How to use compose pagination with moko mvvm

Using livedata

I'm trying to understand what the best approach is to create a multiplaform app that runs on Android phone, Android Wear, iPhone and iWatch with a shared library. In my post from yesterday I was using Cocoapods for the shared library, but this gives me such a big headache, maybe I have to use XCFramework? I just tried to get it to work with an empty (new) Kotlin Multiplatform App project from Android Studio to get the "Hello, <<platform>>" demo running with the "Regular framework". It runs on the iPhone, but after adding the watchOS target in XCode, the problems start. I have uploaded the demo project to github: https://github.com/Chris-NL/Demo Building and running for iPhone works fine. Building for WatchOS works fine, but give me a warning: "linking against a dylib which is not safe for use in application extensions". When trying to run on the iWatch gives xCode gives me an installation error: "A signed resource has been added, modified, or deleted." I tried adding isStatic = true to build.gradle.kts, although that does remove the warning for watchOS, it results in installation errors on the iPhone. iMac (Retina 5K, 27-inch, Late 2015 with an 3,3 GHz Quad-Core Intel Core i5 running MacOS Montery 12.4) Android Studio Chipmunk xCode 13.4.1 all the latest plugins installed Anyone a clue on how to get this poperly to work?

I'm getting this error after calling a fun that returns a Promise:

Unhandled Runtime Error TypeError: hidden._get_entries__31877249_iz8n5_k$ is not a function

browser request is responding 200 Any idea? The fun in js target:

fun initialize (formId: String, hidden: Map<String, String>): Promise<InitializationResult> = GlobalScope.promise{ internalForm.initialize(formId, hidden)}

I have a KMM project that target Android, iOS and desktop JVM. Is there any way to easily share a small part of code between Android and JVM? It's just 20 lines of code, it doesn't look enough to create a new separate module just for this 😔

Hello 👋 I’m trying to develop a small POC to prove KMP is a good candidate to have our own shared library between Android and iOS. This library have to embed

WebRTC

compiled for each architecture. This is the first time for me with KMP, I am not sure about the good way to deal with my current issue. I built my shared library in KMP with embedded WebRTC for Android. It works like a charm. On iOS, I tried to create a

.xcFramework

with embedded WebRTC

xcFramework

. I can compile my iOS application with my own framework, and I can access to my library (like

WebRtcKt.initialize()

). But… I can’t access to WebRTC directly (like

RTCMTLVideoView

). 🤔 I tried several things, like transitive import, etc. but I didn’t find the good recipe ! 😂 If someone has any idea how to do that… 🙏

💬Results of the Kotlin Multiplatform Survey Q3-Q4 2021💬 Did you know that almost half (48%) of Kotlin Multiplatform developers use Android Studio with the Multiplatform Mobile Plugin installed? We asked backend, frontend, mobile, and full-stack developers about their experience with Kotlin Multiplatform. Check out the key highlights of our Q3–Q4 2021 user survey in this blog post!

Does anybody know of a sample project that uses AudioQueues for playing audio on iOS that was written using Kotlin in the iosMain portion of the shared module? I haven't seen any samples that do non-trivial iOS api calls with Kotlin yet.

Is it possible to achieve

@BeforeClass

behavior in Android/iOS common tests? kotlin.test has the annotation for Kotlin/Native, as does Junit for JVM. My naive attempt to typealias the two doesn't work on the JVM side.

Has anyone been able to get Cocoapods dependencies working on an M1 mac? From what I understand

cocoapods-generate

is needed to make it work, which requires a certain version of

cocoapods

which requires Ruby

2.6.0

which does not run on M1 macs.

I'm running into this issue trying to add

firebase-kotlin-sdk

and consume it in an iOS app. Getting the following error when I try to build iOS:

ld: framework not found FirebaseAuth

So I tried installing it via pods before running into all the pods issues mentioned above. Any workarounds would be greatly appreciated!

