So Kotlin native does not have yet a package dependency tool.. right?

something like npm, maven, apt...

Getting stuck with translating a C Macro (creates a Struct? - https://www.eclipse.org/paho/files/mqttdoc/MQTTClient/html/_m_q_t_t_client_8h.html#aefd7c865f2641c8155b763fdf3061c25) into a custom def declaration (https://github.com/JetBrains/kotlin-native/blob/master/INTEROP.md#adding-custom-declarations) that will create a instance of MQTTClient_connectOptions (generated class in the KLib). This is part of a Kotlin Native program which uses the Eclipse Paho MQTT Client library (https://www.eclipse.org/paho/clients/c/).

For using Kotlin Native in iOS do I need to learn c++? or Just Kotlin and Swift? especially if I want to develop a cross platform libraries in Kotlin Native like KNArch.db

Hi! I'm try using konanc in linux inside corporate network without any possibility of internet access. Can I install all dependencies manually, without "Downloading native dependencies (LLVM, sysroot etc). This is a one-time action performed only on the first run of the compiler."?

Hi! I am using Kotlin/Native to develop multiplatform projects including iOS through appcode. I was wondering how do you use storyboard to have connection outlets to Kotlin files? With XCode and Swift, we can just use control+drag thingy. But, XCode does not do that for Kotlin files. Yet, the default project by appcode for Kotlin/Native for iOS already has outlet connections to Kotlin files. I was wondering how could we add more objects and have outlets for them too. Of course, not using storyboard is an option but that sample project actually does use storyboard!

Is there a way to wrap a CVariable into a CValuesRef?

I wonder what is the advantage of using Kotlin native over React Native ?

What is the difference between kotlinc and konanc?

@olonho Is there anything different of the performance characteristics with the kotlin/native reference counting implementation than other languages like Swift or Rust?

Hi! I am using Kotlin/Native to develop multiplatform project and was wondering how should I structure the project and which IDE to use? Like should we have android, ios, js etc. as separate modules in the same project? Or should we have a separate project for ios and separate for say common+android+js with each as modules. And then we could use Gradle to link this project with iOS. Also, how would this playout with the IDE for each project?

I wonder what this mean Android's switch to LLVM/Clang as the default platform compiler in Android 7.0 is Android already using LLVM like ios?not JVM https://android-developers.googleblog.com/2018/06/compiler-based-security-mitigations-in.html

To use Audio Toolbox on iOS via Kotlin Native, I have the following code: var url = NSBundle.mainBundle.URLForResource(file, "mp3") var id:Int = 0 val status = AudioServicesCreateSystemSoundID(url, cValuesOf(id)) AudioServicesPlaySystemSound(id) However, the url should be CFURLRef for AudioServices instead of NSURL returned by the URLForResource method. I tried bridging using: var cfurl = CFBridgingRetain(url) as CFURLRef val status = AudioServicesCreateSystemSoundID(cfurl, cValuesOf(id)) But, that throws a class cast. Not casting as CFURLRef results in a compiler error. Appreciate any pointers on what to try.

Kotlin Native works on the Raspberry Pi 2 (via cross compilation). Is the latest Raspberry Pi (3 Model B+ - https://www.raspberrypi.org/blog/raspberry-pi-3-model-bplus-sale-now-35/) supported as a target?

I just wandering if K/N has plan to support armv7/7s for iphone or not.

Hi, I have started exploring kotlin native and the integration with iOS, here the repository with all the information I'm collecting. Advices and pull requests are welcome. Enjoy 😁 https://github.com/defio/KotlinNativeExperiments

Hi! How the best way to produce object file (somelib.o)? I trying this way:

kotlinc -opt ./file.kt -o file -produce bitcode
llc -filetype=obj file.bc -o file.o

But it does not include standard library and result of

cc

compilation is:

/usr/bin/ld: file.o: relocation R_X86_64_32 against undefined symbol `ktype:kotlin.text.StringBuilder' can not be used when making a shared object; recompile with -fPIC

In the default Kotlin/native AppCode application demo, I see the following code snippet:

@ObjCAction
    fun buttonPressed() {
        label.text = "Konan says: 'Hello, ${textField.text}!'"
    }

It's not clear how the

@ObjCAction

is routing to the button that's being pressed. It's also not clear how that button is being selected. Can anyone point me in the right direction?

I'm trying to set a click listener programmatically in an iOS application, and I'm getting an error because I'm setting the bridge incorrectly. What should the value be for the bridge?

