Does anyone know if it’s possible to access

kotlin.system.getTimeMillis

from a custom source directory? I have a shared

nativeMain

module, on which all my native modules depend. I couldn’t find any

std

native lib I could depend on

When building a K/N library, do all varieties of Kotlin classes (i.e. data class/class/etc.) all get compiled into plain old obj-c classes? I ask because I am currently using a data class to represent a graph that stores a large amount of data (including nested data classes of various types), and performance on the macOS side - even just accessing instances of that class - becomes extremely slow as the number of nodes stored in an instance grows.

hi all! we at IceRock release new gradle plugin for KMM - MOKO KSwift. With this plugin you can generate Swift-friendly API for Kotlin/Native framework. See examples in readme, in sample project and also you can read post on medium. Also you can extend logic of plugin inside your project - implement own generators of Swift code. Feel free to give feedback - here in thread or on github issues.

Hi Everyone, after using kotlin "org.jetbrains.kotlin:kotlin-gradle-plugin:1.5.20" i am facing issue while generating jacoco report Error i am getting

at org.gradle.api.internal.tasks.execution.ExecuteActionsTaskExecuter.lambda$executeIfValid$1(ExecuteActionsTaskExecuter.java:187)

at org.gradle.internal.Try$Failure.ifSuccessfulOrElse(Try.java:268) if downgrade the version to 1.4.21 then it's working fine

are there any example projects running c++ code using kotlin/native as a shared lib?

There is a situation where I am stuck. With the libssh library I am trying to use the sftp_open function ( https://api.libssh.org/master/group__libssh__sftp.html#gaad64845af1100fb9325f20812f38da3b ), however the last function parameter (mode) seems to be expecting an octal literal (not entirely sure) which Kotlin doesn't support. Also the last function parameter involves doing a bit of bit banging (eg

mode & ~umask

). It isn't clear how to do this with Kotlin since it doesn't provide any bit manipulation operators. Below is the binding for the function:

@kotlinx.cinterop.internal.CCall public external fun sftp_open(session: libssh.sftp_session? /* = kotlinx.cinterop.CPointer<libssh.sftp_session_struct>? */, @kotlinx.cinterop.internal.CCall.CString file: kotlin.String?, accesstype: <http://kotlin.Int|kotlin.Int>, mode: libssh.mode_t /* = kotlin.UInt */): libssh.sftp_file? /* = kotlinx.cinterop.CPointer<libssh.sftp_file_struct>? */ { /* compiled code */ }

Is it expected that

freeze()

does not freeze items inside a collection?

Hey folks, quick question, is it expected that when I have this sealed hiearchy:

sealed class Parent {
    object Child1: Parent()
    object Child2: Parent()
}

I still get

Parent.init

available in Objective-C/Swift, even though this class cannot be instantiated in Kotlin. Should I file a bug?

How do I check if the file exists by its relative path? e.g.

existingDir/nonExistingDir/../existingFile

always return false with both, access ans stat

Hey people - another day another question - I am currently try to hook in a dynamic Library from Swift into Kotlin...the Definition this far is fine...but the linker is not able to find the actual framework and after crawling for an answer...I did not find any good pointers...so I'd like to ask if anybody has some hints/advises/tutorials for hooking in a dynamic library (explicitly not static) into Kotlin for iOS?

So I updated IntelliJ IDEA and now I have lost completion and everything about my cinterops in IDEA. Anyone knows how to reliably get them back? I tried resetting everything and rebuilding a few times

Is there any workaround to avoid

@Throws

annotation and handle the error on the native platform side. For example I have function in kotlin native that can throw

SocketTimeoutException

, Is there anyway to handle it on the iOS side without adding the

@Throws

annotation on my function?

Hi! Is there a way to unsafely cast

ULong

to

Double

other than read/write it to

ByteArray

?

Is there any way to get backtrace on linux(linuxX64, linuxArm64....), wasm and mingw? For example, * Darwin

NSThread.callStackSymbols

* JVM

Thread.currentThread().stackTrace

Where should we store PNG assets to access them from kotlin native ios?

