I am trying to build a project with a Kotlin backend to show how this will work. In my shared build.gradle file I have this:

kotlin {
    android()
    iosX64()
    iosArm64()
    iosSimulatorArm64()
    jvm()

Near the end I have this:

val jvmMain by getting {
            dependencies {
                implementation("io.ktor:ktor-client-apache:${Versions.ktor}")
            }
        }

    }
}

android {
    compileSdk = 32
    sourceSets["main"].manifest.srcFile("src/androidMain/AndroidManifest.xml")
    defaultConfig {
        minSdk = 30
        targetSdk = 32
    }
}

tasks.withType<org.jetbrains.kotlin.gradle.tasks.KotlinCompile> {
    kotlinOptions {
        jvmTarget = JavaVersion.VERSION_11.toString()
        freeCompilerArgs = listOf("-Xallow-jvm-ir-dependencies", "-Xskip-prerelease-check",
            "-Xuse-experimental=kotlinx.coroutines.ExperimentalCoroutinesApi", "-Xjvm-default=all"
        )
    }
}

It recognizes jvmMain as I had to include the expected functions. In my server build.gradle I have:

import org.jetbrains.kotlin.gradle.tasks.KotlinCompile
plugins {
    kotlin("jvm")
    id("kotlin-platform-jvm")
    id("war")
    id("application")
    kotlin("plugin.serialization")
    id("kotlinx-serialization")
}


dependencies {
    implementation(project(":shared"))
Snipped rest
}

kotlin {
    sourceSets.all {
        languageSettings {
            optIn("kotlin.RequiresOptIn")
        }
    }
}

java {
    sourceCompatibility = JavaVersion.VERSION_1_8
    targetCompatibility = JavaVersion.VERSION_1_8
}

When I look at anything from the shared project it goes to the androidMain version, not the jvmMain version. How do I get it to find the correct versions of the classes?

Why using kodein is beneficial rather than using koin in KMM project?

Is there a way in KMM to have a json config file in the shared part which we can be later read from both platforms?

Hello! I have a question regarding the development process of KMP and Kotlin lang in general. First of all, I would like to say a big thank you to JetBrains team - the tools that you guys create are top-notch. I enjoy using them - be it an IDE or the Kotlin language. I also see that the development never stops and even if there are flaws/bugs - they get fixed fast, and each update makes the products only better. Currently the team I am working with is deciding on a tech stack for our upcoming mobile app, and the KMP/KMM looks very promising to us. We see that the multiplatform project is in alpha, but it is Ok to us assuming that the project is supported and we will be seeing new releases. There was a 1.6.20 version of Kotlin released just a couple of days ago, which is great! My biggest concern is - how is the development going on right now? From what I can tell many Kotlin lang developers are located in Russia. Did the teams manage to return to the same release-cycle tempo as previously? Or maybe there is a pause in development? Is it possible for some projects to be stopped at all? Anything of it is understandable assuming the circumstances. Also, I would like to add that I am very grateful for the clear position the company has taken regarding the war. I hope that everyone in JetBrains team is safe, wherever they are.

Is it possible to create custom lint checks in a KMM project? I want to make a custom annotation and have the method/s that are annotated with my annotation highlighted in the IDE with a warning when it is used. Everything I have seen about custom lint checks is with normal android apps

How do you encode and decode Base64 in common code? Looks like this contains in ktor, but it is marked as InternalApi

Anyone had problems using kotlin classes on a thread in swift, and having errors like : Uncaught Kotlin exception: kotlin.native.IncorrectDereferenceException: illegal attempt to access non-shared <object>@27c0f38 from other thread And after trying to annotate the class with either SharedImmutable or ThreadLocal getting -> @ThreadLocal is applicable only to property with backing field, to property with delegation or to objects

ok this is something

Uncaught Kotlin exception: kotlin.IllegalStateException: There is no event loop. Use runBlocking { ... } to start one.

ohh maybe i misread

Coroutines 1.7.0 will be released without

native-mt

companion and we are gradually stopping the support of

native-mt

during the course of

1.6.x

lifecycle. We still are ready to accept PRs or release versions with the new Kotlin if there is a need to, but new coroutine features won't get

native-mt

support.

For the life of me I can't get 2 separate MPP modules working inside one project. I have 2 projects: • dom • mvu (which should refer to dom) I get errors ranging from "Projects must be configuring" to modules not loading tat all. Besides that, Gradle is complaining that I don't have configured any JS module, which I have.

Hey folks, what do you thing is a good option for iOS framework distribution when it came to create a KMM library ? • Apple XCFrameworks • CocoaPods • Apple Frameworks

Hello, everyone 👋. I’ve just created a new KMM project, but when tried to open it on XCode it shows the following error:

The operation could''t be completed. Unable to locate a Java Runtime.
Please visit <http://www.java.com> for information on installing Java.

Command PhaseScriptExecution failed with a nonzero exit code

From Android Studio I even can run it on an iOS emulator, but I can’t get preview or run it from xcode. Anyone to help me on that 😄 ?

