so I created a new KMP project, got some stuff up and working across Android & Desktop, and I want to add iOS now, which the project wizard didn't create anything for. Is there a good tutorial or anything for adding iOS to a KMP (not KMM) project after the fact?

Is Stately still the best option for a common

CopyOnWriteArrayList

?

Hi! I have a sealed interface in my Shared code. It has 2 inner data classes. Those are not being exposed to the iOS library.

sealed interface SomeInterface {
    data class SomeInnerClass(
        val internalObj: SomeInternalObj,
    ) : SomeInterface

    data class AnotherInnerClass(
        val internalObj: AnotherInternalObj
    ) : SomeInterface
}

🔴

SomeInterface.SomeInnerClass

is not exposed to iOS If I try the same, but using a class, it works:

sealed class SomeClass {
    data class SomeInnerClass(
        val internalObj: SomeInternalObj,
    ) : SomeClass

    data class AnotherInnerClass(
        val internalObj: AnotherInternalObj
    ) : SomeClass
}

🟢

SomeClass.SomeInnerClass

is exposed to iOS Is it possible to make the internal classes visible to iOS using an interface instead of a class?

what do people use for multiplatform logging?

Do you know some library multiplatform for calculating CRC32?

huh, as soon as i add

ios()

to my common gradle file, it starts failing to resolve my dependencies:

Could not resolve org.jetbrains.compose.foundation:foundation:1.1.0.
Required by:
    project :common

all of a sudden one of my multiplatform libraries decided that it thinks cocoapods isn’t installed when it definitely is. the strange thing is that another multiplatform library isn’t complaining. So I have 2 intelliJ windows open for two different multiplatform libraries. One of them runs “podInstall” without issue and the other one thinks cocoapods insn’t intalled. literally no code changes. one minute it was working, the next minute it starts giving this error. Any ideas? I’ve done invalidate and restart and restart the laptop even. I don’t really have anything to even go on here. It’s installed and it’s telling me it’s not installed. Where can I even look for a problem?

I've got an ios project hooked up and consuming my kotlin native code (using the direct method, not cocoapods) but it looks like only some classes get gen'ed into the shared framework header. For instance

fun LifecycleRegistry(): LifecycleRegistry = LifecycleRegistryImpl()

isn't referenced anywhere in my own Kotlin code, so it doesnt appear to be present in the header file. If i add a public variable w\ that type to one of my classes, then it does appear in the header. Is there anyway to force it to add everything to the header regardless of if it is in a public interface somewhere?

Aight one more, for the iOS source set in my common module, how do I get access to the platform apis? I see how I would include third party libraries via CocoaPods or a definition file, but not the built-in platform APIs

I've been reading and reading and reading docs and I can't figure out if kotlinx supports multithreaded coroutines in iOS without object freezing? Does it? Is it still experimental? It's hard to know if a piece of documentation is outdated or not and I find it all very hard to grasp, can someone enlighten me in the current state of things?

After upgrading android studio to Chipmunk Patch 1, Gradle to version 7.4.2 and android gradle plugin to version 7.2.1 I started getting these warnings: Unable to build Kotlin project configuration

org.gradle.internal.component.AmbiguousVariantSelectionException: The consumer was configured to find an API of a component, preferably optimized for Android, as well as attribute 'org.jetbrains.kotlin.platform.type' with value 'androidJvm', attribute 'com.android.build.api.attributes.BuildTypeAttr' with value 'debug'. However we cannot choose between the following variants of project :common:
  - Configuration ':common:debugApiElements' variant android-aidl declares an API of a component, preferably optimized for Android, as well as attribute 'com.android.build.api.attributes.BuildTypeAttr' with value 'debug', attribute 'org.jetbrains.kotlin.platform.type' with value 'androidJvm':

          - Provides attribute 'com.android.build.gradle.internal.attributes.VariantAttr' with value 'debug' but the consumer didn't ask for it

Am I doing something wrong?

