https://github.com/rickclephas/KMP-NativeCoroutines are you able to actually set this up and run the app? it breaks my app every single time I import it

I’m trying to expose an extension function on

ByteArray

on

KotlinByteArray

in swift.

fun ByteArray.toUIImage(): UIImage = this.usePinned {
    val nsData = NSData.create(bytes = it.addressOf(0), this.size.convert())
    return UIImage(data = nsData)
}

I can’t see this function in Swift though. Is this not possible or am I missing something? How do you properly pass image data to swift from kotlin?

How can I configure the multiplatform tasks that are part of the plugin, so that yarn will not load eslint-scope-3.7.2 but a different version. The 3.7.2 that appears to come as part of the yarn build 1.22.10 that is part of the plugin, has a known vulnerability. I can't seem to fi d documentation on how to do this?

Is there a reason why the KMM plugin not being available for intelij IDEA?

We’re having some difficulties with thrown exceptions from the shared code that we handle in the iOS side. We annotate suspending functions in our domain/data layer with

Throws(Throwable:class)

and we log these errors to Crashlytics. Problem is, the error we get (when we cast it as an NSError) has a user info dictionary with a KotlinException entry, and it has a code of 0 and a domain of “KotlinException”. This causes all errors logged to crashlytics to be grouped under the same bucket. The Kotlin throwable has a message which looks something like this (this is formatted for readability, it’s still a string)

Exception in http request:
    Error Domain=NSURLErrorDomain Code=-1009 "The Internet connection appears to be offline."
    UserInfo={
        _kCFStreamErrorCodeKey=50,
        NSUnderlyingError=0x28035a940 {
            Error Domain=kCFErrorDomainCFNetwork Code=-1009 "(null)"
            UserInfo={

                _kCFStreamErrorCodeKey=50,
                _kCFStreamErrorDomainKey=1
            }
        },

        ),

        NSErrorFailingURLStringKey=SOME URL,
        NSErrorFailingURLKey=SOME URL,
        _kCFStreamErrorDomainKey=1
    }

I could try and parse this string, extract regex matches etc, but I was wondering if there is a better way. It seems like Kotlin packs all of the interesting stuff and concatenates their string representations and just stuffs it into the userInfo entry. I would very much have liked to get the actual error instance. How do people handle this?

One issue I've been having with multiplatform development is that I am no longer able to run anything from inside the IDE. Maybe there is some issue with the Gradle build script, but after switching my project to KMP I cannot run anything by right-clicking on a functions and selecting "Run" or "Debug" - instead I must setup a special task in Gradle and do everything from the command line. Has anyone else encountered this issue? How can I debug KMP code?

Hi all, i am working on kotlin multiplatform app and i have created two separate projects for android and ios, and inside android project i have setup the kmm shared module. Then i am importing the shared module in ios project in xcode by setting the hardcoded path for both framework search path and run script. And it was working perfectly. But now due to some issue, i had to import the project from git and created the project in separate directory on my macbook and then accordingly changed the paths in xcode as well. But now its showing build error there as following:-

Error: Could not find or load main class org.gradle.wrapper.GradleWrapperMain

Caused by: java.lang.ClassNotFoundException: org.gradle.wrapper.GradleWrapperMain

Important point: What is different that i have seen from my previous project(which was working) is that inside new android project's shared/build/ directory, no xcode-frameworks and bin folders found there, these folders are not available there inside new project.  I have been following everything from this link since the beginning for setting up the project:https://kotlinlang.org/docs/kmm-integrate-in-existing-app.html#connect-the-framework-to-your-ios-project. Guys Please help me with this. Struggling a lot with this. Thanks

Hi. Are there any convenient way for KMM to access network state for both Android and iOS? Looking to monitor connectivity lost/change. Considering that I am supposed to be a 3-rd party library.

Hi! I have a JVM library. We are now making it multiplatform. One of the features of the library is the different implementations. On the JVM, this is done via SPI (Service Provider Interface). Help, please, do you know a way to do the same for kotlin-js and kotlin-native?

Hi! I’ve got a large byte array (a bitmap) on Swift side inside UInt8[] array. How do I pass it to Kotlin? I have found this answer on Stack Overflow, but it looks very inefficient - every byte is copied in cycle. Is there a more effective way to transfer the byte array?

