Hi everyone, I cloned this project to learn Kotlin and React together https://github.com/karakum-team/kotlin-mui-showcase. However , there is nothing displaying on the web page. How can I run this project?

Not sure what channel is best for this, but now that Compose treats kotlinx-immutable types as stable, has the status of the library on the roadmap changed at all? It works fine, but there could be a lot of API improvements (lots of good issues with suggestions on the repo).

on KMM, is there is a way to update the project with latest templates without creating new one?

I am trying https://github.com/voize-gmbh/reakt-native-toolkit to use react-native in the shared module but I am stuck with the setup. Gradle doesn't find react-native. Do you have any hints? Experience?

Hi, I have a multi-module application where

:core

behaves like an umbrella, And I would like to create a separate module just with analytics. But While I run gradle task

assembleXCFramework

I’m receiving this error:

output:
Undefined symbols for architecture arm64:
 "_OBJC_CLASS_$_FIRCrashlytics", referenced from:
   objc-class-ref in result.o
ld: symbol(s) not found for architecture arm64

Also extra information is printed into the console with this information:

Any Idea what is wrong with this configuration ?

Hi! What is the good Multiplatform logging framework available in KMM?

Hi is there a good multiplatform client library for TCP and UDP sockets?

Hi, I working on a KMP application. I want to share the ViewModels for all the platforms (android, ios, desktop). I'm having problems editing a simple TextField on compose. My viewmodels store the inputed text on a MutableStateFlow, that is combined with other flows to produce the model to be displayed, transforming it to a StateFlow with stateIn in the viewModel, and then transforming it to a compose state with collectAsState. The problem is that I have a race condition, and when the user inputs the text the cursor makes strange behaviours. Does anyone have a solution, or an example with shared viewmodels with a textFiled (the samples I've seen do not contains texts fields, just data displaying).

Not sure where to ask this: what's the biggest possible

String

literal in Kotlin? Given multiplatform resources are not really a thing, how bad of an idea is it to store large texts/images in

String

literals?

What’s the trick to only create and link XCFramework using only target architecture when building locally? I want to speed up the XCFramework creation by only building the local architecture.

I'm trying to reproduce a bug with

*compileKotlinMetadata*

. In my task list, I have this:

compileCommonMainKotlinMetadata - Compiles the kotlin sources in compilation 'commonMain' (target metadata (common)) to Metadata.
compileKotlinMetadata - Compiles the kotlin sources in compilation 'main' (target metadata (common)) to Metadata.

What's the difference between these two? I don't have any 'main' sourceSet that I know about

I get a strange error in iOS with Kotlin 1.8.0.

> Task :shared:linkPodDebugFrameworkIosX64 FAILED
e: There are still 2 unbound symbols after generation of IR module <shared>:

More details can be found here: https://github.com/adrielcafe/bonsai/issues/11 Does anybody have an idea how to fix that or is this indeed a compiler/linker error?

Hey, I have a KMP library (ios + jvm) (kotlin 1.7.20) that depends on another KMP library (also ios + jvm) that just upgraded to 1.6.21 from 1.6.10 and I started seeing this error when try to build with the updated library:

Could not determine the dependencies of task ':my-module:compileKotlinMetadata'.
> Could not resolve all task dependencies for configuration ':my-module:metadataCompileClasspath'.
   > Could not resolve com.squareup.workflow1:workflow-runtime:1.8.0-beta11.
     Required by:

However we cannot choose between the following variants of com.squareup.workflow1:workflow-runtime:1.8.0-beta11:

          - jvmApiElements-published
          - jvmRuntimeElements-published
< and so on and so forth >

I've seen this before when the library happened to be shipping a ktlint artifact as well but not sure what could be causing this apart from the kotlin version change.

Hello, I'm trying to use '*cinterop*' tool (from this tutorial: https://kotlinlang.org/docs/native-c-interop.html#simple-example) to see how static C bindings would look like. I made a single C function, and def file and I call from within cinterop folder:

[ridicolous relative path].konan/kotlin-native-prebuilt-macos-aarch64-1.7.20/bin/cinterop -def App.def

and I get:

Exception in thread "main" java.lang.Error: /var/folders/80/ncv5m6mj2yq0zg6nnn0cl46c0000gn/T/8421264523268807030.c:1:10: fatal error: 'App.h' file not found

I called it from the folder where 'App.h' is located, and I have no idea about this path in error message. Does cinterop supposed to work on macOS right now? How can I make my chances of success better :x

Hi, is there any way how to exclude some folders from publish? Long story: With team we build multiplatform kotlin project (NPM, Maven) for multiregional web application. We have some regional implementation which use common shared functionality, but full build has 42MB of JS code. This is why we need publish only selected region with common functionality and exclude other regions.

