Hi All, I am new to Kotlin I have question. Is it possible to create IOS application using Kotlin??

BTW, guys, I’ve been using K/N for creating an iOS framework on a side project and I’m positively surprised 👍: that’s a nice job you did there. I’ll give a talk about that at http://romobos.com next week

question (especially after reading your interesting article @olonho): as far as I understand, workers are not available in Kotlin/JVM... Isn’t that a major cause of incompatibility between Native and JVM implementations?

I love that with Go I can build a simple statically build CLI tool that I can just run without installing anything else. Is there an equivalent ability to do that with Kotlin?

Hello, I just saw that this PR (https://github.com/JetBrains/kotlin-native/pull/1280) got merged, which ads support for multiplatform projects to the gradle plugin. Which

konan.version

do I have to use in order to give that a try?

is my memory correct when it says that kotlin native doesn’t work with c++ shared libs?

I have CLion installed, however, I am not able to find the Kotlin or Kotlin/Native plugin in the plugin manager. Do I have to download them directly from JetBrains Plugin site?

When is the next kotlin-native release planned? That release should allow for kotlin-native + multiplatform projects right?

How would I debug the calculator sample on iOS? https://github.com/JetBrains/kotlin-native/tree/master/samples/calculator

Hello. I'm sure it's been asked before but I didn't manage to google anything and there is no slack history. I'm trying to do basic C interop with stdio.h and get this:

$ cinterop -def stdio.def -o build/c_interop/stdio
KtFile: stdio.kt
$ konanc src/* build/c_interop/stdio-build/kotlin/stdio/* -library build/c_interop/stdio
KtFile: stdio.kt
KtFile: hello.kt
llvm-lto: error: Linking globals named 'kobjref:stdio.__sbuf.Companion': symbol multiply defined!
... kotlin stacktrace

Is it something I'm doing wrong or it's a known problem?

(also

konanc -version

prints

kotlinc-native 1.2-SNAPSHOT (JRE 1.8.0_152-b16)

however I'm sure I downloaded kotlin/native from v0.5 release on github, it's a bit confusing why versions are different 😕)

Did you guys already release a new version of the kotlin native gradle plugin? using

org.jetbrains.kotlin:kotlin-native-gradle-plugin:+

I get

Server returned HTTP response code: 403 for URL: <https://download.jetbrains.com/kotlin/native/builds/releases/0.6/macos/kotlin-native-macos-0.6.tar.gz>

Hi! Checking in on callbacks/function-pointers with struct-by-value returns. From the INTEROP.md readme:

Callbacks

[…]

Note that some function types are not supported currently. For example, it is not possible to get pointer to function that receives or returns structs by value.

Is this functionality on the radar/roadmap, or more of a “we’ll get to it someday” status?

I saw the

0.6

has been released on the github without a release note. Awesome work, JB team! I suppose the release note will be there soon? 🙂

curious how Konan and Kotlin gradle plugin will work together in multiplatform/multimodule setup

Given I have a multiplatform project with a

native

aka

iOS

module. I know that I am able do Objective-C calls from my kotlin code. I can even import classes from the

UIKit

etc. . But how does that work? Is it related to the interoperability which generates kotlin bindings based on the specified

konan.target

?

Hi everyone, do primitives from Kotlin/Native translate correctly to iOS at the moment? I am trying to build a prototype framework and the values set in the framework are not the same that the view is showing.

when is the kotlinx.coroutines going to come out for Kotlin-native?

CLion is telling me that my kotlin-native plugin is deprecated today, tells me to download the plugin from somewhere else, and then tells me the new version isn't compatible with my CLion version (and I try to update CLion, but there are no new updates. Not sure what to do.

Hi, tried that https://github.com/JetBrains/KotlinMultiplatformPlayground Have a problem. I tried adding the following imports to see whether it works or not:

import platform.Foundation.*
import platform.UIKit.*

The Foundation part could pass the build while the UIKit can’t be resolved by gradle. Does it mean that I need to build the UIKit lib on my mac?

@olonho Are there any plans to improve the iOS debugging story? It seems debugging works with lldb console commands, and you can set breakpoints in iOS code using the UI and step into Kotlin code. This is still a really hard sell to my iOS team though. Are there any plans to somehow improve debugging in xcode so that it's more user friendly (may not be possible), or provide a more complete debugging experience in a JetBrains IDE?

Anyone know why I can't invoke wasm as a target I just get

exception: java.nio.file.NoSuchFileException: /opt/kotlin-native/konan/targets/wasm32/native

as an error

@Tobi Hi, you mentioned here https://www.novoda.com/blog/kotlin-goes-ios/ “Kotlin/Native comes already with bindings for a few iOS libraries, for example the NSTimer”, could you kindly tell where the list of such bindings/libraries can be found? Cool article and example btw 🙂

I'm building a multiplatform project for js/jvm/ios that expects a sealed class. It seems to build fine for JS and JVM but for iOS i'm getting "exception: java.lang.AssertionError: expect class WriteLog: Super class should be any: actual class Operation". Are sealed classes or class hierarchies going to be supported for native compilation? Or is this a bug that should be reported?

Are coroutines supposed to work in Native modules? Trying to create my own simple implementation for iOS, this simple declaration alone in Native (or common) module crashes compiler:

fun launchAsync(context: CoroutineContext, block: suspend () -> Unit) {
    TODO()
}

With

exception: java.lang.Error: Invalid module

https://github.com/Albert-Gao/kotlin-native-mobile-multiplatform-example Setup a project of sharing code between iOS and Android with the tests, it’s a little bit different than the others because the

Shared

code has

common

,

ios

and

android

, which I use multiplatform approach for ios and android only. All parts works perfectly now. Thanks for all the help!

hello, any rtm pointer to an example where i can pass kotlin type and populate in C and use it back in kotlin ?

@Simone Civetta hello, i try to build ios framework in your project but I get an error
