Hi there! Is there any KMM library available for checking the network connectivity? Tried https://github.com/ln-12/multiplatform-connectivity-status but it hasn't worked well in our project.

I'm trying to make use of

api("space.kscience:kmath-core:$version")

but it seems to lack a

iosSimulatorArm64

source set. Can I somehow patch that up on my end?

Im trying to upgrade my gradle to .kts, but I seem to have some issue with the publishing of my multiplatform library: old:

afterEvaluate {
    publishing {
        publications {
                kotlinMultiplatform { publication ->
                    artifactId = project.name
                    groupId = gradle.ext.group_id
                    version = gradle.ext.library_version
                }
            }
        }
    }
}

new:

afterEvaluate {
    publishing {
        publications {
                    getByName("kotlinMultiplatform") {
                        (this as MavenPublication).let {
                            artifactId = name
                            groupId = Library.group
                            version = Library.version
                        }
                    }
        }
    }
}

All the jars etc seem to be generated just fine, but on the new implementation I dont get a root folder for the artifact, even though kotlin documentation specifies:

Some repositories, such as Maven Central, require that the root module contains a JAR artifact without a classifier, for example kotlinMultiplatform-1.0.jar.
The Kotlin Multiplatform plugin automatically produces the required artifact with the embedded metadata artifacts.
This means you don't have to customize your build by adding an empty artifact to the root module of your library to meet the repository's requirements.

https://kotlinlang.org/docs/multiplatform-publish-lib.html#structure-of-publications What could I be doing wrong?

Can anyone point me to a resource explaining setting up ksp with kotlin mobile multiplatform? I am trying to add it for koin.

Hi, I’m trying to add a table in my sqldelight schema but the app doesn’t update the database schema I even try deleting the data and uninstalling the app but it still remain the old Schema, Is there a way to force the upgrade of the schema? (like the “version” in Realm) Strange thing is that if I check the generated class “DatabaseImpl” it has the correct generation of tables, and if I change the name of the database it works as intended (generate the new schema) but if I use the same name the table is not there 😕 . I’m using sqldelight 1.5.3

sqldelight{
    database("Database"){
        packageName = "package.name.datasource.cache"
        sourceFolders = listOf("sqldelight")
        verifyMigrations = true
    }
}

Any Ideas? The issue is happening on Android. Thanks !!

Is it somehow possible to gain access to Platform Specific APIs from a jvm target? I have a jvm app and I would like to have access to MacOS’s native notifications (display and hide notifications for example).

I'm trying to create a custom compilation for the metadata target, but I'm getting an error that says

Can't create custom metadata compilations by name

. I'm doing:

kotlin {
  targets {
    getByName("metadata") {
      compilations.create("testUtils")
    }
  }
}

I'm trying to do this because I have a

commonTest

sourceSet that has a mix of tests and utils in it. I also have a custom jvm compliation for benchmarks that relies on the utils in

commonTest

. I can't add

commonTest

output classfiles as a dependency because then it brings in the common tests, which I do not want. Any ideas other than creating separate modules for all of these things?

Hi. I'm planning to modularise my kmp library and I wish to replicate the same build configurations in

/module/build.gradle.kts

across all my modules. Whats the best way to do this? Do I have to use

buildSrc

in order to achieve this?

Is there someone with experience with Objective-C - Kotlin interoperability in KMM? I am trying to invoke an Objective-C function that takes a parameter with the following type:

CValuesRef<CPointerVar<ifaddrs>>

This supposed to be a pointer but I have no idea how to create something like that in Kotlin.

Hi, I have a strange issue with cocoapods integration that I hope someone can give some insight into. We've been working on a kmm project and development has been going well. Now we want to set up the analytics so in the

build.gradle

cocoapods

block, we added

pods("FirebaseAnalytics")

. Adding the pod work fine and Analytics is working, but now Xcode has lost all reference to my shared project, none of the autocomplete works and it's full of errors about none of my

shared

classes are in the scope. From my investigation, after gradle runs its magic, it's supposed to generates a framework of my

shared

module at path

build/cocoapods/framework

. Inside the framework, there's supposed to be a

shared.framework/Headers/shared.h

where all the

shared

module's headers are. But the issue is that after I add the

pod()

function inside the

cocoapods

block, the framework only contains a

placeholder.h

file inside the Headers folder which is only contains this single line

// Autogenerated placeholder header. Do not edit manually.

