does anyone know how to resolve this issue? i tried invalidating cache & restart and some suggestions from Google but no luck.

Hey everyone! 👋 I’m starting the dev of a multiplatform app and I wanted to skip the server-side development by using any BaaS. At first, I thought of using Firebase, but I found that there isn’t an oficial pure Kotlin SDK. This one looks good but it doesn’t contain all features. Do any of you know of any BaaS that has a pure Kotlin SDK or has used the open source Firebase SDK? Thanks! 🙇

Is previewing compose still not a thing for multiplatform? I have shared compose code and trying to preview it. It seems that

androidMain

supports preview annotation but I don't get the option to run it. The only option would be to preview directly in the Android App but the app doesn't and shouldn't depend on some stuff that is required for previewing (for stubbing the data).

I’m looking into the multiplatform and see it’s in

alpha

. Is there any timeline for

beta

and

stable

?

Also I see “managing coroutines”. I’m not sure what that means. I know what coroutines are, but I don’t understand the meaning of managing them in multiplatform. So my main platforms would be Java/Kotlin and JavaScript. Will this convert any coroutines to async/await in JavaScript?

I have an issue when I try to provide Ktor’s

HttpClient

instance using Koin. Here’s my code:

single {
        val buildVariant: BuildVariant = get()
        val httpClientEngine: HttpClientEngine = get()
        val kotlinxSerializer: KotlinxSerializer = get()
        val tokenRefresher: TokenRefresher = get()

        HttpClient(httpClientEngine) {
            install(JsonFeature) {
                serializer = kotlinxSerializer
            }

            install(Logging) {
                ...
            }

            install(HttpSend) {
                intercept { clientCall, requestBuilder ->
                    ...

                    requestBuilder.takeFrom(clientCall.request)

                    val newAccessToken = tokenRefresher.refreshToken()
                    requestBuilder.setAuthorizationHeader(newAccessToken)
                    execute(requestBuilder)
                }
            }
        }
    }

The problem is in this line:

val newAccessToken = tokenRefresher.refreshToken()

I get

kotlin.native.concurrent.InvalidMutabilityException: mutation attempt of frozen org.koin.core.scope.Scope

Can someone please explain why do I get this exception if I’m not trying to modify

tokenRefresher

?

refreshToken

is a suspending function, but for the debugging purposes, I made it a regular function which returns some string constant. The behavior is the same, I still get the same exception. I’m using Ktor version

1.5.2

Trying to build shared KMM lib with EAP version of Ktor, getting this error:

w: skipping /Users/home/.gradle/caches/modules-2/files-2.1/io.ktor/ktor-client-serialization-iosarm64/main-170/8edb8cd38df5e56e4d9bda9941b0588fb1b36305/ktor-client-serialization.klib. Incompatible abi version. The current default is '1.4.2', found '1.5.0'. The library produced by 1.5.20 compiler

I am unsure exactly what the message is saying, and where it might be getting the 1.4.2 version from. All versions are set to 1.5.20.

I have a mpp project with windows target. I am getting "Kotlin not configured" warning in IDEA when I am coding in common source set. How can I fix this? Do I just ignore this?

Is there any mpp library for file io (create files, directories, etc)? https://github.com/Kotlin/kotlinx-io seems to be not in active development. Any alternatives?

Is there any difference between a Kotlin/JVM library, and a MPP library with only JVM enabled? - beside build.gradle.kts and source folder

Has anyone setup their environment to use different Kotlin version when building for Android and building for iOS?

Hi, a bit of a high level question. My company has various products and we are looking to create a shared library to reuse across android/iOS. I could build one huge shared library that supports all of them but that seems wrong, or I could build 3 libraries but that seems a duplication of effort as all of them need some things (date formatting across the company has been standardised) 2 of them are very similar and have a large overlap. How best to approach this? I’m currently thinking a standard lib with global stuff and then ProductA/B lib with a dependency on the standard lib and Project C lib with a dependency on the standard lib

I am trying to figure out how NSURLSessions work with Kotlinx Corountines. I managed got it to work with semaphore.

I’m curious if anyone has investigated Brightscript interop. It seems like the concurrency model could make things tricky, but maybe it wouldn’t be insurmountable.

Hello! Is it possible to depend on jvm target. I have jvm code (with jvm external dependenies) and want to depend on it from jvm and android targets. And it is not good for me to make several gradle modules to achieve it.

Hey Kotliners! Does anybody know when

native.cocoapods

Gradle plugin will support

universal-framework

(fat binary) to distribute KMM library for independent iOS project? We want to use Cocoapods to wrap KMM iOS binaries and use it independently in iOS projects. As I understand at the moment it is impossible to distribute KMM project (only sources) with Cocoapds and connect it to some iOS project so Gradle and other KMM libraries can be delivered

transparently

and build the KMM sources during assembling iOS project. We don't want to make iOS engineers unhappy ;-)

Hi all - Not long ago i did a presentation in my company to introduce them to :kotlinnew: Multiplatform. I have a recorded version , let me know what you guys think 🙂

Has anyone tried out Apollo's multi platform client? curious about anyone's experiences. We currently have an existing GQL backend implementation that is fragmented across 4 apps (2 iOS, 2 Android) and ideally would like to consolidate implementations: https://www.apollographql.com/docs/android/essentials/get-started-multiplatform/

Hi there, does anyone have experience using mavenLocal() with kmm? I made a kmm library named

multiplatform

, and performed publishToMavenLocal. The jar files look to be in my local path .m2 path. So I'm not too sure why I'm getting this error when importing:

- file:/C:/Users/bchadwi/.m2/repository/me/bchadwi/multiplatform-android/1.0.2/multiplatform-android-1.0.2.pom
     Required by:
         project :app > me.bchadwi:multiplatform:1.0.2

Specifically, why gradle is looking for a

multiplatform-android

?

I'm trying to publish my project to maven central, and I'm still stuck with the gpg issue. I can't sign my artifacts for some reason. Is there a simple way to do the signing?

How to correct run code on single thread in kmm? looks like

runBlocking

doesn’t work good with ios. I get tests

passed

on jvm, but on ios it fails and seems that code inside

runBlocking

never executes

Hi everyone! Is there anyone who is developing "thin clients" with KMM (by that we mean apps with mainly web-first business logic like networking, caching, media (e.g. videos) and state & navigation management) and is* *ready to share his experience with us? We would love to learn what difficulties you face during your work to make your life with KMM a bit easier! If you are ready to give a little interview - just hit a :kotlinnew: reaction and I'll gladly DM you

Hey is there any convenient way to load fixtures/resources in common tests without turning those resources into strings? For example JSON files become very ugly to deal with. Any pointers?

I am having problems when I add

kotlin.native.enableDependencyPropagation=false

Good morning everyone, I’m facing issues while using modularization with kmm and iOS app, is there any one with some use case that I can check? I can’t make iOS see the another module inside the shared one Thanks in advance!

I'm trying to create a desktop-compose module for my kotlin multiplatform project but the compose module doesn't seem to see the shared project. I've included it in the gradle file but for some reason it can't see the files. Is there something that is preventing it?

hello, does anyone know what would be the right target for “armv7k” architecture when building for WatchOS on KMP? I’ve looked at the available targets https://kotlinlang.org/docs/mpp-dsl-reference.html#targets but don’t see “armv7" or not clear if it’s part of one of the “watchos*” ones
