Hello, everyone I am working with multiplatform project. For a long time I worked on Android part. But today I started to work with iOS part, I added :

dependencies {
                implementation "org.jetbrains.kotlinx:kotlinx-coroutines-core-native:$coroutines_version"
            }

to iosMain dependences because my project uses coroutines in common part. After that I changed graddlew to update graddle version. Then I run buildDependences task to build all dependences. Success, after that I tried to run XCode project but got error:

* What went wrong:
Could not determine the dependencies of task ':app:copyFramework'.
> Task with path 'linkDebugFrameworkIos' not found in project ':app'.

I went to IDEA and found that 'copyFramework' task depends on 'linkDebugFrameworkIos', but I didn't find it in graddle tasks list.

task copyFramework {
    def buildType = project.findProperty("kotlin.build.type") ?: "DEBUG"
    def target = project.findProperty("kotlin.target") ?: "ios"
    dependsOn "link${buildType.toLowerCase().capitalize()}Framework${target.capitalize()}"

    doLast {
        def srcFile = kotlin.targets."$target".compilations.main.getBinary("FRAMEWORK", buildType)
        def targetDir = getProperty("configuration.build.dir")
        copy {
            from srcFile.parent
            into targetDir
            include 'app.framework/**'
            include 'app.framework.dSYM'
        }
    }
}

I assume that when I upgraded graddle and changed graddlew it somehow removed this task. How can I fix it?

Hello, in an MP project for the iOS target we do not need to depend on a kotlin stdlib like we do for all the other sourcesets, what’s the reason for this?

Is there a way to specify the framework name generated by iOS target? The example project generates

main.framework

and I haven't found a way to change this. https://github.com/JetBrains/kotlin-examples/blob/master/tutorials/mpp-iOS-Android/SharedCode/build.gradle

Hi, is it safe to assume that the metadata.jar that is produced by the multiplatform plugin can be used as the compiled common sources?

Are there any library options for a simple single threaded observable/observer framework in kotlin multiplatform?

Could we have in the future a target for Dart? Thinking of Flutter for instance

Hi, is there a way the multiplatform project uses Int instead of Int32, I used it on Swift that Int types are Int32 in Swift. That causes some minor headaches.

hello fellow kotlin-folk: I created a kotlin native project in clion which seems to be using the multiplatform project plugin (using kotlinscript gradle), how would I go about adding a common module after the fact of creating a project without a common module?

Hi, I'm getting crash @ iOS @ Kotlin_Array_get

Hi, we have a dependency problem with our iOS target

Hi. I'm getting kotlin.TypeCastException, but only on iOS. How can I debug it?

has anyone run into

Duplicate JVM class name

issues working with `expect`/`actual`?

Hi! I'm unable to

import android.content.*

in my mpp project. What do I need to add to my

build.gradle

to make it work? thanks in advance.

Hi, running the main JVM method of my mpp project in intelij works exactly once. If I hit run again, I get a class not found exception for my main class. Cleaning the build resolves the problem and I can run the project once again before the class not found exception comes back. Is this a known issue? Are there any workarounds?

Hi. I'm getting

mutation attempt of frozen io.ktor.client.request.HttpRequestPipeline@8275c448

on iOS.

Anyone succeeding at meta-programming in MPP projects with kapt or other ways to codegen for all platforms? Kapt is JVM only and we rely on Arrow on annotation processing to generate code at the moment. Not being able to use kapt in MPP projects is currently not allowing to publish for JS and native. Any advice or recommendations are much appreciated. Thanks!

hey folks I’m a little confused regarding the versioning of KN. So if I use MPP Gradle plugin with Kotlin version

1.3.21

what version of KN it uses? Running the build with info I see

kotlin-native-macos-1.1.2

but I can’t figure out where is this configuration comes from? And how for instance to configure MPP plugin to use different KN version (I saw from change logs that new `1.2.0`one is available)

Hi, can I depend on kotlin-js-wrappers to create React components in a multiplatform project? When I added the dependency to my JS/Node target I couldn’t import RComponent for instance

Hi, I have a mpp which uses kotlin 1.3.30-eap-45 and coroutine 1.1.1, I got these two warnings when run compileKotlinIos

The compiler versions don't match either. Expected '[1.2]', found '1.1.1-release-6082'

,

kotlinx-coroutines-core-native.klib. The abi versions don't match. Expected '[8]', found '5'

build failed after the two warnings

Could not find kotlinx-coroutines-core-native.klib

Hi, I have a multi-module multi-platform project and am trying to get the gradle configuration to work. Right now I'm just trying to convert 1 sub-module over to a multi-platform module. Specifically I am using 1.3 DSL with source sets. I have moved my existing code out of src/main/kotlin and into src/jvmMain and attempted to configure a jvmMain source set to compile those files. I have tried adding the source set configuration to both the root project and the module with no success. No errors, just the files don't get compiled. Its like nothing is looking at the src/jvmMain directory and is still looking at src/main/kotlin.

I'm trying to call a function from the windows platform libraries:

BCryptGenRandom

. At link time, I get

undefined reference to 'BCryptGenRandom'

. Here are the linker settings I have for my mingw test target:

targetFromPreset(presets.mingwX64, 'mingw') {
    compilations.test.linkerOpts '-Wl,--subsystem,windows,-L"C:\\Program Files (x86)\\Windows Kits\\10\\Lib\\10.0.17763.0\\um\\x64\\bcrypt.lib"'
}

I think I may have overdone it with the full path to bcrypt.lib there, but I'm trying everything. Any advice here would be appreciated! First time attempting to get my K/N code working for mingw. Thanks!

Hey all I’m starting to create multiplatform libraries in Kotlin and I’m having trouble with integrating KTOR into the project. I’ve found several examples of multi gradle project projects that do it, but I can’t figure it out in my single gradle project. Obviously my gradle game isn’t strong. Can anyone point me in the right direction?

When creating a multiplatform project, I have .java files in the jvmMain and jvmTest source sets. However, when building the project these files seem to be ignored and only .kt files get compiled. Is there something special I need to do to get the multiplatform configuration to also compile java files in the jvm* source sets?

Hi guys, I would like to get the package name of a class using the kotlin common library. Does someone know if we can do this? For example, when using jvm we can do something like:

java.util.Date().javaClass.

package

.name

but can we do something similar to get the same result with

stdlib-common

?

e.g. javascript doesnt have packages hence that's not possible for a jsTarget so there is no common way

Hi all. I found the problem on iOS 32 bit devices with our Multiplatform application. Everything work fine when we testing in debug build, but It always crash when launching with Testflight version. Have anyone encounter this kind of problem before?

Hello, does anyone know how I can use js externals in the js target of a multiplatform project? I would like to build not only a JS library but a React library, not only a JS lib to be used in a React app (to be able to build relevant React UI Components as we can build views the same way for Android libs and for iOS frameworks) ?

I notice that when I update the headers in an obj-c framework used through cinterop, I have to delete the build directory before it will regenerate the bindings (using intellij)

I'm getting an error that a class has been redeclared while running unit tests. If I do a

clean

it is fine until I make a change and rerun my tests. When I run with

--info

it appears that one of the files is being detected as modified twice.

This is using eap 45 if that matters. The same issue happened under eap 11 and the latest stable as well .