I’m using iOS cocoapods dependencies in my shared library.

pod("AFNetworking") {
            version = "~> 4.0.1"
        }
        pod("AgoraRtcEngine_iOS")

both libraries are available from https://cocoapods.org/ and working with another (standalone) iOS project. However,

cinteropAgoraRtcEngine_iOSIosArm64

was failed and I got

Exception in thread "main" java.lang.Error: /var/folders/3j/8k6z66l50dq_d1sjfxl8cphh0000gn/T/10429521223665112771.m:1:9: fatal error: module 'AgoraRtcEngine_iOS' not found

If I removed

pod("AgoraRtcEngine_iOS")

, it worked fine and I can

import cocoapods.AFNetworking.*

in iOS source-set Kotlin code. Any help are welcome!

I have a kmm module (

B

) that depends on another kmm module (

A

). However I also need to call

A

from my iOS app. I have a singleton in

A

that I initialise in my app and whose methods I call in

B

. Currently I get a not initialised exception in module B even though I have initialised my singleton in the app. Any Idea how I can fix this? Both the modules are in a single project and I am specifying their path in my podfile.

Can linuxMips32 and linuxMipsel32 be published with a macOS machine?

I have an existing project that we are hoping to switch to use KMP. We have a lot of complex swift code that we would like to include in the shared component. However, rewriting all of that Swift code would be time consuming. The Swift code does stuff like play buffered audio as it is streamed across the network. Is there a trick to reusing that Swift code easily? How have others migrated Swift code into a KMP world?

Hey! Bit of an in depth question, but I’m super interested in hearing what your approach is on this problem: I’m currently sharing all of my logic from the ViewModel upwards in KMM. So I’m using an actual/expect construct for the VM, where the android VM uses the jetpack viewmodel, and iOS uses a ‘default’ class. Then I’m using Koin for dependency injection, which works great on Android since there is a simple

viewModel

scope. But I’m running into problems on iOS with regards to the lifecycle.. Currently my VM is marked as a singleton for iOS, however there are a couple of problems that arise: • Initially I thought it would be a good idea to cancel the scope in the viewModel on viewDisappeared, but when I’m navigating back to that same screen Koin will provide the same VM with a cancelled coroutine scope, so that breaks stuff.. • Changing the viewModel to be a factory solves this problem, but then I can’t retain state across screen navigation, which isn’t the end of the world and I can make it work, but it seems like it’s limiting? It also introduces the problem of somehow having to manually save state like scroll positions What are your approaches to the lifecycle of viewmodels on iOS? When do you cancel the scope? Does the VM retain state across navigation?

Wouldn’t it be nice to be able to have the

AndroidManifest.xml

file of a “pure” Kotlin Multiplatform library generated or hidden or something? I have multiple modules which are pure Kotlin and only have code in

commonMain

sourceSet but they all have to have an

androidMain

folder with an almost empty

AndroidManifest.xml

file. Anybody else finding that annoying or I am just nitpicking?

like this? https://github.com/GradleUp/auto-manifest

Good morning guys, I’m resurrecting a 2yo Multiplatform Project + Android compose. I’m now on: • Kotlin 1.7 • AGP 7.2.1 • Compose 1.2.0-rc03 • Compose compiler 1.2.0 I’ve got some Multiplatform modules and surprisingly I didn’t need to change the Gradle setup

// something/build.gradle.kts
plugins {
    kotlin("multiplatform")
}

kotlin {
    jvm()

    sourceSets {
        val commonMain by getting {
            dependencies {
                implementation("blablabla")

Then I got an Android module

// client/android/build.gradle.kts
plugins {
    id("com.android.application")
    kotlin("android")
}

dependencies {
    implementation(project(":something")

My Gradle Sync succeeds, but in the Android module, all the dependencies from other modules are unresolved ( screen ) The IDE suggests me to add the dependency to the classpath, but the action adds a weird line, without any progress:

implementation(project(mapOf("path" to ":client")))

I've found that the IDE is throwing a bunch of errors for my androidTest source set, where it doesn't see any of my commonTest code. This includes `expect class`es and other types defined there. The tests compile and run without issue, but the IDE errors and lack of code completion are unhelpful. Is this a known issue or is anyone aware of a resolution? Android Studio Chipmunk 2021.2.1 Patch 1 AGP 7.2.1 Kotlin 1.7.0

I have tests in commonTest and would like to debug them in KotlinJs (nodejs). For whatever reasons, the break-points do not kick in. Any Ideas?

