I have two targets and probably add more for native, tho ktor doesn't support that thing I want to use on native thats why I wanted to create seperate source sets for them but can I somehow make JS and JVM depend on the same implementation (so expected classes)?

Hello. Using the KMM plugin version 0.3 in AndroidStudio Chipmunk Canary 5 on Windows with the installed kotlin plugin of 1.6.0-rc2 allows to create a new kmm project now. While i can launch the freshly created Android app, the IDE marks the shared code in the

androidApp

module as "can not find". Is there something not working just yet?

Is it hoping for too much to want to see Kotlin classes from the common module in the variables window in the XCode debugger?

hi all, i’m going to start a multiplatform project. Targeting Android and Desktop now, ios shortly after. Is https://kotlinlang.org/docs/kmm-setup.html up to date?

Does anyone know the Intellij Idea youtrack issue URL or number for the problem with the IDE showing a false syntax error on any usage of an actual fun that doesn't specify a parameter with a default value in the expect definition? I've got a number of these and would like to start watching the issue that must be out there, but my searches are not finding it. To clarify, here's an example of the defect with a constructor, same thing happens on expect/actual fun:

expect class Anything(
    arg1: String,
    arg2: String = ""
) { ... }

actual class Anything(
    arg1: String,
    arg2: String
) { ... }

val x = Anything("x")

Every usage like this compiles fine in gradle and runs fine, but the IDE wrongly shows the assignment statement as a syntax error. The IDE inspection is going by the actual syntax which is not allowed to duplicate the default value defined in the expect. I have enough of these that the IDE defect is making me never want to use arguments with default values in an expect class again :-)

Hi all, pretty new to ios kmm development. I’ve recently migrated my project from old

packForXCode

to

embedAndSignAppleFrameworkForXcode

, and ever since all the kotlin sources in my swift fails will

error: ambiguous use of 'myKotlinClass'

Am no longer able to jump to definitions of any of my kotlin objects - and pretty sure something went wrong with the new linkages. Is there a way to debug this? using kotlin

1.5.31

Is there support for gRPC in kotlin multiplatform ? anyone ?

how do I fix missing javadoc jar errors on maven central?

Do we have any support for specifying Java Modules (Jigsaw) in a KMP JVM target? I'm compiling against Java 11 and need to use an AWT class from my desktop (JVM) target and it's not on the classpath due to being separated from the main SDK as a module.

Can anyone help out with the following error I am getting in sqldelight for nativeMain desktop containing all three(mac, linux and mingw) as targets? Following is my declaration in source sets for nativeMain

val nativeMain by getting {
            dependencies {
                implementation("io.ktor:ktor-client-curl:$ktorVersion")
                implementation("com.squareup.sqldelight:native-driver:$sqlDelightVersion")
            }
        }

Hey folks, I am trying to use

native.cocoa

plugin as described here: https://kotlinlang.org/docs/native-cocoapods.html#install-the-cocoapods-dependency-manager-and-plugin I’m just trying the code snipped from the docs to use

AFNetworking

inside iOSMain (as described in the docs).

kotlin {
   ...
    cocoapods {
        summary = "Some description for the Shared Module"
        homepage = "Link to the Shared Module homepage"
        ios.deploymentTarget = "14.1"
        frameworkName = "sharedClient"
        podfile = project.file("../iosClient/Podfile")

        pod("AFNetworking") {
            version = "~> 4.0.1"
        }
    }
    ...
}

The problem I am facing right now is that

cinteropAFNetworkingIos

fails:

> Task 😒haredClient:cinteropAFNetworkingIos Exception in thread “main” java.lang.Error: /var/folders/n9/5pkml05d7mn3xzdyty8cx5380000gn/T/3707914287112298431.m1️⃣9: fatal error: could not build module ‘AFNetworking’

I think it is more of a cocoa pods issue on my local machine, but I don’t really know how cocoa pods works exactly under the hood. I think cocoa pods did not download AFNetworking. (In a plain iOS / xcode project (not kotlin multiplatform app) I have used successfully cocoa pods, so I think it is fair to assume the required cocoa pods gems are installed on my machine.) Could anyone please point me in the right direction?

My method takes a

val requestSystemPhotoLibraryAccessPermission: suspend () -> SystemPhotoLibraryAccessLevel

suspend lambda. What is the correct way to call this in Swift?

requestSystemPhotoLibraryAccessPermission: {}

gives me an error as soon as I add the suspend keyword:

Argument type '() -> ()' does not conform to expected type 'KotlinSuspendFunction0'

What do I need to change? I don't understand that from the docs. 🙈

Can I create a Flow in Swift code if I have a parameter like

val requestSystemPhotoLibraryAccessPermissionFlow: () -> Flow<SystemPhotoLibraryAccessLevel>

? Or is just collection of a Flow in iOS code possible?

