Are there any mock library that supports multiplatform(jvm/native), or any plans to release one?

Hello everyone, I am trying to generate Multiplatform code at build time. can KSP do this? or do I need to dive into Compiler Plugins?

Hi guys, I have ktor set up in my kmm project, and was wondering how I could make my API urls configurable, since I want to use a different api url for development compared to when I'm building the app for production. Any tips on how to achieve this?

Hello, just updated to latest

Android Studio Bumblebee | 2021.1.1 Canary 2

And it seems the KMM Plugin isn’t compatible 😞 Do we have anything in the roadmap when a new compatible version of the plugin will be available?

Plugin 'Kotlin Multiplatform Mobile' (version '0.2.5(203-1.5.10-829-IJ)-120') is not compatible with the current version of the IDE, because it requires build 203.* or older but the current build is AI-211.6222.4

the use case is to add additional header for each request executed, let’s say Authentication but with a custom header key

Hi Everyone, I have a project in Android and iOS with 15 local dependencies, in Android we use modules which are part of the project and in iOS we use Swift package manager. we have a

core-library

in both android and iOS, we want to convert this into a KMM module and use the same on both iOS and Android as our journey of migration to KMM. as currently I saw we can only import as

.jar

in Android and

.framework

in iOS, is this true or can we have the complete module added to our project ?

Is there a way to use viewmodel defined in common code with Hilt? It needs a @HiltViewModel on class and @inject on constructor.

Hi Everyone, we are using "native-mt" version of coroutines for our Kotin/Native ARM. On the kotlin doc, it mentions "native-mt" has memory leaks. Has it been fixed in "1.5.0" coroutines? I also see that "ktor" always uses "native-mt" version for kotlix.coroutines.

I followed the "Create a custom compilation" to add a new

jvm

custom compilation. It's not clear to me how can I add that new custom compilation as dependency in another module. More details in 🧵

I am adding latest ktor version 1.6.0 and its not being recognised in my KMM project, 1.4.0 is working fine, what could be the issue, anyone else faced this issue ?

hey guys, what is the best way to fix red gradle configs in kmm project? apart from cache clean/rebuild/cleaning build dirs (because it didn't help). it builds fine, but these highlightings are annoying

Hi everyone, is there a way to modify generated swift name of Kotlin class? the usecase is I have a

open class SomeOpenClass

in my library named e.g.

MyKmmLibrary

if the user use it in the kmm app the open class will have the swift name

MyKmmLibrarySomeOpenClass

which is terrible, is there a way to force it to be named just

SomeOpenClass

?

does anyone use ktor server in a multiplatform environment? i know the CIO client is able to work like that, not sure about the server. also asked in #ktor

Hello, Today I update the KMM plugin and the android studio And retry again to build a new KMM project. The project build and it works great (this is the first time that the default kmm project build successfully from the beginning ♥️) But I have a problem is that I don't have macOS and I want to modify the iOS UI code How to achieve this using windows ?!

Hey! Does someone know where https://github.com/touchlab/SQLiter is hosted now?

Anyone using Android Studio Bumblebee C2 and KMM plugin? Just created a new project with it and can't get the ios app to run.

Hello, is the Jackson library supported on KMP projects? If not, is there any guide helping with the conversion of a Java based Jackson project to Kotlin / Kotlinx Serialization?

HI,

public class HeaderInterceptor implements Interceptor {

    @Override
    public Response intercept(Chain chain) throws IOException {
        Request request = chain.request();

        request = request.newBuilder()
                .addHeader("headerKey0", "HeaderVal0")
                .addHeader("headerKey0", "HeaderVal0--NotReplaced/NorUpdated") //new header added
                .build();

        //alternative
        Headers moreHeaders = request.headers().newBuilder()
                .add("headerKey1", "HeaderVal1")
                .add("headerKey2", "HeaderVal2")
                .set("headerKey2", "HeaderVal2--UpdatedHere") // existing header UPDATED if available, else added.
                .add("headerKey3", "HeaderKey3")
                .add("headerLine4 : headerLine4Val") //line with `:`, spaces doesn't matter.
                .removeAll("headerKey3") //Oops, remove this.
                .build();

        request = request.newBuilder().headers(moreHeaders).build();

        /* ##### List of headers ##### */
        // headerKey0: HeaderVal0
        // headerKey0: HeaderVal0--NotReplaced/NorUpdated
        // headerKey1: HeaderVal1
        // headerKey2: HeaderVal2--UpdatedHere
        // headerLine4: headerLine4Val

        Response response = chain.proceed(request);
        return response;
    }
}

I have something like this custom Interceptor in my Android retrofit interceptor for headers, I am converting this logic to ktor and want add an interceptor there, I could not find a proper solution, the way ktor docs suggest is we need to create a custom feature (Plugin) and install it while instantiating the client, any help or direction is appreciated

I need to log the screen size of my iOS device.

UIScreen.mainScreen.bounds.size

bounds

should be a

CGRect

and

size

should be a

CGSize

, but

size

is an

Int

. This seems like a bug. Any other ways to get the screen size?

This might sound a noob question but just starting on KMM, I want to create an APIClient as shared module for Android and iOS I need the following features • It should have local SSL data encryption • InternetConnectionCheck Interceptor • ErrorHandlerInterceptor • RetryRequest After RefreshToken Interceptor • Few other custom interceptors Earlier I was writing my APiClient in the

commonMain

but as I can see it does not support addInterceptor property by default, which is available in OkHttp for Android. So the new plan I had is create an expect class APiClient in common main and implement APIClient for Android on AndroidMain with OkHttp engine and APiClient on iOSMain with IOS Engine. Is this approach right ? or am I missing some part ?

Anyone know how I can get to use GsonSerializer for ktor? https://stackoverflow.com/questions/67968603/how-to-get-to-use-gsonserializer-for-ktor

While trying with KMM Tutorial , but with slightly different model… I got the below error when performing deserialization for iOS (okay in Android though). https://stackoverflow.com/questions/67969562/kotlin-native-concurrent-invalidmutabilityexception-mutation-attempt-of-frozen Any idea what cause the problem? Or is the a Kotlin-Native bug?

I am using kotlin multiplatform v1.5.10 to build binaries for Android and iOS. I have 2 kotlin native project (a core and a client). In the core project I have a singleton (using kotlin 'object' with threadlocal annotation), which is find in the client. The problem is at the client export to Apple Framework via cocoapods plugin (v1.5.10) this singleton present in core seems not being exported and is not reachable through xcode. The module is well exported and other class are visible. I guess it's because the singleton is kind of declared as unused. Do you know how I could tell cocoapods plug-in to keep this singleton or to not remove unused code ? Many thks

Our model has multi fields with multiple name, I want to use multi serial name, but I can not, any way to do that? thank alot

Hello, in android projects I always create a Java/Kotlin module for the domain layer and I add it to the data layer(which is an Android module) . Now I want to do this process for a KMM project but when I create a Java/Kotlin module and add it to the shared module (commonMain) the iOS app won’t be built. Please guid me. Thanks

Repo and CD Strategy I saw some talks about this over a year ago, but I'm wondering if more of a best practice has been discovered since. I would like to know the best way to structure a repo for a new shared module that will be accessed by 2 existing native apps. One Android, one iOS. This is my current plan: Store it in the android repo. To build for iOS, pull down the android repo, and set the folder path to the common build script. For CD, publish the pod to a private repo (with it's own versioning an release process) and adjust the location of the pod for the CD build.
