Hey guys, I am reading this Creating your first Kotlin Multiplatform library. I updated the maven-publish Gradle plugin. After that I run the command .

/gradlew publishToMavenLocal

. I am getting error

Execution failed for task ':generateMetadataFileForIosArm64Publication'.

> java.io.FileNotFoundException: /Users/vmodi/IdeaProjects/AndroidModule/build/classes/kotlin/iosArm64/main/klib/AndroidModule.klib (No such file or directory)

I need to add chunking to some code that I was hoping to push down into commonMain. I have a web socket that blasts messages like a fire hose and I need to batch them by time or size. We have this logic implemented in Android already using some code that seems to be used widespread from Pin-Sho Feng. I believe that I'm not able to use that because timer is defined in kotlinx-coroutines-core-jvm. The compiler can't find it when I move the code to commonMain. Can somebody recommend a solution that would allow me to have my repository contain the web socket so that it can cache the messages in a local database? I'd like to have this repo used by iOS too.

Why most(99%) KMM examples use Jetpack Compose? XML is really dead?

Not sure if this is the appropriate channel, but hope you can help 🙂 After updating to Chipmunk (Android Studio), the editor editor suddenly states that there's an "unresolved reference" to one of my model classes (that's located in another module). I have two "core" modules (multiplatform with a JVM target), a shared (multiplaform with an Android target) module and my main android app module (standard Android module). The weird thing is that it builds and runs - it's just the editor that complains. Furhtermore, the references I have in the shared module to the core modules aren't complaining. And the references from the android module to the shared module is also fine. It's just that single reference from the Android module to the core module with my model classes. It wasn't an issue until yesterday when I updated to Chipmunk so I assume it's related to that. I tried downgrading gradle/AGP without any luck. Might just be a visual thing, but autocomplete is tottally broke when it comes to the model classes. Anyone else experiencing the same? Hope you'll be able to help - thanks in advance.

would I be able to use multiplatform for tizen and webos?

I may sound pretty vague but are there any samples or resources for KMM project Github Actions? :blob-sweat-smile:

Good morning! I’m creating a kmm library for my apps and ran into an issue, the external libraries are showing that I have java 1.8, even having selected java 11 on the project settings and also having the kotlin and java tasks set to use java 11 as the target and compatibility version, does anyone know what could be causing this?

Quick question: I have a big production-ready native iOS app for which I also want to develop an Android app. I really want to make sure the business logic is shared between these two projects, so KMM seems very interesting. On the Kotlin website I see that the KMM is currently classified as Alpha stage? Is there a roadmap/planning when you expect to classify this as Beta?

Is there anyone who can do me a favor? When I add the npm dependency for jsMain sourceset, all sourcesets cannot be distinguished by the IDEA.

Hi! I’m facing some weird behaviors using async/await on the iOS side to consume stuff from the shared module. It only happens to me on the Release version of the app. For example: In debug mode, if I turn off my internet connection and call a method from shared that does an API request, it emits an error. However, in the Release mode, that error is not being emitted. Does anyone here have ever faced this type of weird behavior?

Hi! I’ve been trying to build and distribute a KMM project on CI environment for iOS and trying to use the

linkReleaseFrameworkIosFat

gradle task to build the shared framework. However when I run it (both from the terminal or from the gradle tasks section of Android studio), I get this error.

class org.jetbrains.kotlin.gradle.tasks.FrameworkDescriptor cannot be cast to class org.jetbrains.kotlin.gradle.plugin.mpp.Framework (org.jetbrains.kotlin.gradle.tasks.FrameworkDescriptor and org.jetbrains.kotlin.gradle.plugin.mpp.Framework are in unnamed module of loader org.gradle.internal.classloader.VisitableURLClassLoader @334f46fa)

I can’t find any mention of this issue anywhere. Has anyone run into such problem? Any suggestions on what to check?

I have a class with width and height properties in Kotlin declared.

var width: Int = 0
var height: Int = 0

They turn to width_ and height_ in Swift. Do you have any idea why the underscore was added at the end of the property names?

@property (getter=width__) int32_t width_ __attribute__((swift_name("width_")));
@property (getter=height__) int32_t height_ __attribute__((swift_name("height_")));

Any help appreciated!

How do you guys implement Firebase in multiplatform project? Firebase push notifications, crashlytics etc.

Hey guys, Can somone help me on publishing library on maven repository. I am new in publish library. Actually my goal is to publish artifact in private repository. But I start from basic. I have knowledge to store

mavelLocal

. I want to learn more. Thanks

Hi, just for info: for use this library https://github.com/gitliveapp/firebase-kotlin-sdk i need add other configuration (exclude google json/plist) for use in test? I imported it in KaMPKit and when i start compile for iOSTest continually doesn't find something from Framework

Cross posting this here. Could you please help me. https://youtrack.jetbrains.com/issue/KT-52378/KMM-Xcode-iOS-project-integrates-two-KMM-frameworks-one-is-legac

I'm publishing a XCFramework that I create from Kotlin. There are several cases of functions and classes that are useful from using from Kotlin but not from Swift or Objective-C. Are there any compiler plugins that will strip classes/functions from the header file created for the frameworks. I still want the symbols there since they are likely used internally by the library, I just don't want them to be part of my public API. If there is not a plugin out there, any help finding information about creating a plugin that changes the header that gets created would be appreciated.

