Updated IntelliJ and now my multiplatform project is upset. In my JVM "desktop" source set, it doesn't know about any of the JVM classes anymore. Latest IntelliJ and Kotlin 1.7.10, anyone seen this in recent updates?

Does the compiler hate expected data class constructors? It seems that any expected primary constructor I write (with corresponding actual versions) complains "Expected class constructor cannot have a property parameter", but if I take it away it complains that data classes have to have a primary constructor. Has AS just got itself in a knot or have I misunderstood something (again 😟)

Hello, what is the JDK requirement for KMM? From the docs

Make sure that you have JDK installed. You can get it from its <https://www.oracle.com/java/technologies/javase-downloads.html|official website>.

Can I use e.g. openjdk11 or do I have to use the oracle one?

Hello, How can we consume .c or .h or .a files in Common code in kotlin multiplatform and do some File IO and publish it to IOS and Android ?

Hello, everyone! What is the best architectural approach for KMM? I am interested in the common ViewModel for Android and iOS. I see three main approaches right now: Redux-kotlin, Moko-mvvm and Decompose. Which of these is the best tool to choose for a project from scratch or is there something else?

Is it possible to use an xcframework as my staticLibraries input when using cinterop? I'm getting undefined symbols errors when I try

Hi everyone, I'm starting with KMM to build apps for our company. I'm currently using Azure DevOps for CI/CD with the azure native task Gradle@2 to build the android app. When I look at the documentation, it's written that it is like to build android app since it is Kotlin. The problem when I'm executing the command ./gradle assembleRelease nothing happen. I google it and every example they are using Android Studio and it works like a charm but in the context of CI/CD I can't use the tool 🙂. Can someone help me to understand how in command line ( with gradlew) I can generate a APK please. It's probably a very simple question so thank you in advance !

I’ve found some annoyed thing. We have common kotlin code like

Regex(regexString).matches(valueString)

And someone has sent string with escaped

:

On JVM it works but on JS it leads the error

Invalid escape

: https://stackoverflow.com/questions/63006601/why-does-u-throw-an-invalid-escape-error I think that common code (for an any parameter) must works or doesn’t work in both platforms. It mustn’t be work on JVM and doesn’t work on JS. What should I do?

Hello everyone. I have the following common code :

interface SomeInterface {
  @get:Throws(SomeException::class)
  val something: Something
}

On jvm it compiles well, but the native compiler gives me the error:

This annotation is not applicable to target 'member property without backing field or delegate' and use site target '@get'

How to overcome this limitation? Is there a corresponding YouTrack issue? Thanks.

I'm developing a KMM library and I'm looking at ways to consume it on iOS. Does anybody know if there is a way to do something similar to using includeBuild() in gradle? On Android, we have a dependency on the library that is pulled from a repo. The developer can optionally pull the source for the library and modify the settings.gradle file to swap out that dependency with the source pointed to with includeBuild. This is a popular approach because it allows a developer to quickly iterate when making changes to both the library and app. I'd love to have the iOS app configured in a similar way. Thoughts?

Has anyone tried KMMBridge and run into this issue https://github.com/touchlab/KMMBridge/issues/125

Hey folks, does anyone know/have any source where I can learn more about publishing a KMP library? My end goal is to consume this library on pure JS, I made the code/tests work both for JVM and JS, but the official docs don’t give more info on how to publish (other than to mavenLocal) or to consume the lib.

I have separated the resources into a module which runs entirely on moko-resources. How do I include the generated resources xml files when using

publishToMaven

? Create a separate task to copy the generated xml into android folder? Any help will be appreciated 🙇

❗Hi, everyone ! I am currently running a series of interviews with Kotlin Multiplatform Mobile users, that are using IntelliJ IDEA as a primary IDE for development. If you are willing to spend 30-40 mins on the interview and help us, please, write me in DM :kotlinnew: No pre-requisitions needed ! Thank’s everyone in advance !

in

kotlin.math.MathH

I can see

Double.ulp

but no

Float

counterpart..