Hello, everyone 🖖, We’ve just updated KMM project to have the same structure as the plugin created (before we did everything manually and was used as a library with publishing on Maven). We’re using kotlinx coroutines native-mt version with the strictly, iOS run smoothly, Android on build give this error:

org.gradle.internal.resolve.ModuleVersionResolveException: Could not resolve org.jetbrains.kotlinx:kotlinx-coroutines-core:1.5.0-native-mt.

We tried to move the strictly on iOSMain and remove it from commonMain, Android run but iOS Crash for runBlocking{} no event loop. Does someone have an idea how to solve it🙏? Thank you

Hey Everyone ✌️. Can someone guide me what is d/w of this ktor library

"io.ktor:ktor-client-core:2.0.0-beta-1"

In android

"io.ktor:ktor-client-android:2.0.0-beta-1"

In Ios

"io.ktor:ktor-client-ios:2.0.0-beta-1"

Do we need to add core, android and ios library in the commonMain, androidMain and iosMain respectively?

sourceSets {
    val commonMain by getting
    val commonTest by getting {
        dependencies {
            implementation(kotlin("test"))
        }
    }
    val androidMain by getting
    val androidTest by getting
    val iosX64Main by getting
    val iosArm64Main by getting
    val iosSimulatorArm64Main by getting
    val iosMain by creating {
        dependsOn(commonMain)
        iosX64Main.dependsOn(this)
        iosArm64Main.dependsOn(this)
        iosSimulatorArm64Main.dependsOn(this)
    }
    val iosX64Test by getting
    val iosArm64Test by getting
    val iosSimulatorArm64Test by getting
    val iosTest by creating {
        dependsOn(commonTest)
        iosX64Test.dependsOn(this)
        iosArm64Test.dependsOn(this)
        iosSimulatorArm64Test.dependsOn(this)
    }
}

I am getting some strange Gradle issues again:

Caused by: org.gradle.api.GradleException: Cannot find dukat@0.5.8-rc.4 in yarn.lock
        at org.jetbrains.kotlin.gradle.targets.js.yarn.YarnEntryRegistry.find(YarnEntryRegistry.kt:37)

Did you guys ever set up a repository with a precompiled cocoapod library from the kotlin shared code? I know it could be done with Swift package manager, but I can't imagine programming without autocomplete on swift.

Damn this kind of breaks both my legs

I'm not sure if Scripting Host can be embedded for KMM targets other than JVM. Please let me know if any of you got a simple statement like "a == b" to evaluate in KMM projects! ❤️

In my KMP project, after upgrade to Kotlin 1.6.20, I see this error in IntelliJ only (no error when building from gradle). Is this correct behavior?

Hey I am importing darwin in Kmm

build.gradle.kts

. I tried to import code in class but it giving error. Can someone guide me.

I don't have the

jsmain

or

jstest

directories, nor do I have anything configured for JavaScript in my Gradle files. Yet I see the below output when sync'ing the project. Any thoughts?

Hey, everyone What should I “git ignore” in a kmm project? is there a .gitignore template for it?

In my shared subproject I have this enum. I would like to loop over it in Swift to have toggles.

enum class ClothingTypes(val clothingLabel:String) {
    BLAZER("blazer"),
    BLOUSE("blouse"),
    UNDERSHIRT("undershirt");

    companion object {
        fun getNumberOfItems() = values().size
    }
}

This code isn't going to compile but basically how would I loop over ClothTypes and get each item in the enum? I did this on the Android side already. ClothingTypes.allCases.forEach { item in Toggle(isOn: $isPushEnable) { item.text } } This is basically what I want to do in a loop. Toggle(isOn: $isPushEnable) { Text(list.*get*(index: 0)!.clothingLabel) } Toggle(isOn: $isPushEnable) { Text(list.*get*(index: 1)!.clothingLabel) }

Is there currently a workaround for having a jvm and android sourceset in the same kmm module right now? I'm getting the error that the java plugin is incompatible with the Android plugin. It looks like separate source sets aren't possible right now (I want to use expect/actual for several platforms).

Hey guys. I want to find application version code in Kmm. In specific platform i.e. Android

var versionCode = BuildConfig.VERSION_CODE

it will return

1.1

iOS

let appVersion = "iOS " + (Bundle.main.versionNumber ?? "")

it will return

1.1

The above code is for native. What code should I use in KMM?

How do you sync a SwiftUI TextField with your Kotlin ViewModel using MutableStateFlow?

Hey guys, I need your advice or any sample project. I want to call session endpoint, in which I get accessToken. I want to use in accessToken in other endpoints as a authorisation. In android side we encrypt token and store in sharedpreference. Now I want to change in KMM to share with iOS team. So what is the best way in KMM?

In my sample multiplatform app I upgraded ktor to 2.0.0 and now I'm getting a build error:

e: Could not find "io.ktor:ktor-utils-cinterop-utils" in [/home/jw/projects/kotlin-bars, /home/jw/.konan/klib, /home/jw/.konan/kotlin-native-prebuilt-linux-x86_64-1.6.10/klib/common, /home/jw/.konan/kotlin-native-prebuilt-linux-x86_64-1.6.10/klib/platform/linux_x64]

Any ideas on what that means or how to resolve it?