I get this error in a fresh KMM mobile project: Please, check that podfile contains following lines in header: source 'https://cdn.cocoapods.org'

I'm trying to add Stripe via cocoapods to my KMM project. I've added it via

pod("Stripe")

to my

build.gradle.kts

but now syncing the project fails with the task

':shared:cinteropStripeIosArm64'

producing the following error:

Exception in thread "main" java.lang.Error: /Users/paulweber/Development/Spenderino/shared/build/cocoapods/synthetic/IOS/shared/build/Release-iphoneos/Stripe/Stripe.framework/Headers/Stripe-Swift.h:722:10: error: no type or protocol named 'PKContactField'
    at org.jetbrains.kotlin.native.interop.indexer.UtilsKt.ensureNoCompileErrors(Utils.kt:192)

I can use Stripe inside Xcode with this configuration, but building my shared kotlin module fails due to the aforementioned task failing. I'm guessing this has something to do with the gradle task not having access to Apple's

PassKit

which is however needed for compiling the Stripe pod? Has someone successfully integrated Stripe in a KMM project or run into a similar error with cocoapods?

So I have a KMP module, with ios, mac, jvm, js targets. The mac source looks fine, but the iOS is full of Unresolved References for all iOS classes/methods. I am using the latest Android Studio and KMM plugin. Any ideas why this is happening?

Hello, I am getting this error on my newly created KMM project when i try to run the IOS app from android studio

Does anyone have working example of custom xcframework cinterop implementation? Context: Trying to achieve similar approach to firebase-kotlin-sdk, i.e. take custom iOS and Android libraries, add common code and publish it to maven for easy KMM consumption. Unfortunately copying their gradle configuration doesn't work for me, and tweaking it results in different kind of errors (e.g. linkDebugTestIos failures). Perhaps it's related to how xcframework is configured, I am not using Carthage or Cocoapods 🤷 Nonetheless would be great to see working examples of similar solutions if anyone has any.

Are there any good examples available yet using new Kotlinx Coroutines 1.6

runtTest

in

commonTest

tests? I have a basic test that tests flow which works if run for Android or JVM but for iOS target I'm getting following.

UncompletedCoroutinesError: After waiting for 60000 ms, the test coroutine is not completing

I just tried to create a new KMM project with Android studio and got this error when it tried to build:

'pod install' command failed with code 1.

Error message:

Please, check that podfile contains following lines in header:

How do fix this?

guys, do we still have to add this dependency to androidMain:

api("org.jetbrains.kotlinx:kotlinx-coroutines-android:$kotlin_coroutines")

in a kotlin multiplatform project where

api("org.jetbrains.kotlinx:kotlinx-coroutines-core")

is inside commonMain ?

Why is there no such a thing as Volatile for Kotlin Native?

Hi all, when using kmm, how to handle BigDecimal ?

Why isn’t the

iosSimulatorArm64()

target part of the

ios()

target yet? Same for

tvosSimulatorArm64()

and

tvos()

.

hello guys, please i need help with this. Whenever i add the ktor dependency to the iosMain in my build.gradle.kts(:shared), the ios app fails to build but after removing it builds. This is the shared gradle:

val iosX64Main by getting
val iosArm64Main by getting
val iosSimulatorArm64Main by getting
val iosMain by creating {
    dependsOn(commonMain)
    iosX64Main.dependsOn(this)
    iosArm64Main.dependsOn(this)
    iosSimulatorArm64Main.dependsOn(this)
    dependencies{
        implementation(Dep.Ktor.ios)
    }
}

And this is the error i get:

Anyone aware of a Multiplatform library to format (human readable) data sizes e.g.

? Must include JS. Used Package Search but nothing came up 🤷

I'm trying to figure out which tools work well with KMM and haven't found any clear answers. Do these tools work well with KMM? • Android Jetpack • Dependency injection (Koin?) Or, do they cause significant problems with KMM? And if they do, what tools are recommended for similar purposes?

🎁 In case anyone finds it useful, here's a ✨ Human Readable Data Size formatting function ✨ that uses only Kotlin Multiplatform Common API's. Just drop it into your common source set & go 😄 Other implementations I found 😒tackoverflow: either use string formatting or other functions not found in 'common Kotlin'; this gets it done with what's available. Welcome any suggestions for improvement!

Are there any multiplatform shared-resource library that can target js? I know of moko-resources, but they dont support js.

Anyone tried KMM recently, how was your experience? • How is new memory model? • Has tooling improved? • Has performance on iOS improved? • Where things are lacking currently?

Hello while working on multiplatform project, I am sharing mu compose UI between android and Web I have created a

composable

shared multiplatform module, inside that I have put some compose libraries as

commonMain

Android app runs fine, but when I try to run

./gradlew jsBrowserRun

it fails to resolve all the compose dependencies
