Trying to free a msg via the MQTTClient_freeMessage function however it doesn't accept a CPointer<MQTTClient_message>?. The function only accepts a CValuesRef<CPointerVar<MQTTClient_message>>?. Below is the mapping for MQTTClient_message:

@kotlinx.cinterop.internal.CStruct public final class MQTTClient_message public constructor(rawPtr: kotlinx.cinterop.NativePtr /* = kotlin.native.internal.NativePtr */) : kotlinx.cinterop.CStructVar {
    public companion object : kotlinx.cinterop.CStructVar.Type {
    }

    public final var dup: <http://kotlin.Int|kotlin.Int> /* compiled code */

    public final var msgid: <http://kotlin.Int|kotlin.Int> /* compiled code */

    public final var payload: kotlinx.cinterop.COpaquePointer? /* = kotlinx.cinterop.CPointer<out kotlinx.cinterop.CPointed>? */ /* compiled code */

    public final var payloadlen: <http://kotlin.Int|kotlin.Int> /* compiled code */

    public final val properties: paho_mqtt.MQTTProperties /* compiled code */

    public final var qos: <http://kotlin.Int|kotlin.Int> /* compiled code */

    public final var retained: <http://kotlin.Int|kotlin.Int> /* compiled code */

    public final val struct_id: kotlinx.cinterop.CArrayPointer<kotlinx.cinterop.ByteVar /* = kotlinx.cinterop.ByteVarOf<kotlin.Byte> */> /* = kotlinx.cinterop.CPointer<kotlinx.cinterop.ByteVarOf<kotlin.Byte>> */ /* compiled code */

    public final var struct_version: <http://kotlin.Int|kotlin.Int> /* compiled code */

Hello, I am working on an open source project, which is a client relying on

ktor

. I am trying to add an ios target, and run into this exception when trying to build. You can reproduce for yourself by checking out the

feature/ios

branch of https://github.com/algolia/algoliasearch-client-kotlin

I’m trying to run my test with Xcode generating a test framework. I’m using cocoapods. Is the configuration below correct? I can’t find any framework with name test in my build folder 😞

kotlin {
    targets {
        final def iOSTarget = System.getenv('SDK_NAME')?.startsWith("iphoneos") ? presets.iosArm64 : presets.iosX64

        fromPreset(iOSTarget, 'ios') {
            binaries {
                framework('client')
                framework('test') {
                    compilation = compilations.test
                    linkerOpts += ['-framework', 'UIKit']
                }
            }
        }
    }
    cocoapods {
        // Configure fields required by CocoaPods.
        summary = "chat-client"
        homepage = "<https://github.com/felipehjcosta>"

        pod('SocketRocket', '0.5.1')
        pod('OHHTTPStubs')
    }
}

Is it possible to disable GC in Kotlin/Native for iOS? We see for instance when referencing ARFrames huge lags, as K/N retains instances and a GC cycles is roughly 30secs away. We can mitigate it only with a forceGC after every delegate callback.

Hello, I am working on a mac but do I need to be on a mac to compile Kotlin/Native for iOS or does it work on a linux machine as well?

On my project I'm depending on the artifacts produced by another Kotlin Multiplatform library - it also produces native artifacts etc (in this case the ones for iOS):

val commonMain by getting {
    dependencies {
       //....
       api("dependency-group:dependency:version")
    }
}

When I'm trying to run the

linkDebugTestIosX64

gradle task I'm getting this error:

e: Compilation failed: Cyclic dependency in library graph for: /Users/boni/Documents/Programmieren/Kotlin/StihlBusiness/StihlBusiness/build/classes/kotlin/iosX64/main/Library

 * Source files: StoreTest2.kt
 * Compiler version info: Konan: 1.3.1 / Kotlin: 1.3.40
 * Output kind: PROGRAM

Is there a way to debug this to get better information?

I am unable to get a really basic selector working in iOS - here's what I'm doing.

class ClosureSleeve(val closure: () -> Unit) : NSObject() {

    @ObjCAction
    fun runContainedClosure() {
        closure()
    }

    val selector: COpaquePointer? get() = Companion.selector

    @ThreadLocal
    companion object {
        var selector: COpaquePointer? = sel_registerName("runContainedClosure")

        fun printMethods(){
            val instance = ClosureSleeve{}
            val type = object_getClass(instance)

            println("Now there are implementations:")
            memScoped {
                val sizeOutput = this.alloc<UIntVar>()
                println("My class: ${type}")
                val mlist = class_copyMethodList(type, sizeOutput.ptr)
                if(mlist == null){
                    println("Failed to pull selectors, null response.")
                    return@memScoped
                }
                val size = sizeOutput.value.toInt()
                println("Selector size: $size")
                for (i in 0 until size) {
                    println("Method $i: ${sel_getName(method_getName(mlist[i]))?.toKString()}")
                }
            }
            println("Attempted registry: $selector")
            println("End selectors.")
        }
    }
}

I'm then using it from Swift to keep that section isolated:

let sleeve = ClosureSleeveKt.makeSleeve {
            print("Test")
        }
        print("Sleeve: \(sleeve)")
        self.sleeve = sleeve //Not to worry; strong ref here
        button.addTarget(sleeve, action: NSSelectorFromString("runContainedClosure"), for: .touchUpInside)

When it prints out what methods are available,

runContainedClosure

is not there, just

init

and

dealloc

. Can anybody help? I've been working on this for several days and been unable to get it to work. I see that @spierce7 successfully got something like it working at one point.

