Hi folks 👋 I'm trying to add multiplatform support slowly to a relatively large Android codebase and have started with trying to convert some pretty foundational modules to

multiplatform

type from

jvm

or

com.android.library

. This has been working alright, but I recently ran into a problem when when I tried to introduce a dependency on a

multiplatform

module (with a

jvm

target) in a

jvm

module; Android Studio fails to resolve classes defined in the

commonMain

sourceset of the

multiplatform

module while inside the

jvm

module. However, everything compiles and packages fine from CLI so I'm wondering if this is an Android Studio bug. I have a sample project exhibiting this - but am wondering if this a known limitation or if anyone else has experienced this before.

Kotlin objects seems not releasing when created in swift code. I have a sample kotlin class `class Test {}`:

var test: Test?
weak var testW: Test?

func f() {
	testW = Test()
	print(testW) // non nil, unlike Swift class instance. 
	DispatchQueue.main.async { [weak self] in
	    print(self?.testW) // now nil, kind of ok
	}
}

func f() {
	test = Test()
	testW = test
	DispatchQueue.main.async { [weak self] in
	    self?.test = nil
	}
	DispatchQueue.main.asyncAfter(deadline: .now() + 1) { [weak self] in
	    print(self?.testW) // not nil, seems it's not gonna be released, we have a leak
	}
}

Why in the second case it not get’s release at all? It shouldn’t be captured by the block.. How can I release a kotlin object?

My module is for ios/android. I’ve got an error

IncorrectDereferenceException: illegal attempt to access non-shared ...

the object is created in

commonMain

part of the code, on a background thread. if I switch to main thread on kotlin part it works fine. but if I switch on iOS one, this crash occurs on access to the object. looks like

freeze()

is only available from ios part. Or am I missing some imports? How can I freeze an object in common code?

Hello folks, I am following https://kotlinlang.org/docs/mobile/create-first-app.html tutorial and am wondering if there is a way to add tvOS target as well. I am an iOS/tvOS developer with limited understanding for gradle build system so please bear with me. Also if this is not the right channel please point me to the right one, thanks.

In java exists some library with some class and interface. I’ve created except/actual interface in kotlin-multiplatform. And my interface is the same as jvm interface. Can I join my expect kotlin interface and jvm actual interface/class?

@alex009 any plans on adding macOS target also to moko-resources?

Hello everyone, is there a way to use string resources in shared models? For example, in KampKit in BreedModel instead of writing

return "Unable to download breed list"

in code, I want to write something similar to android's

return getString(R.string.download_error)

, so that it's easier to edit those strings in one common file

Hello guys , what is the best way to use Native libraries in both Apps , however there is the same lib implementation in both platforms Swift And Java (Libsodium)

Hey everybody, I am trying to add Jetpack Compose to my KMM project and specifically the Android app, however it is not cooperating. I get this error:

java.lang.IncompatibleClassChangeError: Found class org.jetbrains.kotlin.ir.declarations.IrModuleFragment, but interface was expected

. I think it has something to do with incompatible versions of Kotlin or some dependency, so I am trying to follow the example given by the KMM sample docs. Does anyone know which direction to look for a fix?

Hi folks, anyone knows if there is a Gradle plugin or a library for KMM to share vectors between Android and iOS apps?

Hello, I hope everyone is doing alright…I am quite new to KMM and I am struggling with creating a fat-jar w/ Shadow plugin. I do not really know how to add the task and then run it. Even though I have already added it in shared gradle and Synced project, it does not appear in the right side bar in shared tasks. May anyone give me a bit of help? thank you all 🙂

What is the difference between specifying jvmTarget with

kotlin {

   targets {
      jvm {
         compilations.all {
            kotlinOptions {
               jvmTarget = "1.8"
            }
         }
      }
   }
}

and

tasks.withType<org.jetbrains.kotlin.gradle.tasks.KotlinCompile>().configureEach {
   kotlinOptions.jvmTarget = "1.8"
}

Hi I am new to KMM. After using cocoapod to add an external dependency. Trying to import using

Any help ?

