Submitted bug with overlapping text field by dropdown menu and ignoring ime padding on iOS https://youtrack.jetbrains.com/issue/CMP-8574 Has anyone encountered this problem in their app? Have you found the temporary solution?

It seems that

imePadding

lags behind the iOS keyboard, is there some preferred way of syncing with the keyboard or does this need to happen outside of Compose?

Hi, I'm trying to analyse the .framework file size for the release variant of the iOS app. I can see that the size is big when I run iOS in the release configuration. I tried a few well know apps like KotlinConf app and I can see the shared.framework binary file is around 200MB locally. However, the app size on app store is much smaller. What is the right way to analyse the size?

Is there any plugin of some sort to show the physical attached ios devices in Android Studio just like we have for Android Devices? I am running Narwhal Canary 9

Hey Folks 👋 I'm checking if we have

SavedStateHandle

support for

ViewModel

in iOS, or is it yet limited to Android side?

Uncaught Kotlin exception: kotlin.IllegalStateException: Currently, UIKitViewController cannot be used within Popups or Dialogs

hi is this available to use? if so in which version?

Hiding the status bar when a specific native UIViewController is being shown with

UIKitViewController

Compose call? I have tried a few things:

UIApplication.sharedApplication.setStatusBarHidden(true, UIStatusBarAnimation.UIStatusBarAnimationNone)

but this is deprecated in iOS 10 (9 years ago) and has problems that if the app is closed/crashed in between the call with

true

and

false

the next time the app is started the status bar is still hidden... Then I found out that the

ComposeUIViewControllerConfiguration

has a delegate that can help control this a bit better, but that delegate is also deprecated now with a suggestion to create a parent

UIViewController

around the Compose Host UIViewController, so I tried the following but this causes issues with the sizing of the entire Compose hierarchy (basically seems to assume the initial viewport never changes regardless of rotations and other updates). How to fix this? Is there some additional methods to override in the

UIViewController

wrapper that will fix it? Thanks!

class MainViewControllerWrapper(val vc: UIViewController): UIViewController(null, null) {
    @OptIn(ExperimentalForeignApi::class)
    override fun loadView() {
        super.loadView()
        vc.willMoveToParentViewController(this)
        vc.view.setFrame(view.frame)
        view.addSubview(vc.view)
        addChildViewController(vc)
        vc.didMoveToParentViewController(this)
    }

    override fun prefersStatusBarHidden() = anyPrefersStatusBarHidden()
    companion object {
        fun UIViewController.anyPrefersStatusBarHidden(): Boolean =
            childViewControllers.any { (it as? UIViewController)?.anyPrefersStatusBarHidden() == true }
    }
}

Hi all, maybe I have some more luck here 🙏

Reheating the iOS Accessibility topic. By default, neither

OutlinedTextField

nor

TextField

sets up additional accessibility info such as label or any additional info like placeholder value or supportingText, on iOS. Meanwhile on Android these are handled well. Is there something I miss, or is it intentionally so minimally supported on other platforms?

Hi, I need to check when my app is destroyed (totally closed) in iOS. I look at the docs and I found the mapping between Android and iOS around LifeCycle. But viewControllerDidLeaveWindowHierarchy is actually not available in the iOS docs and ON_DESTROY isn't called in an iOS app. Is this a bug or is it intended?

Is there any other way to access observeValueForKeyPath other than following the below process: https://proandroiddev.com/leveraging-key-value-observing-kvo-in-kotlin-multiplatform-kmp-for-ios-231519e5c1ff

Hello, Has anyone worked with AVPlayer? - I'm trying to get the

What icons library or approach do you use in Compose Multiplatform? Currently, I am using compose-icons but the icons look quite ugly

Hi everyone, I'm currently working on implementing Picture-in-Picture (PiP) functionality for a video player in a Kotlin Multiplatform (KMP) project. Specifically, I'm looking to: • Enable PiP when the user presses the home button • Support automatic PiP activation • Maintain compatibility with iOS/Android through KMP If anyone has experience with this or can recommend any helpful articles, tutorials, or blog posts on implementing PiP in KMP, I would greatly appreciate your suggestions. for IOS I am looking android i have created

I'm running into an issue on iOS with Koin & compose-navigation where

collectAsStateWithLifecycle

stops getting new values after restoring a view model after navigation. However, collecting without lifecycle does keep updating