I need to make a very simple http server in a kotlin native app (just for rpc with a webapp). I can't find any kotlin-native-ready http server libraries, so does anybody know of any, and if not, what would be the best choice for making a simple tcp listener in kotlin native (and I could slap together a simple http implementation that would be good enough for my purposes)?

is anyone aware of any plans for the concepts of project loom (mainly virtual threads with fibers) to be implemented in kotlin native? i am aware that it is not a simple copy paste operation and would be a big project to re-implement it, but the effective benefit of virtual threads is massive, so imo, it is certainly worth implementing

I am having an issue building my cinterop library, below is the cinterop file I produced to bind

glib

. While it produces the bindings, When attempting to build I get the following error

Hi guys, has anyone ever encountered this error: ? including GitLiveApp/firebase-kotlin-sdk messed up my unit testing on iOS 😞

does anyone can import the

kotlinx.coroutines.newSingleThreadContext

on kotlin native source folder?

Are there any functions like finalize/dealloc in K/N Object？I have a CInterop delegate class like that.And When it's gone,I need to free the delegate pointer.

class AssetExp {
    val delegate: CPointer<AssetModel>?

    constructor(){
        delegate = makeAssetModel()
    }

    //when Kotlin Object gone, call this functions
    fun finalize(){
        releaseVideoAssetModel(delegate)
    }
}

I have create a class which is a subclass of NSNumber and I export it to Kotlin. When I invoke that object method , I found the type in runtime is changed to a class which is auto generated by kotlin multiplatform instead of my class. But if I let that class inherit from NSObject, everything will be all right. I wonder to know, what happened when I made it inherit from NSNumber.

What might that mean?

My app crashes with this error when something like this is invoked from swift code

libraryManager.observeDownloadErrors()

. What is also funny here, is that usually when I try to navigate to a kotlin method in xcode, it takes me to the shared.h file which is barely legible obj-c gibberish. But when I navigate from this particular method which crashes, it takes me to some Swift file (but is still definitely what I have defined in kotlin):

public class LibraryManager : KotlinBase {
    open func observeDownloadErrors() -> KoruFlowWrapper<SomeKotlinException>
    ...
}

my ios tests stopped working with

* Compiler version info: Konan: 1.5.21 / Kotlin: 1.5.21

It's similar to this, but somehow it builds just fine for the ios app but fails for tests. Changing JDK didn't work either. I can;t go with 1.5.30-M1 yet (as per this comment)

Hi guys! I am wondering if K/N list implementation differ in any level from Kotlin Common. For instance:

val mutableList = mutableListOf<Int>()
    val immutableList = mutableList.toList()

Wondering if K/N handle

toList

method in some different manner? Does it use

copy

operation or simply check the type and cast as it does in stdlib?

Has anyone managed to successfully use K/N with the Xcode 13? I’m getting Cinterop error on 1.5.30:

/Applications/Xcode-beta.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator15.0.sdk/System/Library/Frameworks/Foundation.framework/Headers/NSURLSession.h:500:168: error: expected ')'

I’m having trouble building ios apps from commandline via xcodebuild when they import Kotlin code via the auto-generated embedAndSignAppleFrameworkForXcode task. Building from Xcode itself works fine, but if I do a command like this

xcodebuild -sdk iphoneos -configuration Debug -workspace ./sample/app-ios/SettingsDemo.xcodeproj/project.xcworkspace -scheme SettingsDemo build

then I get this error when hits that gradle task in the script phase

A problem was found with the configuration of task ':shared:embedAndSignSharedAppleFrameworkForXcode' (type 'Copy').
  - Type 'Copy' property 'sign' doesn't have a configured value.
    
    Reason: This property isn't marked as optional and no value has been configured.
    
    Possible solutions:
      1. Assign a value to 'sign'.
      2. Mark property 'sign' as optional.
    
    Please refer to <https://docs.gradle.org/7.0/userguide/validation_problems.html#value_not_set> for more details about this problem.

Does anyone have insight on what’s going wrong, or what else I can pass to xcodebuild to better mimic what’s happening when I build from the Xcode UI?

How to compile K/N program with static linking? I not need link with local libc. I can compile as static library, then compile with C stub and use ld options for static build, but may be there's a more convenient way?

I'm considering using Kotlin native to make an executable that wraps a C library and allows interfacing with it. Is there any reason that I should be wary of using Kotlin Native for this? I need to make executables that run on Mac and windows On x86 and arm.