I know it’s a big ask, but KMM composite builds need to be fixed. This issue is causing red text and syntax errors all around our project. I cannot try out Live Edit, let alone Preview a lot of elements properly because of false errors coming from our shared KMM module. The number of YouTrack bug reports is making it hard to navigate or to find status or progress. Does anyone know if there will be any effort put into solving this soon? It sounds like it’s not even on a roadmap yet. https://youtrack.jetbrains.com/issue/KT-52172/Multiplatform-Support-composite-builds

I’m trying to add a foreign key through migration for my SqlDelight table as follows,

0.sqm

CREATE TABLE IF NOT EXISTS entry(
    ...
);

1.sqm

PRAGMA foreign_keys=off;
BEGIN TRANSACTION;
CREATE TABLE IF NOT EXISTS entry_temp(
    ...
    key INTEGER,
    FOREIGN KEY(key) REFERENCES ...
);
INSERT INTO entry_temp (...) SELECT * FROM entry;

DROP TABLE entry;
ALTER TABLE entry_temp RENAME TO entry;
COMMIT;
PRAGMA foreign_keys=on;

But upon running

generateCommonMainDBInterface

task I get an error for with the following stacktrace.

> A failure occurred while executing com.squareup.sqldelight.gradle.SqlDelightTask$GenerateInterfaces
   > Failed to compile SqlInsertStmtImpl(INSERT_STMT): [] :
     INSERT INTO entry(...)
     VALUES (?, ?, ?, ...)

java.lang.IllegalStateException: Cannot get reference table for psi type class sqldelight.com.alecstrong.sql.psi.core.psi.impl.SqlNewTableNameImpl

This

INSERT

statement is written in the

.sq

file and is syntactically correct. However if I don’t rename the table and use

entry_temp

as it is (with necessary changes in

.sq

file as well), the task runs successfully. Am I missing something here? :blob-thinking-fast:

I want to use this library to replace SharedPreferences in Multiplatform project. I want to store token from Firebase. Firebase needs you to create a service in Android side which you can’t put in commonMain. How can I access Settings from a service in androidApp? https://github.com/russhwolf/multiplatform-settings

[resolved]First time in KMP, i created my first project and have this problem.

'pod install' command failed with code 134.

Error message:

Analyzing dependencies

Please, check that podfile contains following lines in header:

source '<https://cdn.cocoapods.org>'

Please, check that each target depended on shared contains following dependencies:

I installed cocoapods with command

sudo gem install cocoapods

If I have an

expect fun test()

and 1 target, which already has a

fun test() {}

(and doesn't have the

actual

keyword), is that supposed to work, or does

actual

need to be specified?

I got a lot of

Can I let multiple targets, but not all, uses the same sourceset? How?

Hello Folks 👋 I have recently participated in several threads here, that convinced me, that it might be a good idea to organise a virtual meetup. The idea is that everyone can freely share his experiences/issues and future wishes for Kotlin Multiplatform in a relaxed environment and maybe we could just have some fun conversation. 🕐 5:00-6:00pm CET/Munich time :virtual-meeting: Multiplatform Community Meeting Monday, May 16 · 5:00 – 6:00pm Google Meet joining info Video call link: https://meet.google.com/hsb-vmdm-kgc Or dial: ‪(DE) +49 40 8081616930‬ PIN: ‪558 126 432‬# More phone numbers: https://tel.meet/hsb-vmdm-kgc?pin=4405620035258 Feel free to join and present your thoughts, or just mute and listen, either is just fine! Looking forward to it! Feel free to 😛lus1: , to announce that you would like to participate!

Thanks @Sebastian Sellmair [JB] for hearing us out and explaining some more technical challenges. Regarding the gradle sync being retriggered when reopening the project, I first noticed this in Android Studio: https://issuetracker.google.com/issues/232112721 Then I switched to IntelliJ, which has the same issue with a different underlying reason though: https://youtrack.jetbrains.com/issue/IDEA-294146/ Then I've tried deleting

.idea

&

.gradle

directories and then re-opening the project - but now no modules are listed at all: https://youtrack.jetbrains.com/issue/IDEA-294148/

What determines the value of

isCompatibilityMetadataVariantEnabled

in

kotlin-tooling-metadata.json

? I'm seeing it set to

true

in all of the dependencies that I use (e.g. coroutines), except for a library that I publish (e.g. portal), where it is

false

.

If my multiplatform library doesn't have any native targets, should there be a klib generated for it?

Is there any way to associate a

KotlinSourceSet

with a specific

KotlinTarget

? e.g.:

kotlin.targets.configureEach {
  kotlin.sourceSets.configureEach {
    // only do something with this source set if it is associated with the target 
  }
}