I mean, a simple checkbox would've made this a lot simpler, wouldn't it?

hello folks. Can anyone help me with CRC32 calculation in common code??? Please, more details in 🧵

Am I correct that Kotlin does not support inherited annotations in multiplatform code? (Like

@java.lang.annotation.Inherited

in Java.)

in a multiplatform project gradle build (kotlin dsl) how can i create a JavaExec task that has the jvmTest classpath? in the jvm only build it was just

classpath = sourceSets["test"].runtimeClasspath

Can somebody tell me why my multiplatform project suddenly is able to use

java.time

inside of

commonMain

? I'm using

kotlinx-datetime

as a dependency.

I have 2 multi-platform library projects A and B where B depends on A and both Android and iOS depends on B. How can I make classes from library A visible to Android and iOS through library B?

I have a multiplatform lib and I added a new dependency, then I have an example android app that I use mostly for testing. This new dependency works well in unit tests but when I try to use the android app it gives me a

ClassDefNotFound

exception. How could I start debugging this?

So, what's the context around that seemingly random KMM survey question about how sad I would be if I were no longer able to use Kotlin/JS? 😁

hello, Does anyone tryed to enable context receivers in a multiplatyform module? I would like to enable it for android and common but I get always the error saying that i need to explicitly enable it 😕

I have a multiplatform project that compiles into JVM, IOS, JS and Android, There is one function in commonMain that is using a multiplatform library krypto, It works great on all platforms but on android there is an issue, I’d like to implement a specific implementation of this function for android source sets but for all other platforms I’d like to keep the one from commonMain, how can I do that? I’ve looked into expect/actual but there I need to define an interface and then add implementations for every other platform, but In my case I only want to “override” so to speak the android implementation, and for all other platforms implementation from commonMain works great so I’d like to keep that.

facing a weird bug in KMP project with jvm and js target • compileKotlinJvm build successfully • compileKotlinJs builds successfully • compileCommonMainKotlinMetadata fails with dependency resolution errors Anyone faced this issue before? What might the cause be? WA??

I got an

@SharedImmutable
private val backgroundDispatcher: CoroutineDispatcher = Dispatchers.Default

and it looks like that every Job started by

backgroundDispatcher.launch()

runs on the same NSThread. I use

1.6.1-native-mt

. The same code on JVM runs every job on another thread. Do I have to do something extra to get this parallel?

Hi! I’m having strange problem with an

actual

class. I do follow the example in KaMPKit. Although everything works fine in KaMPKit standalone project, in my project which is a separate project and implements shared lib can not resolve

actual

class imports in

androidMain

but resolves

iosMain

😄 Any thoughts about what the reason might be? Thanks in advance.

it looks like kotlin stdlib does not have anything similar to java's SortedSet, am I missing anything?

Hello everyone, we are experiencing problems trying to debug multiplatform code from ios using https://github.com/touchlab/xcode-kotlin from touchlab. In particular in xcode we are trying to use step into for jumping from the swift code to the kotlin code. Is it a supported feature? Thanks!

Hello, how do you integrate kmm framework with Xcode project? Static or dynamic framework? What's the best way? I have used static umbrella framework in our production project. But the Xcode project compile-time is long enough when I update kmm static framework. So I want to know if dynamic framework is allowed and compile-time is shorter? Or is there any other problem with dynamic framework? Thanks.

Hi, anyone has problem with KMM plugin and Android Studio that disable it?

Hi, I have a problem creating a archive of my iOS projet with a KMM framework in it. The error message a receive is “Invalid Bundle. The bundle XXXXX.framework does not support the minimum OS Version specified in the Info.plist.” The MinimumOSVersion is 9.0 in the plist and my project support iOS14 and up. If i manually remove the MinimumOSVersion then I can archive it but if I change it to something else like 14.0 it’s still does not archive. Is there a way with embedAndSignAppleFrameworkForXcode to remove this MinimumOSVersion?
