Hello, Is there any way to generate the framework for for Debug variant I mean I always have to use

./gradlew build

which buids all variant I tried

./gradlew buildDebug

but it does not generate framework for me

Hello everyone, how should I interoperate with C++ in the native target of the kotlin-multiplatform? I need to call a library whose header file is C++, the library is a bit huge, so it is unrealistic to manually change it to a C header. In addition, I am a newbie to C/C++, so this question may be a bit stupid.

I've got an annoying problem, so with the latest IntelliJ Ultimate, I create a brand new multiplatform project, compile and run, all works. Then I add a new library to the

commonMain

source set, and IntelliJ doesn't seem to know about them. Auto-complete won't recommend them. I Can add the import manually and it's fine, but the IDE doesn't seem to know about it. I have tried invalidate and restart, deleting the

.idea/

directory and re-importing the project, doesn't matter. I've also tried on separate computers & OSs (OSX & Windows) and its the same. Is this something anyone else has run into?

Hi all, Wondering if we can call API synchronously using Ktor Engine. Actually, whenever I'm getting 401 Authorization Token Expired error, I've to call Login API implicitly from Authenticator. Now this api call need to be called synchronously as after getting login API response, i've to update the header with Auth Token and return the request again from authenticate method.

Update : I was not aware of ktor-client-auth, let me check if it'll help me.

Thanks

Hi, I Have a .json file that is placed in scr/commonMain/resources, while I would like to start desktop tasks [run], [assemble], [build], I’ve received an error that this file doesn’t exist. If I’m doing this for android everything is working correctly. Is there a way to solve it ?

Hi all, I was wondering what are the best practices for versioning a KMM application. I'm the only mobile developer in our company and I'm trying to share most of the code with KMM, however I will not be able to work on the Android and iOS app at the same time. My question is: how do I tag my releases? Do I tag the android app with, for instance, android-1.0.0 and iOS with iOS-1.0.0 afterwards? Is there any better way to do it? Maybe I should publish the shared library in a maven repository and a Cocoapods repository and use it in separate projects? I struggle to find some examples and best practices for this case.

Hey I am new in the world of Kotlin Multiplatform mobile. I have experience in development of android field. I am trying to connect Android application and Ios application. I searched and see Ktor is the way to fetch data from server. In android we use Kotlin Sealed Classes for Handling API Responses example in your application and in ios side team use Understanding Swift closures and asynchronous request functions similar to these. I am little bit confused, How can I use this way in common module to use both platform because both platform have Interceptor and many more things. Do I need to write everything from scratch? or Is there any way we can use existing way. My both platforms application is huge project. I don't won't to replace the code. I want to start new api call throught KMM. Any suggestion would be helpful for me. Thanks

Hey all, it's been a few months since I setup a KMM project for testing, we are getting closer to project start time so I decided to set it up again just to refresh my memory and to potentially update the libs etc. I added the sqldelight and the kotlinx-serialization-core, I get this error in sync:

Could not resolve org.jetbrains.kotlinx:kotlinx-serialization-core:1.2.2

if I build it works for Android, but it doesn't work on iOS. I get this error:

The following build commands failed:
	PhaseScriptExecution [CP-User]\ Build\ shared ... (in target 'shared' from project 'Pods')

I am using CocooaPods if that are in interests here, I am a bit confused and not sure were I should look now, any ideas?

Any tips on handling how to show licenses of 3rd party libs used in KMM module? Normally I’d use

CocoaPods Acknowledgements

and

oss-licenses

, but I’m a bit doubtful that either one would work in this scenario… or at least the

CocoaPods

one

Hello, I'm trying to build a kmm library for android and iOs that includes a webview. Does this work for iOS or macOS/other native only?:

import kotlinx.cinterop.*
import platform.WebKit.*
import platform.Foundation.NSZeroRect

class myWebView : WKWebView(frame = NSZeroRect.readValue(), configuration = WKWebViewConfiguration())

Hello! I'm building a multiplatform project targeting ios, android, jvm, and eventually js. The idea is to create a multiplatform library with the network layer and some business logic in it that I can share across my different projects. I also want to share this library with a desktop compose app I'm starting to create. I'm looking for a decent (or suggested) library to do DI in the multiplatform library. So far, I've found that Koin and Kodein have support for multiplatform. Is there a preferred library for DI on KMM? Do you prefer one over the other? why? thanks in advance.

