Hi! Choosing between CLion an IJ IDEA for Kotlin/Native development, are there reasons in favor of CLion, and cases not supported in IJ IDEA?

Is there an easy way to do String normalization in Kotlin? I am looking for something similar (or better identical) to the JavaScript String.prototype.normalize function: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/normalize Thread in Slack Conversation

How can I set icon for macos application? By

info.plist

I’ve set icon for application in Launchpad, file -

/Applications/my.app/Contents/Resources/main.icns

If I try to set by

val iconUrl = NSURL(fileURLWithPath = "file:///Applications/my.app/Contents/Resources/main.icns")
app.setApplicationIconImage(NSImage(contentsOfURL = iconUrl))

I have NPE If I try to set by

val iconUrl = NSURL(fileURLWithPath = "file:///Applications/my.app/Contents/Resources/main.icns")
app.setApplicationIconImage(NSImage(byReferencingURL = iconUrl))

I have error

Cannot lock focus on image <NSImage 0x7f9d75af1370 Size={0, 0} Reps=()>, because it is size zero.

How I can set icon?

remove

file://

less familiar with macOS and how to get that main.incs file though

Hi everyone

TfLiteTensorCopyToBuffer(output_tensor, voidPtr1, 5u)
val stableRef3 = voidPtr1.asStableRef<Map<Int,Any>>()
val outputs1 = stableRef3.get()

when I try to print this outputs1 variable, I am getting "trying to access inaccessible/invalid location" what is wrong with printing above variable to console.(I have disposed stableRef3) I don't know what memory leak is generated by printing a variable to console.

Discovered a issue that makes Kotlin Native not work well with Container/CI systems (lack of caching for the Kotlin Native toolchain): https://youtrack.jetbrains.com/issue/KT-39751

Hi everyone, does anyone know how to access the data classes of Kotlin native in native c code? The header files generated by kotlin native is very complex and I am not able to decode it. example : listof() in kotlin native becomes libnative_kref_kotlin_collections_List as shown below

typedef struct {
  libnative_KNativePtr pinned;
} libnative_kref_kotlin_collections_List;

I can access libnative_kref_kotlin_collections_List in my c code by including the header but I am not sure on how I can pass listOf strings to this. Is there any documentation around how to access and use the data classes from Kotlin native in c code? I am trying to write something like below in my c code : vector<string>recentTasksV; recentTasksV.push_back("hello"); libnative_kref_kotlin_collections_List recentTasks = libnative_kref_kotlin_collections_List(recentTasksV) ;

Has anyone done building macOS application with bitrise.io?

How to force Kotlin/Native (or cinterop tool) to use

armeabi-v7a

instead of

for

androidNativeArm32()

targets?

I am getting DllNotFoundException runtime error when I am trying to load .dll built by kotlin/native in my c# windows app. Has anyone faced same issue? I followed https://github.com/diteix/kotlin-native-import

I was able to use the .dll generated by kotlin/native in a windows console c++ app. But, I am not able to use it in a c# app. so far here is what I have tried : • I can load the .dll • I can access the pointer like (libnative_symbols<- the entry point) • from this pointer I was easily able to access the function as libnative_symbols()->root.kotlin.packagename.functionName() • can't I use the pointer to access the function in the same way as above in a c# app? It seems that pointers in a c# app is different in c++ app and so far what I have understood is, we need to define a struct by looking into the header file manually, which is not a nice solution. Has anyone tried it? can I access the function from this pointer in a simpler way?

It's annoying as hell, my ide is full of warnings. I tried it with the official example and once you add any dependency you get warnings when you use a type: https://github.com/PaulWoitaschek/mpp-ios-android/commit/7fa8c84b12cae3f97e6c214a7b900e8394f4535c#diff-7057962a2585ff72f8f37c7ae74a9ca3R16

Its really werid. iniitally it works but when you sync gradle, it creates a jar and then it's broken and always leads to the jar. I don't get why it stops connecting the sources

Here we go https://youtrack.jetbrains.com/issue/IDEA-244682

I have a dll generated using Kotlin native to be consumed in some another windows C++ app. I am trying to redirect dll console logs to host logger which is not console based. For this task I was passing a function pointer to a kotlin class in dll but could not figure out a way in CInterop to do that. Any pointers on this?

