Are there any

cbor

implementations other then the

kotlin.serialization

? I am looking for something implementing RFC 8949 https://www.rfc-editor.org/rfc/rfc8949.html Native android and ios solutions would also work for me.

Hello everyone. So, I was having an issue with dependency resolution not working. Which is related to this: https://youtrack.jetbrains.com/issue/KTIJ-22111 The current solution was staying on Bumblebee or Intellij IDEA 2021.3 with AGP 7.04. This has worked perfectly for quite a while but now even Intellij IDEA 2021.3.1 and AS Bumblebee do not work. I'm using Windows 11. I have 2 Multiplatform projects and no dependencies in commonMain or androidMain are being resolved with Intellij IDEA 2021.3.1 (only those is jvmMain and jsMain work). In Bumblebee they all get resolved but break when you build and run the project (they start working again after you manually resync gradle). In Intellij IDEA 2022.2 EAP7, AS Chipmunk and Dolphin (which are know to have this issue), import for things originating from commonMain do not work inside commonMain or androidMain for all imported multiplatform libs (either from another module within the project or downloaded) Now, the issue from Intellij IDEA 2022.2, AS Chipmunk and Dolphin are known and fixes are underway. What I was wondering is why did it also break (in a different way) for Intellij 2021.3.1 and Bumblebee which were working perfectly fine with the old AGP versions. After looking

idea.log

this section seems to repeat itself for both Intellij IDEA 2021.3.1 and AS Bumblebee which shows some errors when syncing: https://pastebin.com/Q8qYJpgc. Is this related to the issue or is there something wrong with my config. One of those projects can be found here: https://github.com/Thinkrchive/Thinkrchive-Multiplatform. The branch

working-kotlin-js-support

is the one I'm currently working on and the one with all the issues. The 2nd project (larger one) is not open source unfortunately but has a very similar project structure and gradle configuration, but they both exhibit the same issues.

Has anyone ever run into an issue when building an iOS project with a framework built from a multiplatform that fails with something like

mylibrary.framework/Headers/mylibrary.h:488:16: imported declaration 'MylibraryKotlinStringCompanion' could not be mapped to 'KotlinString.Companion'

hello, it might be trivial but... how to format a double to two decimal points like 1.123456 -> "1.12" so the decimal point is marked with

.

with pure kotlin? I can see that

.format

in kotlin stdlib uses java

java.lang.String.format

so it depends on the current locale whether it is

.

or

,

I want to be able to enforce it to use

.

.

does anyone know what this message means? I can't tell how to deal with it. I'm hitting this in AppCode but I'm not sure if it's specific to that IDE

Module 'android' uses an old-style KMM project configuration and cannot be updated automatically. Consider replacing the Kotlin Android plugin with Kotlin Multiplatform manually.

I created an androidCommonTest source set to share code between androidTest unit and androidAndroidTest instrumented tests. The change works as expected if I run the tests in the terminal, but it breaks the gradle sync in Android Studio, which fails with the error:

Key androidCommonTest is missing in the map.

There's no stack trace or further error info, unfortunately. In fact, the top-level build log completes with

BUILD SUCCESSFUL

. So it's unclear how to troubleshoot this. This is the build.gradle.kts change I made:

kotlin {
  ...
  sourceSets {
    ...
    val commonTest by getting {
      ...
    }
    val androidCommonTest by creating {
      dependsOn(commonTest)
    }
    val androidTest by getting {
      dependsOn(androidCommonTest)
      ...
    }
    val androidAndroidTest by getting {
      dependsOn(androidCommonTest)
      ...
    }
  }
}

Hello guys What do you use for dependency injection for Multiplatform mobile?

Is MVVM the best option as design pattern in KMM? Is there any other best/commonly used or native way?

How do you test async callbacks in commonTest (to run on Android and iOS)? Android tests run on TestRunner's pseudo main thread, allowing callbacks to call the real main thread in parallel. But iOS runs tests on the actual main thread, causing callbacks to deadlock while test code waits on the same thread. Is there a way to either change this behavior of which thread iOS tests are run on, or write tests in a way that works on both platforms?

