If I have a multiplatform project, and have multiple jvm variants, and I have a jvm module in the same gradle project, how do I include a specific variant of the multiplatform project as a dependency?

When I run test via Run button in Android Studio I got Exception “No runnable methods” Can I run and debug test in multiplatform ?

How do I do

provided

dependencies with the Kotlin multiplatform plugin?

If I have a source-set that other source-sets depend on, it seems that source-set is assumed to be common. Is there a way to specify that a source set is a specific platform? If I don't specify the platform, then I lose the ability to import platform specific libs. To work around this currently I'm specifying an unused target.

Any idea yet how a multiplatform date+time library could look like? Like

java.time

? Or like Swift's? Or a mix of both? Java's seems to be focused on the Gregorian calendar while Swift's is more generic.

Is there a specific reason why the common

StringBuilder

is append-only? I.e. no replace/delete.

Hello does anyone have a sample code for sqldelight used in kotlin multiplatform using expect and actual for driver implementation pleaz?

uhhhhhh.... there is no iosX32 preset. i386 is required for iOS 10 support...

have anyone received this error trying to build a fat framework: Could not get unknown property 'FatFrameworkTask' for object of type org.jetbrains.kotlin.gradle.dsl.KotlinMultiplatformExtension?

This is a bit nuts 🤔

expect class Platform_TimeZone

// common

actual typealias Platform_TimeZone = ZoneId

// JVM - error because incompatible modality (ZoneId is abstract)

actual typealias Platform_TimeZone = NSTimeZone

// iOS - works fine If I make the expected class abstract, then it's the other way round 😞 Any way to work around that without wrapping everything in a new class?

Anyone have examples of a mpp framework that needs to dynamically link against another framework?

Is there an updated multiplatform plugin available for

1.3.40-eap-21

? Right now it doesn't seem like it (kotlin-eap repo)

Any ideas why

AtomicReference

is not available for me in common code? According to documentation is should be. Kotlin '1.3.30'

Is there an example or documentation somewhere that shows how to use JS DCE (dead code elimination) with the multiplatform setup?

What is the equivalent of the

compile

configuration for a java target in a multiplatform project? I used to have a way of including dependencies into a jar task, but since 1.3.31, it no longer works

Poked around Reaktive from Badoo. https://github.com/badoo/Reaktive. It seems to work OK, but can be quite unforgiving on the native side when things go wrong, and it really needs a set of extensions to avoid same-thread state capture freezing: https://twitter.com/kpgalligan/status/1130579650055417856 Testing was super limited, however. Not idea about general performance or anything else, but it’ll push you db updates to the screen.

Hi fellows! I’m struggling to make a multiplatform app in which the webApp should be made with Kotlin + React. So far I’ve been able to make it work with kotlin2js but I cannot even get the dependencies right to start writing juicy reactive code. Which dependencies should I use write Kotlin in a ReactJS fashion - or viceversa?

How to figure out what is being mutated [and causes an exception] during coroutine call, invoked from iOS code? The code is already as simple as that:

override fun fetch() {
        println("Fetch:start: Running in ${currentThreadName()} ")
        println("Fetch:start: Frozen? -> ${this.isFrozen()} ")
        launch(Dispatchers.Unconfined) {
            println("Fetch:launch: Running in ${currentThreadName()} ") 
         }
       }

Exception is in discussion thread ...

Why do I get

kotlin.native.concurrent.InvalidMutabilityException

[called from iOS] in the

init()

method by setting the

value

? During init() the object should not be frozen, right? (confirmed by println in code).

var value: Float
    init {
        println("MetricReference:init (${metric.name} ): Frozen? -> ${this.isFrozen()} ")
        this.metric = metric
        this.metric.addObserver(this)
        this.value = metric.getValue()
    }

I cant setup plugin plugin: ‘org.jetbrains.kotlin.xcode-compat’ with code:

kotlin { xcode {
        setupFramework('shared')
    } }

I got

Gradle DSL method not found: 'setupFramework()'

Could somebody help?

Hi, I'm trying to add a

common

module as a dependency to another

common

module but I'm not able to get it working. I tried with

implementation

,

api

and

compileOnly

but any of them give me a successful

build

. Could anyone helps me?

i see there's an

allJvm

. is there an

allIos

?

Hi! I'm trying to add a dependency to our MPP project and have everything public from that dependency exported as obj-c classes in that framework. we tried the

export

thing in

binaries.framework

, but that doesn't seem to work. Anyone else have success with this?

Does anyone have an example of including a subproject that's an mpp project into an mpp project?

Is there a Kotlin Multiplatform JSON library? I've read about Ktor and from what I understand it uses a different engine per platform, but it doesn't provide any common API so as soon as JSON handling happens it needs to be platform-specific?

The documentation states that iOS targets can only be built on a MacOS host. Would a Docker container work? Or does it have to actually be MacOS

we'd like to use something like mikrometer to implement some application monitoring. is there a way to put the needed annotations on my

common

code? Is there a different approach to achieve our goal? any suggestions? (i'd be completly fine with havong those metrics on my jvm-target only - i don't need them on the other platforms, if this helps)

Not sure where to ask for this but... In gradle (kts) can the

sourceSets

function's receiver be changed from

NamedDomainObjectContainer<KotlinSourceSet>

to

NamedDomainObjectContainerScope<KotlinSourceSet>

? (Or just delete the function altogether since the object is available) It allows for

"commonMain" { }

also, instead of just

val commonMain by getting { }

.

Hey guys, are function references available for K/N? I have functions like these ones:

//Declaration
fun <K,V>cache(getNew: suspend () -> List<Pair<K, V>>)
//Usage
cache(::getAllChannelsFromApi)

When compiling for Android everything works fine, but on iOS I get

Type mismatch: inferred type is KSuspendFunction0<List<Pair<Int, Channel>>> but suspend () -> List<Pair<Int, Channel>> was expected

What does plugin “xcode-compat” need for?