I created a multiplatform HTML streaming library. For fun I thought I'd benchmark it for macosX64 and JVM. Here is a link to the benchmark: https://github.com/ScottPierce/kotlin-html/blob/master/benchmark/src/commonMain/kotlin/dev/scottpierce/html/benchmark/SimpleBenchmark.kt Results:

JVM: Benchmark Completed. Benchmark Total Millis: 17324, Average iteration was 346.42 millis
Native: Benchmark Completed. Benchmark Total Millis: 185398, Average iteration was 3707.94 millis

Is it possible to use WKWebView on macOSX target for kotlin native? I do not seem to find any imports for it? (https://developer.apple.com/documentation/webkit/wkwebview)

Is there any ideas or maybe guide how to use self-compiled kotlin-native? We want try to use some features from master (but it's not available in 1.3.40) I've compiled kotlin native from this build (by guide from KN's Readme) https://github.com/JetBrains/kotlin-native/releases/tag/build-1.3.50-dev-2041 and now I have klib.jar Does anybody have an idea how to use it instead of the release version?

With relaxed mode, does that also mean that we'll get some Lock / synchronization utils?

Hello, is it possible to use in kotlin addObserver on NSObject? I want to observe the property value of native object without success. I also tried to implement my own NSObject using this swift example as reference https://developer.apple.com/documentation/swift/cocoa_design_patterns/using_key-value_observing_in_swift. Is anyone have more success and want to share with me?

Are there plans for a Kotlin Package Manager ? similar to SPM and Crates, something focused on simplicity, accessibility and extensible, written in native language to avoid slowness and flaws of gradle

Noticed that documentation (KDoc) and source code (Kotlin source files) aren't available when using a Kotlin Native library (a KLib written in Kotlin) via Gradle. Will that be fixed in a newer version of the Kotlin plugin? This is the Kotlin Native library I'm referring to for reference purposes: https://gitlab.com/napperley/kmqtt-client

I would like to use a finalize hook in iOS NSObject. How can I implement

dealloc

in Kotlin? I will as a final step call super.dealloc to dispose KRefSharedHolder, but before that I would like to clean-up scoped pointers

I'm trying to share a test library with my iOS team. They are telling me that I need to have the framework compile to

arm64 arm64e armv7 armv7s

. Can kotlin/native do arm64e or armv7s?

I was having trouble accessing the companion object instance from Swift code. We could access it, but had to create an instance of the companion object to do so, i.e.

<Kotlin Class>.Companion().<companion function>()

. Did we overlook something, or is this a known limitation?

So my iOS team needs me to provide them a framework, but that framework needs to support several different kotlin/native platforms, while being compiled to a single framework. Are there any examples of doing this, or would anyone know how?

I know that developers usually don't like to read standalone docs, but this one is surprisingly good, especially in native part: https://kotlinlang.org/docs/reference/building-mpp-with-gradle.html

Is there a Kotlin Native sample that shows how to wrap a C Macro to create new instances (like a Struct for example) and manually free them later on?

Having some issues with the cocoapods integration. Anybody know where that plugin is kept, and best place to file bugs? I’m pretty sure it’s in the “main” kotlin repo and not native, but having some trouble tracking it down and want to make sure it’s not in a special place.

Hy guys. I noticed that compiler just ignore

suspend

methods and doesn’t warn about that due compilation for iOS. So, is it possible to enable such warnings?

What are the top priorities for Kotlin Native (apart from iOS support)? WASM support has been mentioned as not being a top priority ( https://kotlinlang.slack.com/archives/CDFP59223/p1563365970024200?thread_ts=1563324949.014100&amp;cid=CDFP59223 ).

Hello i have 2 questions one about compilation and another about tests : 1) when your shared code is compiled with kotlin native for android does it use jvm or other thing? 2) I tried mockk to unit test my shared code but i saw recently that when you launch it through android studio it use jvm so i'm wondering what is the good way to test shared code for ios and android?

Is coroutines supported in Kotlin/Native or CommonMain modules?

Anybody else tired of all the Int <-> Int32 casting in swift with MP library? Anybody find a clean way around this?

Hey there, I have a question about performance, how big is overhead when it's comes to only calling method from C?

What features from Kotlin/JVM aren't available in Kotlin/Native?
