If I want to try out a dev build of K/N but my project relies on coroutines, is there a way to do it? I don’t see any coroutines builds that use 1.3.60 dev builds

Hi!! All Someone has coded location delegates in iosMain (the common part in Kotlin). I need to know if any type of delegates can be implemented in iosMain or the development must be in swift (because if that cannot be done, how scalable is KM?). Something like this https://discuss.kotlinlang.org/t/swift-delegate-cllocationmanagerdelegateprotocol/14320/5

Hi, https://kotlinlang.org/docs/reference/building-mpp-with-gradle.html#building-final-native-binaries I try to generate fat framework But import org.jetbrains.kotlin.gradle.tasks.FatFrameworkTask Can’t find FatFrameworkTask import Why?? Thanks

Hey, is there any suggestion for this? (Build Linux arm32 soft-float target) https://github.com/JetBrains/kotlin-native/issues/3350 I have no idea where to start, could you offer me some link, book or tutorial etc stuff for study it and implement it? Thanks a million.

TornadoFX is better or GTK with kotlin-native ?

Hi, Because of some reasons, I need to generate .so now, androidNativeArm64 -> arm64-v8a androidNativeArm32 -> armeabi-v7a if I really need armeabi (I know v7a support this set) What can i do Thanks

Hi, if I want to put task outside kotlin block how can I get “ios32” and “ios64" this two KotlinNativeTarget like XXX.targetName Thanks

Hi, seems reified type parameters don't work with the latest kotlin version 1.3.60-dev-2413. Tell me if I should create issue

inline fun <reified T> to(): T? = null

iOS ARM32 question: The constructor of

UIColor

expects `CGFloat`s (Float) on arm32 and `CGDouble`s (Double) on arm64 / x64. I'd like to use the same source set and unfortunately

.convert()

doesn't exist for Float / Double. Are different source sets the only way to tackle this?

I have an exception running cinterop on an Objective-C library. It is an NSEnum and I tried to specifically import the header file in the def file. What does the exception mean and how can I solve it?

Anyone else finding that upgrading to Xcode 11 breaks iOS tests in a multiplatform project?

Calling

freeze

on one of my objects resulted in

Memory.cpp:902: runtime assert: unknown node during condensation building

. Has anyone else experienced this issue or know the cause?

Hi, Does JVM platform can use cinterop ?? I got Error.

Does anyone have any experience with multithreading on macOS and getting around all the IllegalStateExceptions? I am seeing lots of random crashes but that seems somewhat expected because I am using

TransferMode.UNSAFE

which is meant to be used as a last resort

Would a Kotlin Native library (in KLib form) using Kotlin 1.3.41 be compatible with a Kotlin Native program using Kotlin 1.3.50?

Does anyone know how to add files from resources to the iOS simulator's bundle resources so that the files will be available during iosTests?

Do I understand correctly, that kotlin kode could be run either in UI thread or in BG thread on iOS? There is no way to have code work for UI and some doing heavy calculations (100+ seconds) for single particular app?

Is it possible to mutate a singleton instance from a background thread via

Worker.execute

with

TransferMode.SAFE

? Basically I want to keep a global cache as a singleton instance and have the background workers able to add things to the cache. But I think that may violate mutable XOR global.

Has anyone here found a good way to integrate a callback mechanism with the Workers API to do background execution? I want to kick off a background task and have it call a callback later without blocking, but that doesn’t seem to be possible if the callback mutates any state/references unfrozen objects. This seems like a fairly straightforward task but AFAIK there is currently no way to do it. I can do something like:

val input = ...
val callback: (Result) -> Void = ...
val future = Worker.start().execute(TransferMode.SAFE, { input.freeze() }) {
    // do work
    result    
}
val result = future.result
callback(result)

But obviously that blocks the calling thread until execution is finished. Open to other suggestions besides

Worker

but I am not aware of any other mechanism for multithreading since coroutines only run on main thread.

Is there something like JavaCPP for Kotlin/Native? i.e. a zero-configuration Gradle plugin or library which ships with prebuilt binaries for common libraries on common target architectures? What I'm thinking is something like this:

plugins {
      kotlin("multiplatform")
      id("org.kotlin.commonlibs")
}

commonLibs {
     compile("opencv2")
}

And it downloads the appropriate

klib

containing all the dependencies, which can be linked against the generated stubs and called from Kotlin/Native code without any further configuration. With JavaCPP this is dead simple, you just add the Maven coordinates and can immediately call native libraries (bundled in the JAR) on any target architecture. https://github.com/bytedeco/javacpp-presets

Just saw the draft K/N changelog for 1.3.60. I thought new -Xg0 flag was 1.3.50? Anyone or JB folks know?

Why? Did I do something wrong?

What is recommended way to have mutable object structure that work in iOS? Mutable only from kotlin code. Structure have thousands-to-millions of objects.

I'm getting this when trying to link WASM to release executable:

error while loading shared libraries: libtinfo.so.5: cannot open shared object file: No such file or directory

Any tips?

Are there any plans to add something like this to kotlin/WASM? https://rustwasm.github.io/docs/wasm-bindgen/examples/dom.html Currently there're only jsinterop hooks for canvas

Is anyone running a fully native Kotlin server yet? If so then where and what's the experience (performance, stability, ease of development & deployment)?

Multi-threading in a Kotlin MPP project is quite difficult due to the limitations that the K/N Worker API sets in place 😞