Hey folks, is there a way to shrink the binary size of iOS framework? started off with just Kotlin my framework size jumped to 1.4 Mb, upon adding Ktor & SQL delight, the framework size has jumped to 16MB. This is huge. I intended on creating KMM library and using it as my native SDKs shared code, but this is too much of size to be okay with. Is there any way to reduce? and library makers actually okay with it?

I'd like classes defined in

commonMain

to extend specific interface for jvm only. But I'm afraid that's not possible, right? What are the main strategies for this case, other than leaving the interface empty/dummy on the other platform?

Hello! I have written 2 compact apps using the latest iOS & Android stack. But it’s all serious, these are full-fledged applications. A pure shared module KMM is integrated in these apps. If anyone is interested, this is a good opportunity to practice integrating common business logic into applications. P.S. to run you will need: * GitHub Application (The applications use the GitHub REST API) * Firebase account (The applications use Firebase dynamic links) * iOS developer account (Associated Domains cannot be enabled without it) P.P.S. If there are some questions I will be happy to answer. Good luck! https://github.com/keygenqt/kmm-GitHubViewer

hey any ideas how to achieve kotlin data class with default arguments like

data class TestViewState(
    val list: List<Test> = emptyList(),
    val stateText: String = ""
)

so on XCode it would have default empty constructor? like

@State private var viewState: TestViewState = TestViewState()

Currently it is not working because of XCode error :

'init()' is unavailable

It does work as long as it is initialised with values Sorry I am Android dev, not iOS 🙂 (edited) Also made it happen with adding getter to companion object, but this is a hack not a solution

so im trying to add

realm-kotlin

to a tiny test project, and I keep getting this error when I try to reference Realm in my android project.:

Supertypes of the following classes cannot be resolved. Please make sure you have the required dependencies in the classpath:
    class com.radreichley.kmmrepro.Story, unresolved supertypes: io.realm.kotlin.types.RealmObject

I get it in my main project, and this barebones repro project. I’ve copied the build.gradle from their example project (

<https://github.com/realm/realm-kotlin-samples/tree/main/MultiplatformDemo/>

), and verified that their project builds fine locally….

any ideas?

sigh…… so it was a combination of errors. it turns out they dont reference realm directly from android in their example, so their android build.gradle didnt have any settings. I do so I need to add an additional setting in my android build.gradle.. but when I originally had done that it gave an ‘unresolved artifact’ error because their docs are actually wrong. I had assumed I just didnt need it anymore and removed it…. for those following at home, you need to add

compileOnly("io.realm.kotlin:library-base:$version")

rather than

compileOnly("io.realm.kotlin:library:$version")

Hey I added this to the targets: ios() But in iosMain I don't see to have access to the package platform.* Adding all ios targets manually and trying to access that package doesn't help either. Do I have to do anything to access them?

guys with swift background don’t you miss the ability to define static property inside protocol/interface? I use this technique quite often in Swift. Is there a way how to do this in kotlin?

CommonMain classes are not accessible from androidTest sourceSet while they are from iosTest. I am on kotlin 1.7.20 wit Android Studio Chipmunk. I see few references online of people reporting this and seems to be a bug of IDE/platform , how do you workaround this? See example -> IDatabaseRetriever is declared in commonMain

can someone help me understand this section under the code? are they explaining the reasoning behind using the generic Exception class?

Is the Kotlin version used for gradle dependency resolution with Kotlin native? I have a report about not being able to resolve an artifact using Kotlin 1.7 because the project is using 1.6 https://github.com/eygraber/uri-kmp/issues/56

I've had a look at the multiplatform overview, but I'm confused where android sits compared to desktop - jvmMain sounds like it could target both, but they're very different beasts (at least in the sense android consumes AARs and produces resources etc)

I've got more of a concrete example to play with now. I've implemented a multiplatform project targeting desktop and android. I've got a library module that has common, desktop and android code, and an android app module and a desktop app module. Both platforms use the exact same implementation of services using a java library that works on both android and desktop. I'd like to not have to duplicate the code, but I don't know how I can achieve re-use in a multiplatform project world.
