Hey everyone, is there any way to specify the values for common fields of an enum class in commonMain? This is what I know works: commonMain:

expect enum class ImageTargetType {
    USER,
    DEVICE;

    val code: String
}

androidMain:

actual enum class ImageTargetType(
    actual val code: String,
    @DrawableRes val defaultImageResId: Int?,
) {
    USER("User", R.drawable.ic_default_user),
    DEVICE("Device", null),
}

This is what I wanted: commonMain:

expect enum class ImageTargetType(val code: String) {
    USER("User"),
    DEVICE("Device);
}

androidMain:

actual enum class ImageTargetType(
    @DrawableRes val defaultImageResId: Int?,
) {
    USER(R.drawable.ic_default_user),
    DEVICE(null),
}

I need to build an emoji, I was using

Char.toChars(0x1F1E6 - 0x41 + ‘A’.code).concatToString()

to get 🇦 emoji (and then build a country flag of two such letters). But now

toChars

marked deprecated. I checked out https://blog.jetbrains.com/kotlin/2021/04/kotlin-1-5-0-rc-released, and I can’t seem to find the replacement. What am I missing?

Hello, I’m having this error:

Cannot inline bytecode built with JVM target 1.8 into bytecode that is being built with JVM target 1.6. Please specify proper '-jvm-target' option
Adding support for Java 8 language features could solve this issue.

And if I choose “fix it” the IDE adds this to my

build.gradle.kts

in shared module:

android {
   ...
    compileOptions {
        sourceCompatibility = JavaVersion.VERSION_1_8
        targetCompatibility = JavaVersion.VERSION_1_8
    }
    kotlinOptions {
        jvmTarget = "1.8"
    }
}

Thing is,

kotlinOptions

throws unresolved reference. How can I fix this? Thanks 🙏 ps: don’t know if it’s related or just a coincidence, but I got this error after adding multiplatformSettings lib 🤔

When I publish my KMM library to Maven and try to add my dependency to an Android application it seems I have to declare it like this for it to work

releaseImplementation 'io.github.tyczj:myLib-android:0.X.X@aar'
debugImplementation 'io.github.tyczj:myLib-android-debug:0.X.X@aar'

What do I have to do to be able to add the dependency like one would for basically every other KMM or Android library? like this is what I am looking for

implementation 'io.github.tyczj:myLib-android:0.X.X

Hi everyone! We’re running a survey to better understand how Kotlin beginners get started with the language. It will help us improve our learning materials and identify where users expect to find them. If you remember how you were first introduced to Kotlin, or you’re currently picking it up, you could really help us out by completing the survey: https://surveys.jetbrains.com/s3/t-kotlin-users-survey Thank you! 🙂

I am attempting to use Okio for File/IO and Square claims it's MPP, but I only see JVM implementations. Has anybody gotten this to work for a JVM/JS MPP? Thanks

Attempted to create a new KMM project. Have the latest Intellij & Canary Android Studio. Both apps created empty projects when creating a test project. Only the stable version of AS worked

sourceSets {
        named("commonMain") {
            dependencies {
                implementation(project(":common:utils"))
                implementation(project(":common:database"))
                implementation(project(":common:main"))
                implementation(project(":common:edit"))
                implementation(Deps.ArkIvanov.MVIKotlin.mvikotlin)
                implementation(Deps.ArkIvanov.Decompose.decompose)
                implementation(Deps.Badoo.Reaktive.reaktive)
            }
        }
    }

    sourceSets {
        named("iosMain") {
            dependencies {
                api(project(":common:database"))
                api(project(":common:main"))
                api(project(":common:edit"))
            }
        }

From the Compose Todo sample app. Can someone explain to me why are we implementing the projects in the commonMain and then api them in the iosMain? Doesnt iosMain inherit from the commonMain? What do we achieve/ what's happening here?

Hi, how are you share “XcFramework’ to Xcode project ?

Is there support to have both Android and Jvm targets at the moment? I was wonder while writing this 😅

Is it possible to override

src/target/kotlin

? My idea is moving to

project/common/Platform.kt
project/commonTest/PlatformTest.kt
project/ios/Platform.kt
project/iosTest/AnotherTest.kt
project/jvm/Platform.kt
project/jvmTest/AnotherTest.kt
...
project/build.gradle.kts

Hi, one questions regarding classes which contains

companion object

. Are that classes fully garbage collected on android as well as on ios?

