Has anyone resolved the

The code signature version is no longer supported.

when installing on a real iOS device? The app runs on the simulator fine and I've followed all of the steps here: https://kotlinlang.org/docs/multiplatform-mobile-understand-project-structure.html#ios-application I'm just sharing a KMM module locally using

embedAndSignAppleFrameworkForXcode

in the build phases and when I remove that build phase it will install fine on a real device. I see there is a way to share the code via cocoapods and using the

path

to set it. But I'm trying to avoid using cocoapods on iOS.

Hi All! I've got a KMM question you might have experienced before... Basically we are building a KMM Lib that depends on a Pod (it's tensorflow) but when we import the exported SwiftPackage to the Demo app it doesn't seem to be including the pod in the dependencies. Do you know if there is a way of exporting the pod with the XCFramework file? I'm kinda stumped and can't see anything on the channels. This is what I have in the Gradle build file

iosArm64 {
    binaries {
        framework {
            isStatic = true
            transitiveExport = true
        }
    }
}

cocoapods {
    summary = Metadata.IOS.summary
    homepage = Metadata.IOS.homepage
    version = Metadata.IOS.sdkVersion
    ios.deploymentTarget = Metadata.IOS.deploymentTarget
    framework {
        baseName = Metadata.IOS.frameworkBaseName
        isStatic = true
        transitiveExport = true
    }
    pod("TensorFlowLiteTaskVision")
}

Basically when we use it we get this error in XCode

Undefined symbol: _OBJC_CLASS_$_GMLImage

which is part of the Tensorflow pod...

Hello! Is varargs unsupported in kmm?

Best way to call 2 suspended Kotlin methods on swiftUI

Currently I am calling them this way, but it creates somehow 2 different sessions whenever call the second method:

func checkIfUser()
  {
    Task{
          do{
                try await self.repo.getUserProfile().watch() {items in//first method
                    self.myUser = items as! UserInfo
           
                 repo.insertFCMWhenLogin(token: myFCMToken!){error in//second method
                                                             }

As someone who was using AppCode to build multiplatform macOS projects, I'm very sad that I'll have to go back to Xcode 😔. https://blog.jetbrains.com/appcode/2022/12/appcode-2022-3-release-and-end-of-sales-and-support/

Hey Everyone. This is Zeeshan Syed. I'm an Android App Developer working with Genfare SPX. We have a requirement to unify the Point of Sale features. Our goal is to club a web, Windows application and Android app (each one has many similar functionality). These 3 platforms' main functionality is to read and write smart cards using a USB card encoder (we have more devices like a customer pole display, credit card swiping machine, etc). Since we have 3 different platforms to handle individually, we had to do a lot of effort making changes in each platform. That's why we want to build a unified Kotlin Multi-platform project. I have no clear way of planning and I don't know whether it is possible to do or not. Because, each platform (Windows and Android) heavily depends on platform specific code as we have to access peripheral devices connected to USB. If you have any suggestions on how to achieve this or if you want more info, please ask. Your suggestions will help us tremendously.

KMM folks, Is there a KMM lib which can be use to perform cryptographic ops similar to what java.security does? Usecase is to generate key pairs using algorithms like EC

Hi all. I am doing a project in Jetpack Compose Multiplatform. I need to implement google sign in on Android and iOS. Are there any libraries, any ideas how I can organize expect/actual interface for each platform?

Hello everyone, I’m trying to make common Firebase Analytics and Crashlytics implementations for android and IOS. But I’m just facing a problem adding Firebase dependencies, I’m getting the error:

Project already has a CocoaPods dependency with the name FirebaseCrashlytics

. Any idea how to solve this?

kotlin {
    android()
    ios()

    cocoapods {
        summary = "This module contains implementation of analytics and crashlytics"
        ios.deploymentTarget = "15.0"
        version = "1.10.2"
        framework {
            baseName = "monitoring"
               pod("FirebaseCrashlytics")
            // pod("FirebaseAnalytics")
        }
    }
}

I have updated my

parcelize-darwin

compiler plugin, that I created a couple of years ago. And published the first version. https://twitter.com/arkann1985/status/1603702344658685953 Basically it adds Parcelable and Parcelize support for all Darwin targets. Experimental. Together with expect/actual it makes it possible to use Parcelize in commonMain.

Hi everyone, is there any good kmm library for QR code scanning?

Can I typeAlias a class with expect and then add extension functions to it in the respective platform portions? I've tried it with the bare "expect class" statement in common and then adding extension functions in the platform code, but I'm then finding the rest of the code doesn't find the extension functions. It doesn't seem to matter if I extend the typeAlias or the original class. Is it doable?

