorkerManager

periodically every 30 minutes in the background to execute some tasks. One of the task is downloading the image from remote server and then store the image file in the local storage. My Questions are 1. How to implement the

WorkerManager

that will be triggered every 30 minutes in KMM ? (of course I hope it runs on Android and IOS) 2. How to store the image file in the local storage ? To make things even more confusing to me, currently in Android we have that thing called

Scoped Storage

. I’m not sure if IOS has this kind of concept as well. How to get around with this problem ?

I am writing an introduction document about KMM，who knows When was KMM proposed？thanks😀

Hello. How can I build my

shared

changes for Xcode? What I do right now run the iosApp to reflect changes in xcode (which I don't like)

Hey all, I'm sure I may be missing something specific to my gradle setup, but has anyone encountered an error of

Could not find :kotlin-native-prebuilt-macos-x86_64:1.7.21.

when trying to compile a shared module for kotlin multiplatform mobile? I know it's part of the 1.7.21 release (because I see it here https://github.com/JetBrains/kotlin/releases) but gradle isn't finding it, maybe my repositories aren't setup right?

Hi i am new in KMM and i ' am starting to use and study so... I have a first question. Can I use Kotlin Flow in KMM I' d like create an app crossplatfom and i want use Kotlin Flow.

Hey everyone, I am currently facing a problem with Gradle syncs in a KMM project. Every time I have to sync, it downloads all the pods again. I have not changed the default config created by the KMM AS plugin.

Hi, Our team is interested in building our Android and iOS apps using KMM. Looking for guidance from an SME in KMM. Can someone please let me know whom I should speak to?

I am using a jvmMain sourceset to share code across Desktop and Android*.* • IDE is recognising it ✅. • Apps Builds Fine ✅. Facing a Runtime Crash : NoClassDefFound ❌ . Any help is appreciated.

Did you ever wonder, how to call Rust code from Kotlin Multiplatform? I've build Kotlin Multiplatform bindings for uniffi if you are interested. Currently only JVM and Native are supported as targets, but I'm working on JS support too.

I have the following data class in my common code:

data class SomeModel(val createdAt: Instant)

In JS and Darwin targets, do you any recommandation to provide native dates for the

createdAt

property? Details in thread ➡️ 🧵

I’m getting

Entry rest/lib/model-jvm.jar is a duplicate but no duplicate handling strategy has been set. Please refer to <https://docs.gradle.org/7.5.1/dsl/org.gradle.api.tasks.Copy.html#org.gradle.api.tasks.Copy:duplicatesStrategy> for details.

It’s because I have two Gradle modules that are called

model

, see a related thread for Kotlin/JS. Now there’s the clash also for JVM modules, but I cannot see an equivalent of

moduleName

for

kotlin { jvm { … } }

. Please advise!

just stumbled upon it as well, asking again: https://kotlinlang.slack.com/archives/C3PQML5NU/p1669626349157219

Hi everyone, sorry if the question has already been answered but I can't seem to get Room working as an Android dependency in my kmm library. I've added the below implementation :

val androidMain by getting {
    dependencies {
                implementation("androidx.room:room-runtime:$roomVersion")
                implementation("androidx.room:room-ktx:$roomVersion")
                implementation("androidx.room:room-common:$roomVersion")
//                kapt("androidx.room:room-compiler:$roomVersion")
...

And also under the plugins block

plugins {
  id("kotlin-kapt")
}

But I'm getting the error : "cannot find implementation for XDatabase" when the app is running. I have no issues compiling. I don't really understand what is missing or misconfigured. Any help would be great thanks 🙂 PS : I'm migrating an android library to kmm and haven't moved every dependency to kmm ones like SQLDelight...

Hi, I am new to KMM. Looking for in-depth tutorials on the beta version.

I am trying to use an external shared library for some platform of a multiplatform project. This works perfectly but IntelliJ is just not able to resolve the generated code. More details inside the thread.

What is a good Crash reporting system to use for a KMM application?

Is there no

until

function for

Float

in common code?

Hi guys, I have a question on the sample SpaceXNews App that KMM doc provides. The tutorial link is here Create a multiplatform app using Ktor and SQLDelight, source code is on github, I got a crash on iOS App when I try to test on SwiftUI. The crash happens on

RocketLaunchRow_Previews

when I try to make a

mockRocketLaunch

. It seems the

mockRocketLaunch

can not be initialised. From the crash log, I think it might be native memory model issue, however, I could not get useful information to find out the root cause. Could anyone provide more information on the crash? Thanks.

Hey everyone. I've gotten my Kotlin Multiplatform running on an iOS app. However, a couple seconds after running the app, it crashes, giving the error

Function doesn't have or inherit @Throws annotation and thus exceptions isn't propagated from Kotlin to Objective-C/Swift as NSError.

If I understand correctly, because Kotlin has no concept of checked exceptions, where Swift only has checked errors. Though I do not understand how I fix this, the documentation doesn't make that too clear for me. Does anyone know how to fix this?

Hello, how do I make a

fatJar

with kotlin multiplatform ?

Do we have anyone here successfully using Ktor 2.x on iOS 12? Looking at KTOR-4159, it appears to be fixed, but I don't think it is. Last activity was in early September suggesting to use

io.ktor:ktor-client-darwin-legacy

instead of

io.ktor:ktor-client-ios

, but after making that change I can't even build the app:

** ARCHIVE FAILED **
The following build commands failed:
PhaseScriptExecution [CP-User]\ Build\ shared ~/Library/Developer/Xcode/DerivedData/iosApp-dwshccrfrznbhwgdphnxyuqdispt/Build/Intermediates.noindex/ArchiveIntermediates/My\ App/IntermediateBuildFilesPath/Pods.build/Staging-iphoneos/shared.build/Script-80ED0967EE0BBCFEB52FF26F11A47A90.sh (in target 'shared' from project 'Pods')

I'm using Kotlin 1.7.21 and Ktor 2.1.3. I've tried downgrading all the way to Kotlin 1.6.0 and Ktor 2.1.1 (the version in which it was supposedly fixed), but no luck. Thanks in advance!

When applying Kotlinx-Serialization and KMP-NativeCoroutines plugins in the same KMP module, getting this error during configuration:

> Cannot add task 'commonizeNativeDistribution' as a task with that name already exists.

Any ideas?

Hello, I decompiled a java class inside my kmp jar. But I see some weird things

public final Object connectLocal(@NotNull final Credential.LocalMode credential, @NotNull final List features, @NotNull final Function1 configuration, @NotNull Continuation $completion) {
      return FlowKt.callbackFlow((Function2)(new Function2((Continuation)null) {
    ...
};

The last argument isn’t used, but in

callbackFlow

we pass null instead of the completion. Any idea ?

Where should I keep the viewModel? In common code or platform spesific?