I’m using Fastlane to generate my screenshots using Xcode’s XCUITests. I have a shared common framework written in Kotlin. When running mine, I get this error:

Snapshots
    ✗ testSnapshot, App crashed in konan::abort()

I’m running the same tests from inside Xcode or with the command line and it’s working fine. Only with Fastlane does it crash. How can I see where the common code crashed? Where is this happening? Thanks!

Is there a way to add a new target to ktolin-native without rebuilding from source? That is, if I download the macos kotlin native build, can I perhaps add the definitions to add a target? Specifically, I was wondering if I could add the mac catalyst option, since it ought to just be variations on the targets already defined in konan.properties

I’ve made macOS application with Info.plist The file OK

$ plutil Info.plist 
Info.plist: OK

But in application console I can read

system_profiler[36860:3573263] There was an error parsing the Info.plist for the bundle at URL <0x7f8d0e73dde0>: NSCocoaErrorDomain - 3840

I think I have got a conflict app.kexe and Info.plist How can I get detail error message?

Are there any other desktop applications built with Kotlin/Native besides my own Wraith Master project? I assume there are, but I can't name any. Slack Conversation

Is there still no way to override something like

UIView.intrinsicContentSize

in a

UIView

subclass in Kotlin? You can override (some?) functions with the

@ObjCAction

trick but what about extension properties?

Hi guys. I'm wondering how to throw exception from suspending function in Swift using Kotlin 1.4-M3. Here's the setup: I have a Kotlin interface like this:

interface Foo {
    @Throws(CancellationException::class, MyException::class)
    suspend fun bar(param: Int): String
}

This interface gets translated thusly in Swift:

public protocol Foo {
    /**
     @note This method converts instances of CancellationException, MyException to errors.
     Other uncaught Kotlin exceptions are fatal.
    */
    func bar(param: Int32, completionHandler: @escaping (String?, Error?) -> Void)
}

I can (and do) implement this interface in Swift, creating a class with coroutine functions that I can use in Kotlin (btw, blown away by the fact that it actually works, amazing job!). What I don't see, however, is how can the

bar

function use the

completionHandler

with a

MyException

. In other words, I need to express a async failure in Kotlin. In other other words, the bar function may fail asynchronously, and I need the coroutine (not the callback) to throw a

MyException

:

class SwiftFoo : Foo {
    func bar(param: Int32, completionHandler: @escaping (TCPSocket?, Error?) -> Void) {
        someSwiftAsyncApi(param) { result in
            if let result = result { completionHandler(result, nil) }
            else { completionHandler(nil, MyException("someSwiftAsyncApi failed!")) } // TYPE ERROR
        }
    }
}

This does not compile because

MyException

is not a Swift

Error

. Any way to do this?

I’m using koin in my project

Why posix.* package hasn't got some variables in windows?

import platform.posix.NI_NUMERICHOST
import platform.posix.NI_NUMERICSERV
import platform.posix.getnameinfo

allowed in macOS/linux but for windows I have to use

import platform.windows.NI_NUMERICHOST
import platform.windows.NI_NUMERICSERV
import platform.windows.getnameinfo

How can I write the same code for both platforms? PS: 1.3.72

I've created minimal example for the problem: https://gitlab.com/alxt/kotlin-win-com Can anyone help with COM in windows?

https://youtrack.jetbrains.com/issue/KT-40545 Bit of a meta issue, but something that I just noticed and that should probably be fixed.

About circular dependencies, I have found this helpful comment and checked out klib/manifest/depends for my cinterop libs A, B, C. • Starting from a clean environment, If I call

cinteropA

, its depends are ok. • Then I call

cinteropB

, and I can see that its depends include A ? Why would they do so? • If I call

cinteropC

, it will be set to depend on A and B... 😄 Now I can definitely see the circular dependencies, but they come from the plugin - not me. How can I workaround this problem? @Artyom Degtyarev [JB] It even breaks with a single cinterop library. • Clean env, call cinterop task, depends are OK • Call cinterop task again, depends now include the lib itself! • Call cinterop task again, circular dependency detected.

I'm trying to build Kotlin/native with experimental targets (zephyr_stm32f4_disco) so that I can eventually run the blinky example on my development board, however my build fails with experimental targets. The resulting error...

A problem occurred evaluating project ':common'.
Unknown target name: zephyr_stm32f4_disco

Hi guys, any thoughts on that?

Will it one day be possible to have

compileOnly

dependencies in K/N? The idea is to provide extension functions in a library for classes that may or may not exist in the library consumer’s project depending on other libraries that are included.
