kotlinlang #multiplatform

Hi everyone, is there a multiplatform MVVM semple project? I want to make a pet app to explore KMM capabilities, and if there is such a project, I do not want to reinvent the wheel 😄

Any idea why

@AfterTest

is ran before

@Test

returning JS promise finishes in Node.js test?

Has anyone had trouble with indexing common dependencies? I add a dependency to the common and IntelliJ does't show it though I can write the import and use the class and build with

gradlew build

just fine

I want to write a common library that only has common sourceset and it can be depended from the common main of another mpp project and the codes run on any target. How should I do it?

Anyone have a good example for a multiplatform library project that publishes to NPM? We have a use-case where we want to make a library in Kotlin and use it in a pure javascript repository. I tried this about a year ago and there were some rough edges, particularly around transitive library dependencies, that existed. I've read from bugfixes that it's better now, and I'd really like to see an example. Anyone have an idea?

Has anyone had any success with the

native.cocoapods

plugin recently? I am trying to write a KMM library whose iOS code depends on a cocoapod, which I import using

cocoapods {
  pod("AFNetworking")
}

However

cinterop

gives me

fatal error: module 'AFNetworking' not found

as in this issue. But I don’t think it’s the same problem. Anyone had similar?

What logging solution do you use in your iOS/Android projects? I see that the examples use Napier, but there is no support for macOS and judging from the old opened issues the project seems currently unmaintained. Kermit looks like a good option, but is only a pre-release. So what do you recommend?

Hi guys! I have a question (help request) for you all. Creating a new project and using Kotlin version

1.5.30-M1

with

iosSimulatorArm64

target is throwing me this error:

Task 'embedAndSignAppleFrameworkForXcode' not found in project ':shared'.

This is a new blank project so I was wondering what is wrong there. Any clue?

hey guys, is it normal for kmm project? each time i change 1 line of code and try to rebuild - it's starting the cold build process with redownloading all dependencies etc. sometimes it takes like 40 mins. is it kmm plugin bug or android studio? can't find matching issue in the bug tracker

hey all, need help to understand this particular error message running KMP library on iOS. I am generally aware about memory models (see comments on screenshot) and it normally works. But in some cases, I could not really understand exactly when, I get crash because of this message. So do I get it right: it complains about accessing lambda/closure. I assume the complain comes from inside the async {} block (debug picture is ambiguous), means we are in main thread. The closure was created in the kotlin code before calling this method. Does it mean that closure has been created on Non-Main thread?

I have a shared library and am importing another “shared” module but my code doesn’t see those files (even though the import isn’t in red). Any ideas or articles on KMM gradle? Gradle is the hardest part of KMM for me

Hello, I’m new in KMM (kotlin

version "1.5.10"

). I have an exception in iOS target: Function doesn’t have or inherit @Throws annotation and thus exception isn’t propagated from Kotlin to Objective-C/Swift as NSError. It is considered unexpected and unhandled instead. Program will be terminated. Uncaught Kotlin exception: kotlin.UninitializedPropertyAccessException: lateinit property innerFactory has not been initialized ______________ Am I right that I should add @Throws annotations to all my methods in kotlin shared class? If yes, what exception class should I pass inside @Throws annotation. Thank you

In 1.5.30 one of the new features is Sharing custom cinterop libraries across platforms in multiplatform applications. Can someone explain what this is? It sounds very interesting and like something I’d potentially use, but it’s not really being specific. i.e. can I share cinterop libraries with a Java application?

Does KMM only work in Android Studio or can it work in Intelij Idea as well?

Does anyone know any open source project that iOS can run on Mac M1? I have tried the kmm starter project of Android Studio, but it does not work for me.

Has anyone been able to use the new shared lib integration method in iOS apps with multiple projects? My app is made of a few projects and all of them depend on the shared lib, currently I have a target for a shared framework where I call

copyFramework

in its build phases, this target is then included in all projects. I have tried adding it by changing

copyFramework

to the new

embedAndSignFrameworkForXCode

which didn’t work (project won’t compile because it can’t find the shared lib

No such module 'shared'

. Also tried removing this target entirely and recreating the steps in the blog post in every project, but it also didn’t work.

If I have 2 KMM libraries in a Gradle subproject, is it possible for library A to reference library B by using

dependencies {
    implementation(project(":libB"))
}

When I do this my

compileKotlinIos

task fails with

Unresolved reference

for the classes in libB. Is there any special syntax for adding the common, android and ios flavours of the shared project?

I have some formatting defined in common code between ios and android target and just noticed that they treat special chars differently which messes my impl. I can't even properly paste it into slack, so I'll use screenshots to make it clearer, but take twenti̩
as example. This i̩
with a little dash at the bottom is treated by kotlin as two separate chars, but swift treats it as one. So when I defined formatting which spans across the whole word in shared code with

text.length

, it calculates it as 7 chars. When I use it in Swift, which thinks of it as 6 chars (via

*let* characters = Array(text)

), I get Fatal error: Index out of range
. Any ideas how to work with these?

If I have a KMM umbrella framework, can I include another KMM subproject, which imports a cocoapod using the native.cocoapods plugin? When I try this I get a build error in Xcode:

fatal error: module '<Cocoapod>' not found

But if I include the subproject directly (instead of via the umbrella framework) it works OK. Is it possible to do this using an umbrella framework?

Hello. With a new KMM project, the better way to connect a KMM module to iOS project is to use CocoaPods integration approach or

embedAndSignAppleFrameworkForXcode

gradle task approach?? Are there pros and cons for each from them?

Viacheslav Kormushkin

It depends on your current setup. If you already have an Xcode project that utilizes cocoapods then probably connecting KMM framework as a pod would be a good idea. If you want your KMM module to depend on third-party pods then again cocoapods work. If you don’t want to deal with cocoapods installation and setup then

embedAndSignAppleFrameworkForXcode

task is a solution

I noticed that my gradlew doesn't seem to have a task embedAndSignAppleFrameworkForXcode. I checked gradlew tasks. I have the plugin installed and active and am on a Mac.

John O'Reilly

You need to be using at least Kotlin 15.20 to be able to use that.