Accessing iOS files in KMM? I thought I'd seen comment (here) that Kotlin file access works, but I can't find any reference to it. Otherwise I'm trying to use NSFileManager and currently struggling with error returns from file access functions. Can anyone point me in the right direction (please)?

Hi, I am trying to understand how to avoid the InvalidMutabiltyException in following scenario: I have a ReconnectionManager that I want to be able to try and execute the

reconnectFun

. The idea is to trigger that function after some delay (which is incrementing from one attempt to another). The

reconnectFun

is passed from the parent class that is responsible for network error listening. I understand that my problem is that I mutate the

attempts

from with in the other thread, as well I call the

reconnectFun

but what is the proper way of doing something similar?

internal class ReconnectionManager {
    private var attempts = 0
    private val dispatcher = CoroutineScope(Dispatchers.Main + SupervisorJob())

    fun reconnect(reconnectFun: () -> Unit) {
        dispatcher.launch {
            delay(attempts * 1000)
            withContext(Dispatchers.Default) {
                attempts++
                reconnectFun()
            }
        }
    }
}

What is the current recommendation for having shared viewmodel logic between Android and iOS? Is https://github.com/icerockdev/moko-mvvm a good idea? I'm interested in having automatic coroutine cancelation when viewmodel gets destroyed and easy Jetpack Compose/SwiftUI integration.

I'm giving the new KMM plugin a try, I'm on windows, and if I create a project with cocoa pods support, it fails to even sync the gradle script on windows, because

pod

can't be found. I even went through and installed cocoa pods on windows and it can't find it. Does anyone have an experience with KMM w\ cocoa pods support on windows?

Problem #2: I created a new project (without cocoa pods support), but with Kotlin 1.6.0 and latest KMM plugin, and it seems confused about the common source sets. when using the Android view in the project browser, all of the modules under shared actually point to the

androidMain

source set

So I'm looking at the various KMM Architecture libs out there, is there any clear preference emerging yet on what most people use for defining their screens and navigation and such?

Hey lovely people, I am currently playing with some tools to generate source code...unfortunately they of course do generate Java... The question, which pops up now, is there a converter which can be integrated with Gradle to convert Java to Kotlin?

Has anyone here seen 

warning: Cannot find annotation method 'xi()' in type 'Metadata'

 style errors when using a kmp-jvm library from a java project? I kinda thought using the 

java

 and 

java-library

 plugins would make things "just work"

I don't really understand how to read / write files in okio 3 multiplatform (specifically on ios). All examples show how to do it using

FileSystem.SYSTEM

which is only available on `jvm` . It's like everything is there when you have

FileHandle

or

Sink

, but the first step is vague. Any hints?

Hi guys, I have noticed that when we produce a XCFramework for our shared code, the

ios-arm64

architecture folder is ~4 times larger than the

ios-x86_64-simulator

. For example for a really small project the

ios-arm64

folder is ~30MB and for a large project it’s ~75MB. Hint: we have tried to produce the XCFramework with both the native plugin and the multiplatform-swiftpackage plugin but we got the same size. Have you noticed anything similar? Is there a way to reduce its size?

When I change the shared module, what Gradle task can I use to rebuild the shared Framework for XCode to notice the changes?

anyone here use Koin for multiplatform projects? I'm doing some KMM prototyping and am woundering if I can use Koin to inject in my Swift code

Does someone have experience with sub modules with kotlin multiplatform ? (Eg : multiple modules in commonMain) Having a rough time setting it up with Intellij IDE. Thanks

Hi, guys! KMM is wonderful. Unfortunately, I’ve stumbled to a new obstacle. We need to unzip files on iOS. I have added ZIPFoundation library as CocoaPods dependency to KMM project. ZIPFoundation implements zip archive extraction as an extension to FileManager. Like this.

let fileManager = FileManager()

fileManager.unzipItem(at: sourceURL, to: destinationURL)

As far as I know, there is no access in Kotlin to Swift’s FileManager. Instead we have an access to NSFileManager only. So I’m not able to unzip because FileManager.unzipItem() cannot be called from Kotlin. Is there a workaround for this problem?

Hello, everyone. Just wondering what people do debug:

Task 'embedAndSignAppleFrameworkForXcode' not found in project ':shared'.

Adding

--debug

or

--stacktrace

to the task doesn't really help. I usually have to just randomly change things till it starts working. Is there a way to know the specific reason for the task failing. I know for a fact that it's generated when run from

XCode

but that's about it. Any debugging tips? 😅 Thanks in advance. Also. Is the source code available on Github? 🤔

How can we create sub modules like we can easily do on JVM (not multiplatform) projects? For instance, in the photo the module is recognized as a directory even though I have the include in my

settings.gradle.kts

Thanks