[KMM/iOS/Cocoapods] Has anyone had any luck with usage of cocoapods in iOS part of KMM library? I think I check most of the possible threads on SO/youtrack/samples etc, but can't get Amplify library to work Inside the iOS (tried iosx64 etc also as suggested in some ticket about that) module I can import the cocoapods.Amplify.* but all I see is 3 Double values from it and no classes that should be present in the Amplify library (checked it first on a native ios project using same pods) If any of You uses the cocoapods inside KMM, how do You do it? Could anyone help me with getting it to at least call Amplify.configure() from within the ios module of shared library? Including a simple project that represents my problem in iosMain/Platform.kt: https://github.com/Bezkarpie/KMMcocopods Thanks! : )

Anyone know hot to solve: Showing All Messages

No enum constant org.jetbrains.kotlin.gradle.plugin.mpp.NativeBuildType.ALPHA

If I only need to build the web component of a multiplatform module is there a way I can disable the build of the other platforms (android/ios) to save build resources? e.g. in a CI environment

Wow. Trying out KMM Plugin in Intellij. I didn’t realize it would be so bad

Hi, is there a simple way to run just a subset of my unit tests? (targets are jvm, ios and tvos)

Hi everyone! I don't know if it has to do with KMM, but I can't build a multiplatfom project anymore, which was fine a month ago. I am using dataBinding in the android app and now getting Unresolved reference: generated and Unresolved reference: BR after

Does anyone know what's missing? There is also

> Task :androidApp:kaptDebugKotlin
[WARN] Can't find annotation processor class android.databinding.annotationprocessor.ProcessDataBinding: javax/xml/bind/JAXBException

Also it builds and runs if I just Rebuild in AS. If I do ./gradlew clean build, then it fails Android build.gradle

Is there an annotation to tell the compiler that expected field declaration should be a property on JVM?

expect class File(path:String) {
  val path: String // <-- Needs to be property on jvm
}

// jvmMain
actual typealias File = java.io.File // <-- hooks in to `private String path` field instead of `public String getPath()` getter

I’ve been trying to implement D-KMP in my project but it’s too difficult for a junior as a result I have no clue how to implement it in my project. For context I’m not an android or ios developer, I know react and have worked with react native for mobile development. I really want to make multiplatform app with a shared state between ios and android but I have no clue how to implement it or which guide I could use. What would you all suggest?

Has any one ever had problems with nested classes in iOS? I am getting an

UnsupportedOperationException

when running CocoaPods when my KMM project uses a nested class. Any ideas? Kotlin 1.4.30

Adding

implementation("org.jetbrains.kotlinx:kotlinx-coroutines-test:1.5.0-native-mt")

to my

commonTest

source set messes up the IDE integration of my project, For example I see the annoying “Cannot find declaration to go to” popup when I Cmd-Click a type to see the declaration, code completion doesn’t work, and so on. Has anyone else experienced this and if so are you aware of a fix or workaround?

Hi All, I’m exploring KMM as per https://kotlinlang.org/docs/mobile/integrate-in-existing-app.html#create-a-shared-module-for-cross-platform-code When I reach this step

./gradlew packForXcode

it complains…

* What went wrong:
Task 'packForXcode' not found in root project 'Simple Login'.

Hey Everyone, I am new to KMM and run into the same problem over and over again. When I create a project with the KMM plugin and open the xcworkspace file everything works fine. But sometimes after relaunching Xcode it fails to build all of a sudden and I get the error message:

no such module 'shared'

I tried rebuilding the project but nothing helps. When I create a new project it works fine at first. I also tried to run

pod update

but nothing helps. P.S I'm pretty new to KMM and IOS EDIT I fixed it by removing

implementation("io.ktor:ktor-client-ios:1.5.4")
implementation("org.jetbrains.kotlinx:kotlinx-coroutines-ios:1.5.0-native-mt")

from the iosMain module. What is the right dependency for using coroutines or something for concurrency?

Does anyone know what this new Gradle plugin named

org.jetbrains.kotlin.multiplatform.pm20

is? It was just created for version 1.5.20-M1 (no prior release):https://plugins.gradle.org/plugin/org.jetbrains.kotlin.multiplatform.pm20

is there a way use jetpack compose in

androidMain

in kotlin multiplatform module?

Hello everyone I started receiving this error message while trying to compile the iOS app:

> Task :shared:linkDebugFrameworkIos
e: Compilation failed: Deserializer for declaration public kotlinx.coroutines/cancel|-8901161077954086727[0] is not found

Someone here has any idea how can I resolve this coroutines reference?

Noob question, when running kmm, where the targets are android and ios, is the output of shared library on android jvm bytecode, or do both platforms get native code?

Hi everyone, I would like to learn more about KMM where is the best to start? Is there any books or video training you guys would recommend?