Hi guys, are there any multiplatform location libraries available ?

Hello everyone. I have a KMM app, the iOS project is able to consume functionalities from the shared module. Now I’m trying to add Swift Package into my iOS project. Can I make my swift package also recognize the shared module ?

Hey there! In our project, I noticed that classes like

com.foo.SomeClass

will be exported in iOS with Swift names

SomeClass

. If our module exports a lot of those, and all the swift files import the module with

import SharedCode

, there might be some conflicting Swift classes or classes from other libraries. Does anyone have a good solution for this? Something like a namespace, or exporting multiple swift packages, or other approaches?

Is there currently a way to export iOS build artifact directly to swift package manager?

Hey I am learning Kmm with cocoapods integration. My studio is generated podfile automatically when I added the KMM module. Sometag I understand but some are not. Can someone guide me use case of attributes and also did I miss any attributes for my ios project. Podile

1. I have doubt in source, vendored_framework, libraries, module_name and what is pod_tarvet_xconfig. 2. Did I miss any other attributes for my ios project? 3. Can someone explain me how this pod is know where the framework is? If I add this pod file to different repository so how can I connect them

Hi folks, quick question. How come i can import java.util.UUID in commonMain? In commonMain:

public expect class UUID

In jvmMain

public actual typealias UUID = java.util.UUID

In another part in commonMain:

import java.util.UUID

public data class Account(
    public val uuid: UUID,
    public val number: String,
    public val firstName: String,
    public val lastName: String,
    public val identityKey: String
)

What are the plans for Kotlin and multiplatform inline classes, now that inline classes have been deprecated?

I have been trying to find the correct place to put my

lint.xml

file in my KMM project to allow me to suppress some of the main Lint errors (in particular the Graph generated classes are causing all sorts of issues for me). I see errors like this:

/Users/MWolfson/.../shared/build/generated/sqldelight/code/AppDatabase/commonMain/com/company/eventable/cache/Event.kt:10:1: Lint error > [indent] Unexpected indentation (2) (should be 4)

So I have created a

lint.xml

file with the following:

<?xml version="1.0" encoding="UTF-8"?>
<lint>
    <issue id="indent" severity="ignore"/>
</lint>

and I placed this in the following directory:

/Users/MWolfson/.../shared/lint.xml

BUT this doesn't have any effect?! What am I doing wrong? I have tried all sorts of permutations of values in the ignore file, and also tried to put that file in multiple different locations. Anyone that can help me with this Lint config challenge I would be eternally grateful. Also added this to my

shared\build.gradle.kts:

android{
...

lint {
    quiet = false
    abortOnError = true
    lintConfig = file ("./lint.xml")
}

I have a few simple C files that I would like to compile and use with cinterop, and I have a few questions 1. Is it possible to actually compile those C files as a part of my Gradle build? If so, what is the best way to go about it? 2. Assuming these C files compile to a static library and I include them in my Kotlin target, will they work on Android? Or do I need to write separate JNI bindings for Android, and then merge the interfaces into a cross-platform abstraction?

Hi, Working on formatting date in a project. For Android and IOS

internal expect fun formatDate(value: Long, format: String): String

is straight forward. For JavaScript in Kotlin/JS is there any equivalent for formatting the date.

kotlin.js.Date

has no formatting capabilities.

kotlinx-datetime

also seems to lack formatting capabilities. Am I missing something trivial?

Hi, folks. Im working on a kmm library. I i have a common main and some code in jvmMain targets. I want to produce also a ios/android variants based on common code. It is necessary to define the androidManifest.xml? I was wondering since i do not need currently extra code in my androidMain target if could omit it somehow. I can provide some snippets of my configs if it's needed.

Anyone got a Kotlin Multiplatform to work with Sonarqube?

Hi everyone, In Koltin multiplatform project, I have an object class in shared module in commonMain and i am trying to access and update some variables of that object class from native android and ios project, From android its working fine, but its showing this exception in ios project:

Uncaught Kotlin exception: kotlin.native.concurrent.InvalidMutabilityException: mutation attempt of frozen com.buildingengines.sharedmoduletenant.core.service.KmmServiceLocator@1518f08

How to solve this problem, cant we access and update shared module object class variables from swift ios? any workaround for this, Guys Please help. i am stuck with this. I need singleton class in shared module and then inject some native android and ios dependencies into that class on app startup.

