So my code auto-complete and highlighting isn't working for

iosMain

. So far I've managed by just guessing names and such, but I'm wondering how do I actually get this working on a Mac? Any ideas?

Still having trouble linking binary framework from KMM to my iOS app. Tried default “pack for xcode” task, installing as a Podfile, and can’t seem to import and reference it from within the iOS app still. Anyone have any tips what worked for them with larger modularized iOS apps?

Hi, after the latest xcode update, I started getting this error in multiplatform mobile: The following build commands failed: Ld /Users/me/dev/android_projects/myproj/build/ios/iosApp.build/Debug-iphonesimulator/iosApp.build/Objects-normal/arm64/Binary/iosApp normal arm64 edit: error: The linked and embedded framework 'shared.framework' is missing one or more architectures required by this target: arm64. (in target 'iosApp' from project 'iosApp')

when using "suspend" functions in interfaces (not implementation) for common shared code. How is that "suspend" qualifier translated for iOS code implementing that interface?

Anyone know why I might be getting this error/how to fix?

I'm new to gradle and kotlin. I am struggling to understand how things interact. I have an MP project using ktor. I have successfully been able to build and run it using docker. I am not able to get my dev environment working. I am running the server using

run

and

installDist -t

, but the js is not served. I have found that if I manually copy the js files to

${buildDir}/processedResources/jvm/main

they are served. First I don't know that this is the 'correct' place for them when using

installDist

. Second for the life of me I can't seem to figure out how to get gradle to do a simple copy of the files to that dir. Are the js files supposed to be in that dir, and if so what would be a good or the proper way to make that happen?

Hi folks! Here is a quick question that will help us make Multiplatform better 🙂 Do you use jvm target in your Multiplatform projects? And, if yes, what is it for? 1️⃣ - Yes, for backend 2️⃣ - Yes, for desktop 3️⃣ - Yes, for other purposes 🇳🇴 - Don’t have jvm target in any of my projects

I was looking through this documentation looking for information on how to run KMM on an iPhone and not a simulator. Honestly, the docs above have me a little lost. In the past (With Koltin Native libraries) I modified the

packForXCode

function to pack a “fat binary” is that still the appropriate action?

I’d would like to share another interesting finding for KMP. I started to dig into

Kotlin/React

, and I realized it’s really simple to make components, using

Kotlin-DSL

HTML elements. I have started to create Web component functions that have exactly the same API of JetpackCompose composables (e.g. NavigationBar, NavigationItem). So, I can now build a webApp with Jetpack composables, still using Kotlin! It’s really awesome. I believe someone (maybe JetBrains itself) will eventually extend JetpackCompose to web, because it makes a lot of sense. I can see in the near future we will just have 2 UI frameworks:

JetpackCompose

(for Android, Desktop and Web) and

SwiftUI

(for iPhone, iPad, Mac, etc.). I don’t even think React will last, because JetBrains already gained so much expertise that they can easily write their own efficient web reactive framework in Kotlin/JS, based on

StateFlow

using JetpackCompose components for the UI, bypassing React completely. So, my suggestion for everyone is to really start learning JetpackCompose and SwiftUI, because this is going to be the base for any app of the future. All the rest will become legacy.

Hi guys. I am an android developer and in my company we are evaluating pros and cons of using Kotlin Multiplatform for all the new developments. We are developing a sample app (a shopping cart) that runs already on iOS and android but also we want to use the same business logic for the web (ideally WebAssembly). I'm not a web developer and I'm struggling to understand how to demo the WebAssembly version. Is there a hello world example that shows how to create and use WebAssembly from a Kotlin multiplatform project? Thanks in advance!

when using directory structure src jvmMain/resources jsMain how does one get a resource from src/jvmMain/resources?

javaClass.getResourceAsStream("blah.txt")

doesn't seem to work when using that directory structure, works fine when it's a normal

src/main/resources

structured project

Is it possible to create a Multiplatform library and publish it in Cocoapods? We are aiming to create a library that will ease an usage of our API by hiding endpoints behind library API. We want to write two separate libraries to support both iOS and Android. I thought that maybe it would be a good use-case for KMP, but I’m not sure if it will be possible to publish it in Cocoapods to let iOS developers easily integrate the library

I have added the Cocoapods plugin to my KMP project as described here https://kotlinlang.org/docs/reference/native/cocoapods.html. But the resulting .podspec file contains a line that looks like this:

"$REPO_ROOT/../../../../../../private/var/folders/ps/l3tx8c517t19l8p14jq3zvsh0000gp/T/wrap12070loc/gradlew" -p "$REPO_ROOT" ::syncFramework \

Most other generated podspecs I have seen in sample projects look like

"$REPO_ROOT/../gradlew" -p "$REPO_ROOT" :core:syncFramework \

I am concerned it refers to a temporary folder on my machine which may disappear in future. Does anybody know what the problem may be?