I've been working on using KMM in Flutter. The library, Klutter, is now available and I recently published a tutorial about it. I'm personally very excited about using KMM with Flutter! Would love to get some feedback because I've been working on it on my own. If you have ideas, improvements, etc, don't hesitate to message me! I would really appreciate it. https://medium.com/@jjgbuijs/flutter-battery-app-made-with-klutter-74d47002efb1

I have a hard time deciding how to manage my state in KMM. My database layer exposes flows. And I usually handle logic inside of Android ViewModels. Is there a goto approach in KMM?

Contrary to this blog post (which was very helpful and insightful), I'm finding that src/commonTest/resources are not available to Android unit or instrumented tests. Is this expected behavior? Even adding

kotlin {
  sourceSets {
    val androidTest by getting {
      resources.srcDir("src/commonTest/resources")
      ...

doesn't copy the resources from the common location for Android tests. Is there a good way to avoid duplicating these resource folders between source sets (hopefully other than a manual symlink)?

Update on KMM not working on arm64 simulator on M1 Macbook: I previously posted about having issues with KMM framework file generated by the Cocoapods gradle plugin working with the arm64 simulator target on iOS. After suggestions in this thread, I stopped using the cocoapods plugin and switched to XCFramework which included the arm64 simulator target. This did not work on the simulator. Instead, I was only able to get simulator with my KMM project working if I opened Xcode with Rosetta to run the x64 simulator target. If anyone has any suggestions on how to get the arm64 simulator target to work, let me know.

I am seeing KTIJ-19344 with latest stable and EAP AppCode, both with the latest KMM plugin. Has the fix not arrived on AppCode? I can not test on AS as I have x64 only dependencies in the App need a x64 ios simulator on Apple M1 which seems not supported with AS.

I am working on image processing with voize-gmbh/pytorch-lite-multiplatform But the dependency is not installed in the Kmm project. if we comment out the iosSimulatorArm64() then library is installed successfully. But in case of Xcode when we running the iosApp project the having linker issues. And if the iosSimulatorArm64() is uncommented again then we are not able to installed the library. And One more thing how to convert the Bitmap32 to UIIMage and vice-versa in KMM. and also In case of Android we are able to convert the Korim Bitmap into Android Bitmap. but how to convert android bitmap to Korim Bitmap. Thanks in advance.

Is there anywhere that I can go for more information about KMM releases? I am specifically curious at this time about the

native.cocoapods

plugin for the gradle file. I noticed a difference in the output of my podspec and I can't seem to find any information on this change on the web

Hi, we wanted to adopt KMM and I had my iOS colleague doing a spike by re-writing a lib of iOS in KMM. i turned out that there is a blocker for us to use and certain flaws: • no support for

Codable

in iOS: currently nearly all models of our native iOS app implement that protocol and therefore shared KMM models cannot be used in those models (unless you manually write (de)serialization for that shared objects - which is a blocker for us) - seems like a known issue - but i wonder why there is not much more noise around that. other issues he mentioned: • Operator overloads do not translate to Swift ◦ e.g. cannot overload operators such as

+

,

-

,

<

etc. (required for conformance to

Comparable

for example) • Cannot take advantage of other protocol conformances, e.g. inheriting from the protocol

Sequence

gives a huge amount of functionality such as

map

,

flatMap

,

forEach

etc. • Integers are all represented as

Int32

in Swift - annoying to do conversions to a regular

Int

everywhere • Cannot create non-final classes, meaning we cannot implement any class as

Codable

or

Strideable

(needed to allow us to loops over calendar dates in a calendar date range) • Unable to have “Swifty” function names as it’s not possible to remove parameter names, and parameter labels have to be the same as the parameter names. i.e. we cannot have a function like

func date(in timeZone: TimeZone) -> Date

would be great if someone can confirm this limitations or provide guidance on how to overcome those.
