hi, want to join ktor ios websockets development, how I can do it?

how to correctly call the function:

@kotlinx.cinterop.internal.CCall public external fun SCNetworkReachabilityGetFlags(target: platform.SystemConfiguration.SCNetworkReachabilityRef? /* = kotlinx.cinterop.CPointer<cnames.structs.__SCNetworkReachability>? */, flags: kotlinx.cinterop.CValuesRef<platform.SystemConfiguration.SCNetworkReachabilityFlagsVar /* = kotlinx.cinterop.UIntVarOf<kotlin.UInt> */>?): kotlin.Boolean { /* compiled code */ }

to receive the 

kSCNetworkReachabilityFlags…

 correctly? in Swift, we can make the call:

var flags: SCNetworkReachabilityFlags = []
if !SCNetworkReachabilityGetFlags(defaultRouteReachability, &flags) {
    return false
}

And receive the flags in an array style…. In Kotlin Native, I am doing:

// val flags = allocArray<SCNetworkReachabilityFlagsVar>(10) // -> this was my first attempt, they are 10 possible flags!
val flags = alloc<SCNetworkReachabilityFlagsVar>()

if (!SCNetworkReachabilityGetFlags(reachabilityRef, flags.ptr)) return false

the problem is I am receiving all the flag “summed” (they are 

kotlin.UInt

), and not split in an array, like in Swift.

Does anyone know of any examples of how to define cinterop settings to import a Swift xcframework?

StableRef

having object wrapping mutable property vs

AtomicRef

? Which is better to store a mutable object not-frozen (sort of for thread isolation)?

I don’t get it with the

IncorrectDereferenceException

It seems I cant use kotlin native on a background thread at all. (kotlin 1.4.21 and coroutines 1.4.2-native-mt)

import platform.darwin.DISPATCH_QUEUE_PRIORITY_DEFAULT
import platform.darwin.dispatch_async
import platform.darwin.dispatch_get_global_queue
import platform.posix.sleep
import kotlin.test.Test

class PersonGenerator

class MyTest {
  
  @Test
  fun test() {
    dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT.toLong(), 0)) {
      PersonGenerator()
    }
    sleep(1000)
  }
}

Uncaught Kotlin exception: kotlin.native.IncorrectDereferenceException: illegal attempt to access non-shared MyTest.$test$lambda-0$FUNCTION_REFERENCE$43@8ae08b08 from other thread

Just went through following to enable use of Swift

await

and

async

https://ohmyswift.com/blog/2020/12/25/experimenting-with-swift-async-and-await-pattern-using-xcode/ Are there any thoughts at this stage, for Kotlin/Native, how this could be mapped to Kotlin suspend functions?

hi, does anybody know how i can figure out the reason of endless

runDebugExecutableNative

process? google did not give me anything so far…

We are using kotlin-native to build a crossplatform library used on android and iOS. On iOS the the binaries for the different apple platforms are bundled in a xcframework and distributed inside a binary SPM-package. Everything works as expected when deploying locally but apple keeps rejecting our binary appstore with the following errors. Anyone has experienced the same and give us a hint how to fix this?

App Store Connect Operation Error

ERROR ITMS-90205: "Invalid Bundle. The bundle at '<http://XXXX.app/Frameworks/XXXXMobileShared.framework|XXXX.app/Frameworks/XXXXMobileShared.framework>' contains disallowed nested bundles."

Hi, I have a KMM project (android/ios) and I want to add a linuxX64 target to debug purpose (I'm not on mac and my ios colleauge has native problems). My project use sqldelight and it's not supports linuxX64. Is it a way to say to gradle to ingore the dependencie ? I don't need it for my debug.

Hi, if I would like to make sure that all targets (including tests) are compiled with the flag -copt (and not with -g) would adding thid be enough: binaries { all { optimized = true ; debuggable = false }}

Hi, Is there a way to call

ensureNeverFrozen

from common code or swift code ? For the moment I only can access concurrent functions like

freeze

and

ensureNeverFrozen

in the iosMain shared code. I have an

InvalidMutabilityException

calling ktor get function but I only call common code and can't use

ensureNeverFrozen

in commin code to debug

cinterop configuration (?) problem I think This commit broke my build https://github.com/bugsnag/bugsnag-cocoa/commit/82fee49fdeb0b46a9855e1fd8f2344f8c03fc0f4 It basically changes all imports from something like

#import "BugsnagApp.h"

to something like

#import <Bugsnag/BugsnagApp.h>

Error:

My def file:

depends = Foundation
package = framework.Bugsnag
language = Objective-C
headers = Bugsnag.h

compilerOpts = -framework Bugsnag
linkerOpts = -framework Bugsnag

Gradle cinterop configuration:

compilations.getByName("main").cinterops.create("Bugsnag") {
            defFile("src/iosMain/cinterop/Bugsnag.def")
            includeDirs.allHeaders("$projectDir/Carthage/Build/iOS/Bugsnag.framework/Headers")
        }

What can I do to make cinterop work with that commit’s change?

