if i have a gradle multi project build, and one subproject is an MPP project, how can another subproject, which is a regular jvm project, depend on the jvm output from the MPP project?

Hi everyone, In the latest 1.3.20 EAP, we've added a few improvements to Multiplatform Projects, including publishing Android libraries (AAR) as a part of a multiplatform library. See the details in the thread. You are welcome to try it and share your feedback!

I’m having trouble consuming a library using single-variant aar publishing in eap-100. See sample project at https://github.com/russhwolf/AndroidLibDemo Here’s my process: 1. run

./gradlew clean build check publishToMavenLocal

in root directory 2. run

./gradlew clean build check

in

app

directory If the library used

publishAllLibraryVariants()

this works fine, but if I do

publishLibraryVariants("release")

I get an error because the debug app build can’t figure out which library variant to use.

Also, another issue: The android tests in

app

fail to build unless I add the library dependency to both

commonMain

and

commonTest

.

Hello, could someone explain what happened to the multiplatform plugin? I guess I missed the last big change, from “kotlin-platform-common” to “org.jetbrains.kotlin.multiplatform”. Before that change, we were supposed to have one module for common, one per platform and then our projects depends on those platform modules. Now with org.jetbrains.kotlin.multiplatform all of the common + platform specific code is built under one only module? Is that correct?

Is there a good tutorial/example-project out there describing how to setup SQLDelight in a multiplatform project (Android/iOS)?

Hi, I’m trying to compile iOS framework with all architectures support Arm64 and iosX64, someone knows how to do it?

Hello everyone! I can’t find anything about how to change the generated framework (ios) name in the multiplatform project build.gradle file. Does anyone know how to do that?

Hello I have an inline function defined in kotlin and compiled to javascript using kotlin multiplatform. It appears as though that function doesn't get exported and so I cannot use it from javascript. Am I correct in making this deduction?

Hello, I am currently trying to make a multiplatform library for our android and ios applications. I have everything except I want to pull in the Firebase SDK for ios using cinterop. I have everything hooked in and working except when I build the linker gives me the following error.

Undefined symbols for architecture arm64:
  "___isOSVersionAtLeast", referenced from:
      +[GULAppEnvironmentUtil isAppStoreReceiptSandbox] in GoogleUtilities(GULAppEnvironmentUtil.o)

Hello guys. I’m working on a multiplaform project, iOS and JVM (I’m not targeting Android directly). Depending on the build type (debug or release) I want to configure the logging level (i.e. to print only errors in release). Since there is no a

BuildConfig

class avaialble, how can I know from

commonMain

the build type?

is it possible to have frontend and android in the same multiplatform project? currently I’ve created mobile (Android/iOS) multiplatform project and when I added

id 'org.jetbrains.kotlin.frontend' version '0.0.44'

I received an error

Cannot add task ':app:bundle' as a task with that name already exists.

this task is created by

com.android.application

Hi guys! Could someone suggest some good Github repository with multiplatform application (Android, iOs) to look at as an example? I know about kotlinconf-app but it looks like it was created before expect/actual feature was released. I'm new to mobile development, usually I create backend apps.

how do dependencies work in a MPP-world? consider a MPP with targets JVM and JS with a

commonMain

dependency on lets call it

A

. What does

A

have to provide in order to be usable as a dependency? Does

A

have ro provide a

.class

as well as a

.js

artifact? Does kotlin kompile `A`s kotlin code into the target's format?

i'd love to you use

jtsgen

, a project written in java that allows to generate typscript typings from java- and kotlin classes. the problem: it uses

kapt

to generate them which drives it more or less impossible. i'd need to use it as

common

-dependency to use the annotations which isn't possible and OTOH using kapt seems to be impossible in MPP, too. But there is a glimmer of hope left: in fact we would need this dependency only at compiletime and there is nothing left at runtime. Can anyone imagine a way to use it?

I just started messing around with multiplatform and have a little example compiling. I wrote a couple common tests and one is failing. I cannot figure out how to get more info (stdout/stderr) or some kind of logging for my tests. I've spent a bunch of time looking for an example or docs and haven't found anything yet. Any help would be greatly appreciated. Thanks!

I cant seem to get the dependencies for iOSMain working. Can anyone help? Using gradle 4.10.1 and kotlin 1.3.20-eap-100 as in the kotlin example layed out by jetbrains.

How can I use

ktor-http

dependency in a multiplatform project? I added

io.ktor:ktor-http

dependency inside the

commonMain

. As

ktor-http

is a multiplatform library itself I expected this should be enough. But for

jvm

I should also add

io.ktor:ktor-http-cio

and for

js

it only works if there is

io.ktor:ktor-client-js

dependency. Why is single common dependency not enough?

Is there a way to grab a

KClass

of an object defined in Kotlin from Swift? I have a function defined in Kotlin that has an argument

type: KClass

and I need a way to call that function from Swift, but not sure how to pass in the type.

Hey, may be someone now, if there is exists a list of all(almost all) MPP libraries? Not only from JB

Hello. I am currently struggling with another issue regarding Kotlin MPP. I am unable to successfully execute a request using Ktor on iOS. It always throws an InvalidMutabilityException. I have a vague understanding of the mutability aspect, but can't figure out why it's being thrown on Ktor. From iOS

kotlin.native.concurrent.InvalidMutabilityException: mutation attempt of frozen io.ktor.client.request.HttpRequestPipeline@3f59548

I've tried downgrading to Kotlin 1.3.10, as that seemed to be suggested on SO. However, it still throws the same exception. Kotlin 1.3.11/10 Ktor 1.1.1 Coroutines 1.1.0

Does anyone here have

@Serializable

working on multiplatform building for iOS? Running into this build error:

cannot access 'Serializable': it is internal in '<http://kotlin.io|kotlin.io>'

I've checked the existing GH issues where it appeared people just had import/plugin issues, but I think I'm doing that right: -

apply plugin: 'kotlin-multiplatform'

-

apply plugin: 'kotlinx-serialization'

-

implementation: "org.jetbrains.kotlinx:kotlinx-serialization-runtime-native:${versions.serialization}"

-

import kotlinx.serialization.Serializable

Something I'm missing?

I’m looking to get started, can anyone recommend any good tutorials?

Maybe a dumb/obvious question: I have a KMPP that I'm currently building for JS and JVM. I expose multiple simple functions (no threading/coroutines or I/O) written in Kotlin in each of these libraries, and then call them on each platform via interop. I'm currently just using JavascriptCore on iOS with the JS artifacts, but my next step is to spit out iOS frameworks too. The project consists of several Gradle modules with interdependencies (i.e., module A has no project dependencies, module B depends on A, module C depends on A and B). Is this configuration supported for KMPPs targetting iOS? If so, is there some example of a multi-module KMPP that spits out either an all-in-one iOS framework, or multiple interdependent framework files?

Does anybody know a solution for this problem? https://stackoverflow.com/questions/54327143/how-to-create-a-dynamic-proxy-in-kotlin-common-code

Is there a way to depend on a dependency with

0.3

`.metadata`while being on

0.4

? I'm trying to use

ktor-client-ios-iosx64

, but it won't import with

GRADLE_METADATA

enabled.

I’m having a strange issue: Whenever I do a Gradle sync / refresh in a MPP project, all the iOS Native dependencies (i.e. WatchKit) are re-downloaded. It seemed to stop a few days ago, but now it’s doing it again. Anyone else experience this?

@h0tk3y Is this now the correct way of declaring ios preset dynamically?

def iosTarget = project.findProperty("IOS_TARGET")
kotlin {
  targetFromPreset(presets[iosTarget], "ios")  {

  }
}