What is the best IDE to use for KMM? The FAQ suggests Android Studio, while also saying that one can use Intellij Ultimate with some limitations. Android Studio works for the most part, but there's no support for Swift. I typically do most of my iOS dev in AppCode, and I was happy to find a KMM plugin for AppCode. However, opening the project created in Android Studio in AppCode with the KMM plugin installed resulted in a number of issues, such as the project requiring conversion to a KMM project, facets that cannot be loaded, and a lot of red in the Kotlin syntax highlighting. I also tried creating the project in AppCode, but after restarting AppCode and reloading the project, I got the same facets cannot be loaded error ("unknown face type" kotlin-language and android). [edit: I updated AppCode while composing this, and just needed to reinstall the KMM related plugins]. Most of these are probably just growing pains for KMM, and I can open tickets for these things, but as someone just getting started with KMM, which IDE should I stick with for the least amount of difficulty?

Hello! I have an already present multiplatform project which I want to a ktor server module. I have a core multiplatform module like this:

plugins {
  kotlin("multiplatform")
  kotlin("plugin.serialization")
}

version = "1.0.0"
java.sourceCompatibility = JavaVersion.VERSION_1_8
java.targetCompatibility = JavaVersion.VERSION_1_8

kotlin {
  js(IR) {
    browser()
  }

  jvm()

  sourceSets {
    val commonMain by getting {
      dependencies {
        implementation(kotlin("stdlib-common"))
        implementation(Deps.kotlinxSerialization)
      }
    }

    val commonTest by getting {
      dependencies {
        api("org.jetbrains.kotlin:kotlin-test")
      }
    }

    val jvmMain by getting
    val jvmTest by getting
    val jsMain by getting
    val jsTest by getting
  }
}

And now I did add this new ktor module

plugins {
  kotlin("jvm")
  kotlin("plugin.serialization")
  id("application")
}
version = "1.0.0"
java.sourceCompatibility = JavaVersion.VERSION_1_8
java.targetCompatibility = JavaVersion.VERSION_1_8

dependencies {
  implementation(kotlin("stdlib"))

  implementation(project(":core"))
  implementation("io.ktor:ktor-server-core:1.6.1")
  implementation("io.ktor:ktor-server-netty:1.6.1")
  implementation("io.ktor:ktor-serialization:1.6.1")
  implementation("ch.qos.logback:logback-classic:1.2.6")
}

application {
  mainClass.set("ca.sebleclerc.api.ApplicationKt")
}

When I execute

./gradlew server:run

I get this error:

* What went wrong:
Could not determine the dependencies of task ':server:run'.
> Could not resolve all task dependencies for configuration ':server:runtimeClasspath'.
   > Could not resolve project :core.

I understand it can’t match anything that is produced by my core module but I can’t find anything to make it work. I did tried a few things but nothing worked… Anybody have any clue? Hint? I am using Kotlin 1.6.20-M1 Thanks for the help 🙂

hello all! I’ve been trying to understand this issue: • when trying to run the iOS app from Android Studio the simulator opens but the app doesn’t install if you go to run configurations there’s an error there saying “Error: Selected scheme “iosApp” does not support “iphonesimulator”“. while trying to debug this I’ve noticed that this happens due to cocoapods; I’ve tried the pod like

SwiftLint

and everything works, but if I use other ones like

AlertToast

or

SDWebImageSwiftUI

it doesn’t work. any ideia why? I’m able to run the app both from xcode and to install it in a real device

Hey guys, I am trying this kmm-basic-sample from the kotlin sample. I am trying to Add and configure Kotlin CocoaPods Gradle plugin from the offiical doc. I am trying to add this line

kotlin("native.cocoapods") version "1.6.10"

and I am getting-this weird issue. Can someone help on this

org.gradle.internal.exceptions.LocationAwareException: Build file '/Users/vmodi/Downloads/kmm-basic-sample-master/shared/build.gradle.kts' line: 1

Is it possible to use expect and actual with a static function like

SomeType.fromByteArray(data: ByteArray)

? Because I know you can’t expect companion objects