Trying to summarize the difference between the apps of the “past” and the apps of the “future”:

Is it possible to exclude a native source set for tests? I’m using kotest assertions but it has no support for watchosArm32. So gradle fails because it’s trying to look up that dependency. Therefore I want to exclude that one in tests.

How can I disable

kotlinMultiplatform

 MavenPublication? I have a android project :cabinet, that depends on multiplatfom project :cabinetcore through

api project(':cabinetcore')

. When I try to publish :cabinet I've got this error. I don't need

kotlinMultiplatform

publication, only

release

(which is mine publication). How can I disable its automatic creation?

Hey, I am trying to add a pod dependency in my KMM project but I am getting an error when I am syncing

Executing of 'pod gen --platforms=ios --gen-directory=/Users/atripathi/<Project Root>/shared/build/cocoapods/synthetic/iosArm64 dogtag.podspec' failed with code 1 and message:

Did you mean: env?

cocoapods {
    frameworkName = "shared"
    pod("Connectivity")
}

I should also specify here that the first step mentioned here https://kotlinlang.org/docs/reference/native/cocoapods.html#install-the-cocoapods-dependency-manager-and-plugin is failing for me when I run the command so I used`brew install cocoapods`

my project is working fine on iOS when I remove pod() dependency. I am kind of confused here where things are going wrong

Hi everyone. I'm gonna start working on a KMM project next week and I'm worried about what's the appropriate DI framework to use. So far, I've seen most of the people are using Koin or Kodein. I don't have any real experience with any of them. Does anyone know which one's better suited for KMM and why? I've couldn't find any good article about it.

Someone here can help me?

We're having issues with building a shared framework:

Both watchos-armv7k and watchos-arm64_32 represent two equivalent library definitions.

We're building the framework like this:

xcodebuild -create-xcframework \
-framework ios/build/xcode-frameworks/iosArm64/SharedCode.framework \
-framework ios/build/xcode-frameworks/iosX64/SharedCode.framework \
-framework ios/build/xcode-frameworks/watchosArm64/SharedCode.framework \
-framework ios/build/xcode-frameworks/watchosX86/SharedCode.framework \
-framework ios/build/xcode-frameworks/watchosArm32/SharedCode.framework \
-output "$XCFRAMEWORK_DESTINATION_DIR"/SharedCode.xcframework

Did someone manage to get arm32 and arm64 working together for kotlin native on ios / watchos?

Has anyone managed to add

SQLCipher

? Went through example: https://github.com/touchlab-lab/KaMPKitSQLCipher . Project actually builds on Xcode and works properly, but now I am having problems with

publishToMavenLocal

. When I run

gradlew publishToMavenLocal

this error is getting thrown:

Execution failed for task ':KME:cinteropSQLCipherIos'.
> Cannot perform cinterop processing for module SQLCipher: cannot determine headers location.

Following yesterday’s post and “heated” thread discussion, which was really helpful, I am now presenting a new diagram, which hopefully clarifies the points and removes the confusion. @jw made very meaningful observations, by pointing out that architecturally there is no difference at all between Declarative and Imperative UIs. You can apply MVI/unidirectional data flow in exactly the same way, for both. My yesterday’s diagram was indeed confusing, by hinting a unidirectional data flow just for the Declarative UIs. But there is an important difference between Declarative and Imperative UIs, and that is cohesion. In Declarative UIs, you just have 1 layer (Compose/SwiftUI), while in Imperative UIs, you have 2 layers (one of Kotlin/Swift code, and one of XMLLayout/InterfaceBuilder). This also means that each UI component introduces an extra relationship (coupling) between the 2 layers, which needs to be managed, with extra boilerplate code. Android has been trying to minimize this problem by introducing the ViewBinding, but the same mechanism doesn’t exist in iOS InterfaceBuilder, where the coupling between the 2 layers needs to be kept updated manually. Declarative UIs don’t have this low-cohesion issue, as the data can be applied directly on the UI layout, without an extra middle layer. This removes a lot of boilerplate code and clearly speeds up development.

Multiplatform project to implement server side jvm and client side android and jvm Is that possible it mean with two jvm targets

what is the difference between this channel and #kotlin-multiplatform 🤔

Hi folks, there is any library to help with i18n for KMM project?