@ExportObjCClass
class ViewController : UIViewController {
    constructor(aDecoder: NSCoder) : super(aDecoder)
    override fun initWithCoder(aDecoder: NSCoder) = initBy(ViewController(aDecoder))

    @ObjCOutlet lateinit var label: UILabel

    @ObjCOutlet lateinit var textField: UITextField

    @ObjCOutlet lateinit var button: UIButton

    override fun viewDidLoad() {
        super.viewDidLoad()

        button.addTarget(this, action=sel_registerName("buttonPressed"), forControlEvents=UIControlEventTouchDown)
    }

    @ObjCMethod(selector = "buttonPressed", bridge = "ViewController") fun buttonPressed() {
        label.text = "Konan says: '2, ${textField.text}!'"
    }
}

I'm currently using

initBy(ViewController(aDecoder))

, but

initBy

is deprecated. The message tells me I can replace

initBy

with

@OverrideInit

on the constructor, but every time I do, I get an error:

constructor with @OverrideInit doesn't override any super class constructor.

Is there an example somewhere of how to use this annotation properly? It seems no matter what I do it doesn't work.

Hey guys, our team is currently developing an image processing engine in Kotlin that is used in our Android and in the future also in the iOS app. Currently, its’ an Android library running on the JVM but we need to find a solution to share the code base with iOS (no Android specific code involved). We see these most favourable options: 1. Using Kotlin Native 🚀 2. Using Swift and accessing it via JNI Wrapper on Android (we need to rewrite our Kotlin code to Swift code) 3. Using C++ (which most developers are not familiar with, so option 1 & 2 are definitely our favourites) The problem: K/N is not stable right now and we are worrying how much support it will receive in the future. K/N also never has been used in any production App (apart from Jetbrain’s Conf App). My Questions: 1. Any news on a release date for a stable version of K/N? 2. Do you know any specific company which is using K/N in production? My best guess right now is, that we rather go with Swift or C++ since we can hardly base our future development on sth non-stable 💔 😕 but we would really love to if we know that K/N receives serious amount of development in the next time ❤️ 💃 It’s a big project, so we need to be considerate with our choice of technology. I did a lot of research and I only saw this rather unspecific statement of olonho: https://github.com/JetBrains/kotlin-native/issues/1166

I have never worked with anything "native" before, only JVM, so I don't know what's possible with K/N. I am wondering: can I interact with an HID device via K/N, or is that is totally out of scope? https://docs.microsoft.com/en-us/windows-hardware/drivers/hid/introduction-to-hid-concepts

I noticed recently that Kotlin extensions are no longer exposed to ObjC/Swift as extensions, but instead as classmethods on a somewhat unusually named class... I'm pretty sure that they actually appeared as extensions using an earlier build though. What is the reason for the change? Will be extensions be returning at some point? (Or am I just mistaken?)

@olonho In response to someone else, you mentioned some things that I wanted to follow up on. You mentioned some improvements that need to be worked on with k/n:

using the technology in combination with Gradle

. When you integrate with Gradle, will that be when we finally get incremental compilations? You mentioned that Kotlin 1.3 features need to be added before a stable release as well. Is there a place where I can read about the changes coming in Kotlin 1.3? I haven't been able to find a roadmap or anything for Kotlin 1.3. You mentioned that k/n already shares a code base with jvm and js compilers. Getting the compilers under the same arch and sharing an api is one of the first steps to a public API to 3rd party Kotlin compiler plugins (probably the feature I've been most anticipating). How close are we to that as a reality?

How do I add a swift library to a Kotlin/native project?

What software development areas are likely to be supported by Kotlin Native (v1.0 onwards)? Would the following areas be supported: 1. Serverless, a sub area of Server-side 2. Desktop 3. CLI 4. IoT (using a SBC like Rpi, BBB etc), which is a sub area of Embedded 5. Machine Learning 6. AI 7. iOS 8. Android 9. Web Stack (both the web front-end and back-end via WASM)

I have some questions about the gradle plugins. Not sure of best place to ask, so I'll post here. The K/N gradle plugin, 'konan' has a lot of control and options, and you can publish libraries to maven, but as far as I can tell, there's no way to specify those published libraries as dependencies. There's also 'kotlin-platform-native' which can also publish libraries to maven, and can ingest dependencies from maven, but only if they were published by 'kotlin-platform-native'. The 'konan' published dependencies aren't compatible with 'kotlin-platform-native' out of the box.

Any update on if or how Kotlin will handle value types?
