Looking to exchange some ideas around a strange KMM behaviour. We had this function in a commonMain source for Android and iOS code;

private fun String.strip() = this
    .replace(oldValue = "https://", newValue = "", ignoreCase = true)
    .replace(oldValue = "http://", newValue = "", ignoreCase = true)
    .substringBefore(delimiter = "?")

which was called from the same file on a String. This has been working fine until recently. Now suddenly, the function does nothing ("https://" prefix is not removed from a string) on Android but works like before on iOS. I think it was after bumping to Kotlin 1.7.20, AGP 7.3 and compileSdk 33. What could be happening here? Theory: Is something causing it to call through to the Java String.strip() function instead, which was added in Java 11? Does it have to do with desugaring?

Regard https://kotlinlang.slack.com/archives/C3PQML5NU/p1663865511120329 , is the Kotlin/JS compiler open source? How can we get this fixed?

Hello, is there any kmm support for what this project does ? https://github.com/yshrsmz/BuildKonfig

Hey everyone 👋 I'm starting to see this on all my repos on Github Actions, including Arrow.

Invalid device: Apple Watch Series 5 - 44mm

8405 Any ideas how to fix this? It's been blocking a couple projects, and I've tried a couple things but none seems to work. If I check the MacOs runner to list the simulators it lists this specific simulator, and it's amongst the list 🤔

Hey everyone, how can I access

Kotlin enum

from Swift

Hi all! I’m trying to make a multiplatform library which is pure Kotlin (aka no platform-specific code), exported for Android too. To be honest, it is a JVM-pure library so it doesn’t even need to have an Android platform per-se, the problem is if I don’t add it, if I then add it as a dependency for a mpp project that has also Android, it won’t automatically add the jvm dependency to the Android project, at the end not compiling at all

I have a question/issue with the new native memory manager. In the old implementation and with Swift native memory management (reference counting) if an object is never used in any thread but the main thread it will also be deallocated in the main thread. With the new memory manager this does not seem to be the case because the garbage collector runs in a separate thread and it causes issues for custom implementations of deinit which require the code to be executed on the main thread (such as UIView/UIViewController instances). What is the best practice in this regard?

Any change to add GoLang support? I know it is used for server. It would be nice to share business logic between server and client

Hey guys, i have a question, how do we handle Either response in iOS for KMM Like if it's Either< Type_A , Type_B > How do i get the values of Type_A and Type_B ?

I am trying to grasp and explain the difference between platform and target. Is this correct?

Kotlin/JVM, Kotlin/JS and Kotlin/Native are three technologies used to compile Kotlin code into different platforms. For instance, Kotlin/JVM can be used to compile Kotlin code for Android or for purely JVM platform, and Kotlin/Native can be used to compile Kotlin code for iOS, watchOS or Android NDK platform. For many of those platforms, there are multiple targets, like when we compile with Kotlin/Native to iOS platform, we can Apple iOS on ARM64 or Apple iOS simulator on x86_64.

I'm trying to understand what the repercussions of

w: duplicate library name

warnings are. I recently upgraded one of the libraries (Turbine) to the latest version. It was previous using

1.6.1

coroutine version, but the latest version upgraded coroutines to

1.6.4

. Our app is using

1.6.3

version and only after upgrading the Turbine library did we start seeing the duplicate library warning. Did this start happening because Turbine is using a later version of the coroutines library? With the

-Werror

flag set, compilation started failing and I'm trying to understand if I should be looking for a way to suppress this warning or will that come back to bite us in the future?

I want to implement a food delivery KMM app. What I can use for geospatial/geolocation data for my KMM project ( android/swiftui) that will work for both?

I will want to check if the customer location(lat long) is inside a polygon(area)

Can google places be shared in KMM (swiftui and kotlin)? Just google places, not google maps

how can I use

value class

in a multiplatform project? Previously I used

inline class

but I see it’s deprecated now. Using

value class

produces an error “Value classes without @JvmInline annotation are not supported yet” and I cannot use

@JvmInline

in a multiplatform project obviously. What’s the recommended path forward? Keep using

inline class

? What’s the plan of proper multiplatform support for

value class

? Once we clarify all of it, I’ll propose some changes to the docs: https://kotlinlang.org/docs/inline-classes.html

Did anybody encounter problems when using the published repository in common code? Platform-specific published code seems to work (-jvm, -js etc) but the common module seems to be empty. Everything seems to be fine when using the code inside the project (with implementation(project(":utils")) ). I am using this build file:

Hello. We are working on an iOS app that has multiple extensions, (Notification, Notification Content, Widget). I’m trying to use the “shared” framework in each of them and have not been successful. At first I added the

:shared:embedAndSignAppleFrameworkForXcode

to the Run Script for the widget. Then I manually had to remove the framework in the extension, otherwise TestFlight wouldn’t accept the binary. I then went to do the same for the next extension, and started getting sporadic build success and failures. I’m guessing Xcode is compiling multiple things at the same time which might be causing issues? I decided to switch to CocoaPods route thinking I’d get the one framework I could easily add to each of the targets. Again, this worked for one extension, and then sporadic build success and failures with multiple extensions. Is there any examples out there for best practice when sharing KMM between multiple targets? UPDATE: worked on this all day, and in my CI, turns out I needed to run

./gradlew podInstall

first before doing anything vs manually doing

pod install

I’m using

native.cocoapods

plugin and I try to configure it in a way that

publish

task would create a

.podspec

file and

.xcframework

in given hierarchy:

- buildDir/
  - File.podspec
  - frameworks/
    - framework.xcframework

Does anyone have an idea how to achieve that? Looking at

cocoapods

DSL and cannot find anything

Hi all Is there any way to modularize a KMM project? I want to follow the clean architecture so in the bussiness layer I want to have 2 KMM modules. One for the data layer and the other one for the domain layer

Hello. I am trying to use FCM in my KMM app. Does anyone know how I can do it in the shared module? Thanks 🙂

I am doing this because its the only way that I know I can send push notifications when my KMM app its closed

Is there any solution to

expect

a function with different returns types in the actual implementations? I have

suspend fun makeRequest(): Unit

for my native target, but Kotlin doesn’t allow to apply

@JsExport

due to the suspend keyword so I’ve created

fun makeRequest(): Promise<Unit>

for the JS target. However, due to the different return types I can’t find any way to

expect

in my common code the

makeRequest

function. Is there any workaround?

Hi all, I want to create and publish a multiplatform library, just like the tutorial https://kotlinlang.org/docs/multiplatform-library.html , but I have some objc native code and a static framework dependency. I managed to build my KMP project into a dynamic framework which could work on iOS Xcode project directly, but how could I make it available by another KMP project and make them all useable in iOS Xcode project (of course I need to publish my library into maven local or maven central)?

I'm trying to add a cocoapod dependency to my project, but the

import cocoapods.*

package does not become available. If I remove the import directive the project builds find and I also see the cocoapod files in the build folder.

cocoapods {
        summary = "CocoaPods test library"
        homepage = "<https://github.com/JetBrains/kotlin>"
        version = "1.0"
        ios.deploymentTarget = "14.1"
        pod("AFNetworking") {
            version = "~> 4.0.1"
        }
    }

That's my setup, but I can't import

import cocoapods.AFNetworking.*