Does anyone happen to know how would I publish a KMM Library to an internal Github repo and use that as pods in my existing iOS project via Podfile.

When adding a dependency to

commonMain

that does not support a specific platform such as Kotlin/JS, how can I exclude the dependency from

jsMain

?

If I build my project through the ui with

Gradle -> build -> build

I get the following error :

Execution failed for task ‘myModuleallTests’.

> Failed to execute all tests:

myModulejsBrowserTest: java.lang.IllegalStateException: command ‘/Users/jeantuffier/.gradle/nodejs/node-v16.13.0-darwin-arm64/bin/node’ exited with errors (exit code: 1)

If I use the command line

./gradlew build

it works without any error (if I hit command + enter, Intellij uses the same gradle dæmon than the UI, or whatever it does compared to just hitting enter, and crashes with the same error)

👀 Is there a way to exclude certain architectures from being compiled and linked when building XC Framework locally? (want to do this to speed up dev build times)

Hey everyone.. is there a way to integrate a SwiftUI multiplatform project (i.e. it supports iOS, macOS, tvOS, and watchOS) in a KMP project? If so, is there an example repo for the same?

is it possible to import an annotation depending on the platform? for example

androidx.compose.ui.tooling.preview.Preview

for

Android

androidx.compose.desktop.ui.tooling.preview.Preview

for

Desktop

CommonMain

use

@Preview

which resolves to the above at compilation/analysis

Hey, could anyone point me to android+ios KMM monorepos on Github preferably with some kind of CI workflows for pull requests and releases? Trying to merge our 3 repos and would like to refer to how people have things setup.

Hi, guys. I recently upgraded to kotlin 1.8.0 and found that the new

androidInstrumentedTest

doesn’t dependsOn

commonTest

by default, is this a bug or desgin this?

Hi guys, I build this geometry playground project using compose multi platform and 99% of the code is shared between android and desktop. I'm planning to add web in the future https://github.com/M0Coding/Compose-Geometry-Playground

when using the umbrella module approach for adding kmm as a dependency to an iOS app, can a non-umbrella module contain pod dependencies? I get this error for all iOS targets.

Undefined symbols for architecture [iOSTarget]:

Will Apple let KMM succeed? Effectively, Multiplatform Compose and KMM will make iOS Developers, XCode or Swift obsolete. So, what is in it for them? And what guarantees the Kotlin Multiplatform approach will be possible to be used for development in 2-3 years?

if I want to leverage `expect`/`actual` mechanism and I want to have abstraction for testing, would this be good practice or there is some other way?

interface AccountStore {
    val account: Flow<Account>
}

class AccountStoreImpl(platformAccountStore: PlatformAccountStore) : AccountStore {
    override val account = platformAccountStore.account
}

expect class PlatformAccountStore {
    val account: Flow<Account>
}

AccountStore

is abstraction and it’s used for testing and

PlatformAccountStore

is, as name says, where I will implement Android and iOS specific behaviours

Hello guys, I need your help I'm building kmm application and part of the api call is md5 hash key, I made the implementation for android part but for iOS I couldn't use CryptoKit because it's pure swift and using the CoreCrypto I faced a lot of trouble converting the swift code to kotlin this is the contract:

expect object EncryptionHelper {
    fun md5(input: String): String
}

this is the Android part:

import java.math.BigInteger
import java.security.MessageDigest

actual object EncryptionHelper {
    actual fun md5(input: String): String {
        val md = MessageDigest.getInstance("MD5")
        return BigInteger(1, md.digest(input.toByteArray())).toString(16).padStart(32, '0')
    }
}

Hello Guys, KMM shared XCFramework is around 80 Mb (release) for iosX64(), iosArm64(), iosSimulatorArm64() architecture, Is it possible to reduce it?
