has anyone figured out a way to make resource files available when running iOS tests (on the sim)?

Hello, I read it will be possible to use Jetpack Compose outside of android (community effort though), and I was wondering if it would be possible to do so with any other jetpack library (room, livedata, for instance)

is there anything similar to

BuildConfig

for Android? I haven't seen anything.

it looks like expect/actual are not resolved properly by IDEA for

commonTest

, even though they are for

commonMain

. it doesn't handle source set dependencies properly.

Hi all, I wonder if anyone has hands-on experience with

Flow

in MPP/KN modules? Got any tips & tricks? I'm trying to expose shared repository layer for iOS/Android, and considering which

Observable

implementation to expose. Would really like to avoid

Reaktive

, having already coroutines and RxJava in the project... Thanks in advance!

Good morning, folks! Now and then, when including a new library in my MP project, I get an

unresolved reference

error when trying to import the dependencies. Android Studio says everything is fine, and I can even inspect the source by cmd+clicking, but when building the project the errors starts appearing. Now it’s Kissme I’m trying to import. I’ve put the

implementation

in all source sets (including test, just in case) with the corresponding suffix. I don’t know what else to do. Any suggestions?

I’m trying to create a custom iOS

UIView

and override this function: https://developer.apple.com/documentation/uikit/uiview/1622529-draw but I don’t see it in Kotlin, what may be the reason?

Is there a way to obtain platformName in code without manually declaring

expect val platform:String

?

Happy New Year! After updating Kotlin to 1.3.61, I have the a problem with iOS. I get

unresolved reference: platform

on Android Studio in my

iosMain

files, unless I add this:

iosX64Main {
    …
    kotlin.srcDirs += project.file("src/iosMain/kotlin")
}
iosArm64Main {
    …
    kotlin.srcDirs += project.file("src/iosMain/kotlin")
}

(I can generate the library though, so it seems the problem is with Android Studio) But if I add that, then it starts expecting new actuals:

expected class 'X' has no actual declaration in module my-app_iosX64Main for Native

what do i need to change this to?

Hey folks, I'm struggeling a bit with kotlin mutliplatform and

commonTest

. In my

build.gradle

i have the following config:

kotlin {
  ... 
  sourceSets {
     ...
       commonTest {
            dependencies {
                implementation 'org.jetbrains.kotlin:kotlin-test-common'
                implementation 'org.jetbrains.kotlin:kotlin-test-annotations-common'
            }
        }
   }
}

However, if I run a test in

src/commonTest/kotlin/my/package/FooTest.kt

which looks like this

import kotlin.test.Test
import kotlin.test.assertEquals

class FooTest {
    @Test
    fun filterState(){
        assertEquals(1, 2)
    }
}

I get

Unresolved reference: Test

e: ... /src/commonTest/kotlin/my/package/FooTest.kt: (3, 20): Unresolved reference: Test

e: ... /src/commonTest/kotlin/my/package/FooTest.kt: (4, 20): Unresolved reference: assertEquals

Any idea what I have misconfigured?

Hey guys, I observed for at least 6 month a strange behavior which I cannot fix. When I compile my mpp project from the cli it works fine, as expected. When I run the same gradle task from intellij I get tons of "Actual class foo has not corespondending expected declaration". If someone has some time to check it here is my repo: https://github.com/rewe-digital-incubator/Konversation/tree/feature/provisioning (that feature branch should have also all the latest versions of the dependencies) tbh I didn't care yet for this bug since I was able to compile my project, but this breaks debugging and running tests which is very annoying

What should I set

core.symlinks

to for my project if I have symbolic linked iosX86 and iosArm to a common directory? I assume I want

false

to maintain compatibility with Windows collaborators?

Just trying out appcode for the first time and it is cool that it generates a .swift version of the generated objectivec. When I rebuild the framework this .swift file does not get regenerated. Is there anything I can do to regenerate the .swift file. I discovered it by cmd+b'ing into the generated objc classes.

Hi guys! Is there something like a

WeakReference

in Kotlin MPP? I have a custom

EventBus

implementation which returns

Subscription

objects whenever the user subscribes to an event. My problem is that it is easy to forget to call

Subscription.unsubscribe

and there can be memory leaks when the subscriber drops the reference to the

Subscription

but the

EventBus

retains it forever. Is there a best practice for this scenario in the context of MPP?

One selling point for winning over product managers on multiplatform is a far higher probability of consistent analytic events cross platform. Imagine a ViewController/Activity that has a

fun render(state: ViewState)

and observes

ViewState

's emitted by a StateMachine. The StateMachine is shared in the common module. If the analytics events are fired in the StateMachine, then the developer who implements the View would have to avoid using the shared StateMachine or use it in a way that breaks functionality in order to make analytics events inconsistent, which is a loose coupling and better than no coupling.