Hi there, I have created a KMP library implementing ktor, but when I install this library in a project personal, I get the following message:

, can you help me please?

For some reason, the “ios” target disappeared from my unit test gutter icon menus. Any idea why that would happen? I can still run

gradle iosX64Test

and it works correctly though

Out of curiosity, why is

MPP

used as the shorthand for multiplatform?

Hello people, is there a way to have special characters, in tests, in a KMP module with an Android variant? I have a module with various Unit Tests with backticks names ``like this`` , and after adding

android()

variant, I cannot build because of

com.android.tools.r8.internal.Jc: Space characters in SimpleName ‘handles ConnectException’ are not allowed prior to DEX version 040

This seems a bit awkward as Jvm Android modules can contain tests with backticks ( except instrumented tests ) Is there a solution/workaround? I could disable test

androidTest

if that would solve it ( how? ) as 99% of the code in the main source set

Hello, every one! I am a new comer on KMM. I just followed the KMM getting started tutorial and chose Android Studio as my IDE. But as the picture shown, I faced a problem that i cannot jump to the swift UI definition in Android Studio and the code highlight and smart tip are not so good. In Xcode, the same code project behaves well. I learned from StackOverflow: Syntax highlighting not working for iosApp and they told me I should use XCode or AppCode. Is there any other way to code in the same IDE? Otherwise it may bring a bad developing experience. Anybody can share me some advices and offer some help? Thanks~

I was thinking of way to share localised strings across platforms. On android, we use strings.xml which allows you to use them in both compose & xml layouts. Just curious what would happen if we replace them with kotlin objects instead. It’s a challenge for xml layouts, but for compose, you can totally use it. Moreover, we can build a shared library which will give you statically typed accessors for each key, across android, iOS and web. Has anyone tried something similar already?

What does this mean for the future of KMM? https://www.swift.org/blog/future-of-foundation/ As I understand it, K/N binds to Obj-C, not Swift, which allows it to access the iOS Foundation classes as Obj-C classes. If the Foundation is rewritten in Swift, that goes away, doesn't it? It seems to me that sooner or later, K/N will have to be bound directly to Swift for KMM to have a future, won't it? I haven't seen anything lately about Kotlin/Swift interop on the roadmap. Is JetBrains still working on that? I've really come to like KMM, and I'd hate to see Apple pull the rug out from under it.

Today I tried kotlin react well kind of wanted to do something , with react and typescript and it didn't work Writing react ui in kotlin is very hard , I am very used to tsx and the interoperability between kotlin and typescript is pretty less , I mean expect it to work like java and kotlin Kotlin to Typescript Interoperability I would write code in typescript file or tsx for react components to be written inside typescript and then I would call the typescript react functions inside kotlin react , or be able to call kotlin functions inside typescript and kotlin compiler would handle the compilation of both to javascript , I don't know how this can be achieved but this would be ideal. Typescript can be like java just giving my opinion on what I expect would happen iin an ideal environment

Having some issues with my multiplatform project, trying to run the JVM main function in IntelliJ runs compileJava, but that seems to error, listing only the Android compileJava tasks:

Cannot locate tasks that match ':ac-frontend:compileJava' as task 'compileJava' is ambiguous in project ':ac-frontend'. Candidates are: 'compileDebugAndroidTestJavaWithJavac', 'compileDebugJavaWithJavac', 'compileDebugUnitTestJavaWithJavac', 'compileReleaseJavaWithJavac', 'compileReleaseUnitTestJavaWithJavac'.

If I add

withJava

to my

kotlin { jvm { ... }}

configuration, it complains it conflicts with the Android plugin. What do I do in this situation?

In Gradle, if I wanted to iterate over all the dependencies in a multiplatform project for a specific platform, how would I do that?

Suspension functions can be called only within coroutine body for the code doing a remove and after a logout:

suspend fun doLogout(token: String) {
    val userId = appService.currentUser?.id

        realm.write {

            var user = query<UserInfo>("_id = $0", userId).first().find()
            if (user != null) {
                val productIndex =
                    user.FCMToken.withIndex().findLast { it.value == token }!!.index

                user = findLatest(user)!!.also {
                    it.FCMToken.removeAt(productIndex)
                }
                copyToRealm(user)

                appService.currentUser?.logOut() // Suspension functions can be called only within coroutine body

            }
        }
}

Is there anyway to fix this without changing much code? I need to do first the db operation then logOut()