If I had a a kotlin library running in an AppleTV app, how would I debug the Kotlin code? The KMM plugin makes this easy for an iOS app, but I haven’t found any way to do this on apple tv yet.

Could this please get some love? https://youtrack.jetbrains.com/issue/KT-42098

Hi, why is

import kotlinx.cinterop.*

not available when used inside kotlin multiplatform (either commonMain or androidMain) ?

Any support (even experimental) for building Kotlin Native

macOS-arm64

frameworks (i.e. for Apple Silicon machines)?

I have an issue with

Undefined symbols for architecture x86_64

in a KMM project based on https://github.com/Kotlin/kmm-sample/blob/master/README.md. The ios framework (

:shared:linkDebugFrameworkIos

) only fails to link when disabling caching with

kotlin.native.cacheKind=none

(or if using Gradle composite builds for the dependencies), but works when using the cache when consuming the dependencies from a Maven repository. The unresolved symbols are defined as custom declarations in a cinterop-wrapper’s def-file and used by static libraries in the dependent module. The klibs passed to konanc seems right and the klibs seems to contain the right symbols in the

cstubs.bc

. The only difference on the konanc command line when it works (i.e. without

kotlin.native.cacheKind=none

) is a couple of additional

-Xcache-directory

entries, that indeed contains archives containing the symbols. I have tried getting details from the linking phase (by various `freeCompilerArgs`/ `linker-option`s) without luck. Any idea on how to get insight in the linker invocation through konanc or any known limitations/issues around linking against custom declarations in a module’s? The project is available at https://github.com/realm/realm-kotlin/tree/master/examples/kmm-sample

Is it possible to cast or convert a

NSNumber

Objective-C reference to a Kotlin

Number

? The docs describe casting the other way, but not clear how to accomplish the reverse.

does Kotlin Native overlap in some way with what Graal Native Image is trying to do? (compete newb here, just trying to get the lay of the land)

hey folks does anyone saw this kind of error? I'm getting this during building iOS framework. The error doesn't really tell much what causing it. Looking into https://github.com/JetBrains/kotlin-native/blob/7c3329e3e0c06be1e37fd4435bca7d39d88dfc8d/backend.native/compiler/ir/backend.native/src/org/jetbrains/kotlin/backend/konan/llvm/IrToBitcode.kt#L231 it's all stubs

class AppSession internal constructor(globalScope: GlobalScope) {

    private val appRepositoryFactory = globalScope.appRepositoryFactory

    init {
        CoroutineScope(Dispatchers.Default).launch {
            withContext(Dispatchers.Default) {
                appRepositoryFactory.profilesRepository
            }
        }
    }

this is not

class AppSession internal constructor(globalScope: GlobalScope) {

    init {
        CoroutineScope(Dispatchers.Default).launch {
            withContext(Dispatchers.Default) {
                globalScope.appRepositoryFactory.profilesRepository
            }
        }
    }

did someone had something weird? nothing is happening inside this “profilesRepository”. Without coroutines it also works. Error is:

Hi there, I am wondering. Is there a way to build an iOS framework with Kotlin and Swift mixed together? I am hoping to build a Kotlin core library/framework that I can share between my iOS and Android framework. But not sure how or even this is possible to work out. My preliminary research on the internet returned nothing much...

I’ve written macOS application by kotlin-native. If I install the application from standard path -

/Applications/myapp.app/Contents/MacOS/myapp.kexe

- I see blurred image (see the first image). If I move

/Applications/myapp.app

into home and run

~/myapp.app/Contents/MacOS/myapp.kexe

- I see the same. If I rename

~/myapp.app

to

~/myapp

and run

~/myapp/Contents/MacOS/myapp.kexe

- I see ok image (see the second image) What do I wrong? How can I fix it?

Where is KonanTarget located? Is KonanTarget a enum?

I noticed that when I expose a generic type from Kotlin Native to Swift, it's always nullable. E.g.

MyCoolGenericExample<T>

accessed from Swift will always have the

T

nullable. Is that true or am I missing something?

Is there something obviously wrong here that I'm missing? I always get

Unfinished workers detected, 1 workers leaked!

when running this code on linuxX64

hi all, question about crash/error reporting. How do i get the proper dsym files for the shared module? Added this to the gradle file of the shared module:

kotlin{
  targets.withType<KotlinNativeTarget> {
    binaries.all {
      freeCompilerArgs += "-Xadd-light-debug=enable"
    }
    binaries.withType<org.jetbrains.kotlin.gradle.plugin.mpp.Framework> {
      isStatic = true
    }
  }
}

I just hooked up my app to sentry and was testing things out, I see that I uploaded the dsym files, but everything's looking like this:

What's the current plans for being able to provide binary compatibility between versions of Kotlin.....I believe it's still case that for example with 1.4.30 release all libraries (that support kotlin/native ) will need to be updated?

How do you convert

ByteArray

to and from

CFDataRef

? I found this for converting to/from

NSData

, but having a hard time figuring out how to do something similar for

CFDataRef

. I need to create a

SecCertificateRef

, which I’m using

SecCertificateCreateWithData()

and

SecCertificateCopyData()

to create and get the data from.