The strange thing is while Xcode is filled with errors, I can actually build and run the app perfectly fine. Also if I remove the

pods("FirebaseAnalytics")

, everything is back to normal,

shared.h

is back in the Headers folder instead of

placeholder.h

. Any ideas how to resolve this issue?

Hi guys, does anyone know the reason for the error?

hello new friends

i am working on a Kotlin Multiplatform web framework and am looking for people who are interested in collaborating / sharing ideas 🙂

I have same dependency for androidApp and commonMain I am getting Duplicate class error. How can I fix this?

WorldWind Kotlin 1.1.0 released! Start your KMP map application today with the first open-source multi-platform 3D globe SDK. A bunch of stability fixes implemented. https://github.com/WorldWindEarth/WorldWindKotlin/releases/tag/v1.1.0

Is there already some kind of consensus about translations sharing in multiplaform apps?

Hi all! Just published Multiplatform Paging, a library that packages AndroidX Paging for Kotlin/Multiplatform. It’s built to be a drop-in-replacement for AndroidX Paging, so extracting out shared pagination logic couldn’t be easier. Please check it out if you're interested!

Hello I am new to kotlin mpp and have been following the tutorial to build a ShoppingList full stack app. I am trying to use React routes but have issues importing it. Inside of gradle I use “implementation(“org.jetbrains.kotlin-wrappers:kotlin-react-router-dom)” as per the instructions located here. https://github.com/JetBrains/kotlin-wrappers/tree/master/kotlin-react-router-dom However in my Main.kt running “import react.router.dom.*” doesn’t work. Does anyone have an idea what I could be doing wrong?

@Jay Upadhyay did you sync IntelliJ with your gradle build? so that it picks up the new build settings

@Sam Gammon I think this may have been my issue. Thank you. I will follow up your advice.

@Jay Upadhyay you can always tell this is the issue if

./gradlew build

works, but IntelliJ doesn't find it

good luck! 🙂

Fixed: Thanks to https://kotlinlang.slack.com/archives/C3PQML5NU/p1666964189119009?thread_ts=1666957404.758489&cid=C3PQML5NU I am writing a kotlin multiplatform library, I have included the framework in my cocoapods block but when i build I get the following error

error: Signing for "gRPC-gRPCCertificates" requires a development team. Select a development team in the Signing & Capabilities editor. (in target 'gRPC-gRPCCertificates' from project 'Pods')

Hi, I am doing the tutorial to build a ShoppingList full stack app, and I was wondering how to add a class/id attribute for HTML on App.kt. For example,

h1 {+"Full-Stack Shopping List"}

-> I want to write something like this:

h1(classes="hello"){+"Full-Stack Shopping List"}

I realized that for id, I can simply write:

h1 {id = "hello" +"Full-Stack Shopping List"}

. I have researched and it seems like using kotlinx.html (https://github.com/Kotlin/kotlinx.html) might be the solution. However,

h1("hello"){+"Full-Stack Shopping List"}

doesn't work. Does anyone know how to add a class attribute specifically in the App.kt on the tutorial. (https://kotlinlang.org/docs/multiplatform-full-stack-app.html#build-the-user-interface)?

What are the different ways of importing iOS specific code into a multiplatform library project? I know we can use cocoapods but what if i want to use some github repo or custom local source ?

I’m trying to read resource files during unit tests. I have an

except

function like so :

internal expect fun readResourceFile(resourceName: String): ByteArray

This is the jvm implementation :

actual fun readResourceFile(resourceName: String) =
    File("./src/commonTest/resources/$resourceName").readBytes()

I wonder how I’m supposed to implement it for my js target? I tried to use this :

js("require('../../../resources/main/$resourceName')")

but it complains that the string must be a constant. And the return type is

dynamic

which doesn’t help neither

Is there a way to use Aspectj in kotlin without using Spring?

im getting a funny error when trying to setup my shared kmm module for ios dev, it seems to be looking fro watch support too. My swiftPackage config is:

    swiftToolsVersion(ver_swift_tools)
    targetPlatforms {
        iOS { v(ver_ios_deploy_target) }
    }
}