Has anyone tried out getting a websocket working on iOS? Seems like ktor does not support it directly, but one could use their

Engine

API to bake Starscream or any other third party library into it

Hi guys, our company uses bitbucket. Is it possible to upload a library from bitbucket to jitpack? I've heard that bitbucket doesn't support

release

features like the ones on github.

I am surprised I had not noticed this before, but I needed a String.format in common code (%.2d for example), and turns out it is only on JVM. Seems like some low hanging fruit. 🙂 Maybe for 1.4?

How can I create a commonNative sourceSet (or better yet, target) with access to native stdlib and depend on it from linux and mingw targets?

has anyone setup an MPP to build a fat jar? or configured the java/shadow plugins?

Hello, is there a preferred way to do url encoding on KMP? kTor seems to be the only option I've found so far

Hi guys, I have a multimodule multiplatform project which is imported into plain android project.The project can see it's interfaces and transitive dependecies, but cannot resolve the interface's return types which are from the transitive dependencies. The dependencies are declared as api(...) in the imported module. Is there anyone, who faced similar issues?

Hello Guys, I want to build my KMPP iOS sources into an iOS static library, and my iOS kotlin code uses some ObjC classes from another iOS framework, which are accessed using cinterop. When my ObjC app code (

ViewController.m

) calls iOS kotlin function (

KmppBootstrap.test

, built to iOS static library), which accept an ObjC object (

IOSDummyObj

from

IOSDummyFramework.framework

), if

KmppBootstrap.test

use

IOSDummyObj

, my app will crash at

Kotlin_Interop_refToObjC

with

EXC_BAD_ACCESS (code=1, address=0x1a102ba0120)

, but if

KmppBootstrap.test

don't, my app runs fine. Could you guys please help me, thanks! I upload my repro project onto GitHub, in the

ios_static_lib_repro

branch of https://github.com/Piasy/KmppBootstrap , my iOS kotlin code is mainly

kmpp/src/iosMain/kotlin/com/piasy/kmpp/KmppBootstrap.kt

, and iOS app is under

iOSExample2/iOSExample2/ViewController.m

. Or maybe my app code is wrong?

IOSDummyObj* obj = [[IOSDummyObj alloc] initWithInt:42];

    libkmpp_ExportedSymbols* lib = libkmpp_symbols();

    libkmpp_kref_com_piasy_kmpp_KmppBootstrap kmpp = lib-><http://kotlin.root.com|kotlin.root.com>.piasy.kmpp.KmppBootstrap.KmppBootstrap();

    libkmpp_kref_Dummy_IOSDummyObj dummy;
    dummy.pinned = (__bridge libkmpp_KNativePtr)(obj);
    lib-><http://kotlin.root.com|kotlin.root.com>.piasy.kmpp.KmppBootstrap.test(kmpp, dummy);

Anyone who would have a simple example (or link to it) of a React Native app calling a Kotlin Multiplatform library? Looking on the web for it, but haven't found exactly what I'm looking for yet. (NOTE: I'm just starting with React Native, I don't have any experience.) EDIT: I have 2 libraries (.jar for Android, .framework for iOS).

Using ktor on iOS with

io.ktor:ktor-client-core-native

and I’m getting this:

CredStore - performQuery - Error copying matching creds.  Error=-25300, query={
    class = inet;
    "m_Limit" = "m_LimitAll";
    ptcl = htps;
    "r_Attributes" = 1;
    sdmn = "oauth2/client";
    srvr = "<http://myserver.app|myserver.app>";
    sync = syna;
}

Does anyone know what could be the issue?

I have a project with following structure:

common
  - commonMain (contains expect classes)
  - jvmMain (contains actual classes for jvm)
  - jsMain (contains actual classes for js)
jvm (contains a jvm project and depends on common)
 - JVMMainClass
js (contains a js project and depends on common)
 - JSMainClass

the jvm works fine but I have a problem with js module.

JSMainClass

sees classes from common module but the implementations are from jvmMain instead of jsMain. How do I fix that?

How would I specify a different name for

commonMain

in a mpp gradle file?

Trying to get a set up that looks like this:

jvmCore
  |_ main
       |_ kotlin
  |_ test
       |_ kotlin

instead of

jvmCoreMain
  |_ kotlin
jvmCoreTest
  |_ kotlin

But can't quite figure out how to configure my sourceSets properly. I have it set up like this:

sourceSets {
    jvm().compilations {
        val core by creating {
            defaultSourceSet {
                dependencies { //etc }
            }
        }
        val coreTest by creating {
            defaultSourceSet {
                dependencies { //etc }
            }
        }
    }
}

Is it possible to set it up more like..

sourceSets {
    jvm().compilations {
        val core by creating {
            sourceSet("main") {
                dependencies {}
            }
            sourceSet("test") {
                dependencies {}
            }
        }
    }
}

?