How to create a new KMM project with iosApp in Storybord + UIKit Currently the default iosApp created with template is one with SwiftUI. And I am not seeing any option to switch SwiftUI to UIKit Storyboard while creating a KMM project using Android Studio

Is it planned to allow modifying the constantly JS library versions with vulnerabilities (🙃) in a better way than in the Gradle DSL? Maybe on the same yarn or in another different yarn file? Or on a file which can be compatible with Renovate/Dependabot. This one should be great because the web world is awful in terms of vulnerabilities and updating the JS libraries manually is… 😕

Look into usong TOML catalogues for your versions. I'm sure dependabot will be processing the catalogues soon

Hi folks! I’m Anastasiia, Product Manager for Kotlin Multiplatform, and I’m looking for Multiplatform newcomers to participate in a study! TL;DR: If you’re interested in Kotlin Multiplatform Mobile but have not had a chance to try it yet, you can get started by participating in the onboarding research our team is conducting – and get a reward K We really want to know how developers interact with Kotlin Multiplatform Mobile from their first moments with it to the completion of their first cross-platform applications. If you have Kotlin and/or Android experience, have wanted to try Kotlin Multiplatform Mobile for a long time but haven’t had the chance, and are ready to get started with it under our supervision while sharing your feedback, then you’re just the hero we’re looking for! Your goal will be to write a simple KMM app, describe your experience in a diary, and have a couple of calls with us to discuss it all in person. Our goal is to tune our onboarding according to your feedback 🙂 The process will take about 3–4 hours a week for 3 weeks, and at the end, a reward and our infinite gratitude will be yours. If you’re interested, send me a DM. We’ll chat and set up an introductory call where I can tell you more about the study.

I'm using a 3rd party library ("kbox2d") that I published to maven local. Trying to build my project that has kbox2d as a dependency, I get

> Task :compileCommonMainKotlinMetadata FAILED
e: java.lang.IllegalStateException: e: Could not find "C:\Users\Jonathan Ellis\Documents\essaie1-js\build\kotlinSourceSetMetadata\commonMain\com.soywiz.korlibs.kbox2d-kbox2d\com.soywiz.korlibs.kbox2d-kbox2d-commonMain.klib" in [C:\Users\Jonathan Ellis\AppData\Local\kotlin\daemon]

This looks very much like https://youtrack.jetbrains.com/issue/KTIJ-18321, except I get this with gradle commandline as well as in intellij. I verified that the file it's looking for is in fact in the first directory mentioned. Is there a workaround to stop it from looking in AppData\Local\kotlin\daemon ? ETA: I can use the library fine for the JVM-only components, it's when I add it to commonMain that it causes problems.

I'm trying to understand C interop for some iOS native code I'm writing. Is it possible to convert ${type}Var to ${type}? I have a CValuesRef<${type}Var> and I need to access the $Type. So I need to grab the ${type}Var from within the CValuesRef and then convert that to ${type}.

Hi all, I am getting

Expected class 'Platform' has no actual declaration in module [my module] for JVM

in the sample app, I assume this is an IDE issue since gradle commands are working fine. I just want to know which Android Studio version I should use for the following settings: Kotin: 1.7.10 AGP: 7.2.1 Gradle distribution: 7.3.3 Gradle JDK: 11 Android Studio: Dolphin | 2021.3.1 Beta 5 (#AI-213.7172.25.2113.8774922)

Is it possible to cast a NativePtr to CValuesRef<*>? I have an existing object that I can call objcPtr() on to get a NativePtr, but I'm not sure how to cast it.

For a KMP project that just targets android and jvm, is it possible to get Android Studio/IntelliJ to not mark Java-specific stuff as an error?

Hello everybody, talking about KMM libraries and iOS. What’s in your opinion the feasibility and likelihood that apple will start detecting apps using KMM and rejecting them in the future?

I updated my KMP project to use koktlin 1.7.10 and everything compiles and works fine. When I however use it as a dependency in another project I get a compiler error: "java.lang.NoSuchMethodError: 'void org.jetbrains.kotlin.cli.common.arguments.K2MetadataCompilerArguments.setUseK2(boolean)". The depending project uses the same kotlin version etc. Anyone encountered anything similar?

I have a strange problem with importing a mpp project in IntelliJ (2022.1.3 Ultimate). More info in thread.

Not sure if right channel, but related to MP and the IDE. I really like when I got a file called Foo open from two different source-sets in the tab it is shown as “jvmMain/…/Foo.kt” and “commonMain/…/Foo.kt”. When I close one of the two source-sets it shows just “Foo.kt”. I personally would prefer that it’d show the sourcesSet/…/ prefix at all times, even if I only got one of them open, instead of me having to look at the breadcrumbs or somewhere else to figure out where I am. If this is not something that is currently available, I will make a feature request, but asking here first to see if someone else has thought of it or if this setting exists already and I haven’t found it.

"Kotlin not configured" ...I've applied the

multiplatform

plugin and even depended on the

stdlib

in

commonMain

- what else is there to convince the IDE it's configured?

I am creating a lib which just helps to ignore tests based on the platform. Problem is expect/actual are failing when I enable JS, as you can see, multiple source sets are being created in the

build/externals/*

and added, so I am getting multiple redeclarations, any way to fix it?

Why do enums turn into

KotlinEnum

in swift? Why not a native enum?

Are there any examples of how to use GCD from iOS via Kotlin? I'm trying to work out a few issues and that would be helpful.