I have a KMP multi-platform library for Java-Swing, Android, iOS. There is no problem on Java-Swing, iOS, but an error is reported when used on Android. Has anyone encountered this kind of error?

Hi, I have a jvm project which I’m trying to turn into multiplatform, as I want to extend that to other platforms and there is things I’m able to share. The problem is, my main jvm target (named

app

), not multiplatform, is not recognizing the code from the multiplatform module (named

shared

). Gradle sync is fine, so I imagine the problem is not on there. app/build.gradle.kts:

plugins {
    kotlin("jvm")
    application
    id("org.openjfx.javafxplugin") version("0.0.8")
    kotlin("plugin.serialization")
}

dependencies {
    <other jvm deps>

    implementation(project(":shared"))
}

group = "group"
version = "1.0-SNAPSHOT"

application {
    mainClass.set("pac.kage.MainKt")
}

javafx {
    version = "12"
    modules = listOf("javafx.controls", "javafx.fxml", "javafx.graphics")
}

tasks.withType<JavaExec>().configureEach {
    doFirst {
        println("Desktop classpath: ${classpath.asPath}")
        jvmArgs = listOf(
                "--module-path", classpath.asPath,
                "--add-modules", "javafx.controls",
                "--add-modules", "javafx.fxml",
                "--add-modules", "javafx.graphics"
        )
    }
}

tasks.withType<Test>().configureEach {
    useJUnitPlatform()
}

And the shared/build.gradle.kts:

plugins {
    kotlin("multiplatform")
    id("kotlinx-serialization")
}

kotlin {
    jvm {
        val main by compilations.getting {
            output
        }
    }
    sourceSets {
        val commonMain by getting {
            dependencies {
                implementation(kotlin("stdlib-common"))
            }
        }
        val jvmMain by getting {
            dependencies {
                implementation(ExternalDeps.jipes)
                implementation(kotlin("stdlib"))
            }
        }
    }
}

I notice that JVM tests produce test result files in binary format. is that expected? my build server (bamboo) expects xml.

Too add to the list of questions. I am working on a kotlin multi platform library (only android and js for now), I have the library setup following what I think is latest guidelines but when I am trying to import the library into an android app through mavenLocal(), so not pointing to the project, I am getting the following error

Unable to resolve dependency for ':app@debug/compileClasspath': Could not resolve tech.ctawave.cmcd:cmcd-android:0.0.1.

Has anyone run into this? gradle 6.6.1, kt 1.4.10, and I have set

android {
   publishAllLibraryVariants()
}

within the library gradle. Any help is appreciated.

Does anyone know of an example of an opensource multiplatform project that shares navigation state through Multiplatform?

is there a way to get the Test task which corresponds to the jvm test compilation through the DSL? Or should I do name-based lookkup?

I have an issue that if I run android instrumentation tests the

androidTests

are compiled and running as well. Which is bad because I don't want this 🙃 . can I somehow exclude the

androidTest

sourceSet from the

androidAndroidTest

sourceSet? I tried already multiple things e.g. setting the

srcDris

of

android.sourceSet.androidTest.setSrcDirs()

but it seems they will always execute them. Regardless of what I put into the

srcDirs

.

I thought I had this Ktor networking with an MVP architecture working on iOS, but now I’m getting the following exception when trying to dispatch the result on

Dispatchers.Main

. Anyone else running into an error like this?

Hello everyone. I've been playing with multiplatform a bit and I'm wondering if anyone has some insight on the pros/cons of using

expect/actual

vs using an interface. I'm especially curious if there are use cases for

expect/actual

that can't be solved with an interface or are obviously better suited to the

expect/actual

pattern. I asked a question on the forums, but it didn't get any traction.

Are there any popular multiplatform client-side networking libraries other than Ktor?

Regarding support for calling suspend functions from Swift/Objective C.....I think this was asked here before but don't remember seeing an answer.....is anyone aware of how this is implemented under the good, and what is setup for example regarding dispatcher used and cancellations? I think many projects are still rolling their own approach to this primarily so they have control for example of lifecycle aware cancellation.

i have been having issues with a multiplatform project where a JVM module depends on a multiplatform module (targetting jvm and others). the JVM module is unable to see the public classes from the multiplatform module. I have created a bug here but if anyone has advice i'd appreciate it https://youtrack.jetbrains.com/issue/KT-42227

Does the kotlin stdlib provide a way to get the current timestamp, or am I imagining that that was added?

Hi，guys Can I use KMP(kotlin 1.4.10) with AGP 3.1.2 in the Android project？

Anyone had issues with

SqlDelight 1.4.3

native

dependency? Can’t seem to resolve

NativeSqliteDriver

, while

AndroidSqliteDriver

worsk well. Kotlin

1.4.0

Hi guys, is it possible to share resources (strings, dimens, drawables) with kmp?