@Composable
fun MyScreen(viewModel: MyViewModel = koinViewModel()) {
    val scope = rememberCoroutineScope()
    // collectLatest: Does Update
    scope.launch {
        viewModel.uiState.collectLatest { state -> println("collectLatest Id: ${state.id}") }
    }

    // collectAsState: Does Update
    val uiState by viewModel.uiState.collectAsState()
    Text("collectAsState Id: ${uiState.id}: ")

    // collectAsStateWithLifecycle: Does NOT Update
    val uiStateWithLifecycle by viewModel.uiState.collectAsStateWithLifecycle()
    Text("collectAsStateWithLifecycle Id: ${uiStateWithLifecycle.id}: ")
}

Any ideas on where I should go looking for a fix?

Hi everyone, have any of you experienced a high delay when throwing an exception using compose multiplatform on iOS target?

Trying to update to Compose 1.9.0 and CMP 1.9.0-beta03, and having an issue building for iOS. It appears to me that the lifecycle-viewmodel-savedstate has not been built for iOS. See here: https://central.sonatype.com/search?q=lifecycle-viewmodel-savedstate most packages have the version of 2.9.2 , but the ios bits are 2.9.0-alpha6. And it will not build on iOS. Building with Kotlin 2.2.10. Thank you.

Hey, so i'm using the swift tabview within my cmp app, at the moment its not showing because i need to give it a fixed height, but how do i use the default tabview height and padding?

@Composable
actual fun PlatformBottomNavigation(
    selectedTabIndex: Int,
    onTabSelected: (Int) -> Unit,
    navigateToSettings: () -> Unit
) {
    val factory = LocalNativeViewFactory.current
    UIKitViewController(
        factory = {
            factory.createBottomNavigation(
                selectedTabIndex = selectedTabIndex,
                onTabSelected = onTabSelected,
                navigateToSettings = navigateToSettings
            )
        },
        modifier = Modifier
            .fillMaxWidth()
    )
}

Hello, using KMP Compose 1.8.2 I am having an issue with text fields. When I tap on a text field I get this error

Can't show file for stack frame : <DBGLLDBStackFrame: 0x149e1ea90> - stackNumber:0 - name:kfun:kotlin.coroutines.Continuation#<get-context>(){}kotlin.coroutines.CoroutineContext-trampoline. The file path does not exist on the file system: /opt/buildAgent/work/2d153abd4d2c0600/kotlin/libraries/stdlib/src/kotlin/coroutines/Continuation.kt

And the text field I am using

var textFieldValue by remember {
    mutableStateOf("")
}
                
OutlinedTextField(
    value = textFieldValue,
    onValueChange = { textFieldValue = it },
    singleLine = true,
    modifier = Modifier.width(160.dp)
)

And my imports

implementation(compose.runtime)
            implementation(compose.foundation)
            implementation(compose.material3)
            implementation(compose.ui)
            implementation(compose.components.resources)
            implementation(compose.components.uiToolingPreview)

Do you think I am missing something? Other UI elements work fine (buttons and checkboxes)

Hello everyone. In my team, we are having a big problem with

TextField

(and related) on iOS, it always crashes when we trying to click in it... The sample code:

@Composable
@Preview
fun App() {
    TextField(value = "Type", onValueChange = {})
}

The srceenshot of the app in the simulator and the crash We tested with compose 1.8.2, 1.8.1, and 1.8.0. For iOS: 18 and 17. EDIT: we are using the 2.9.1 version of the life cycle view mode compose lib, so the proposed fix proposed in thread of the post above doesn't work... The crash error message:

Hello everybody! Currently testing around in a CMP project. Im having trouble updating the state inside a swiftUI view.

@Composable
actual fun NativeButton(
    enabled: Boolean,
    onClick: () -> Unit,
    modifier: Modifier
) {
    val factory: NativeViewFactory = LocalNativeViewFactory.current

    UIKitViewController(
        modifier = modifier,
        factory = {
            factory.createNativeButton(
                enabled = enabled,
                onClick = onClick,
            )
        }
    )
}

Changing the enabled flag is not updating the UI in SwiftUI. How do i achieve this? Any suggestions? Thanks! 🙏

Hello, anyone tried to implement Google AdMob native app in ios using Compose Multiplatform? I've figured out how to load an ad's data, but it seem that I need a native view to handle user's click and that I can't simply use a Compose button's onClick callback. I suppose that I should go for a SwiftUI implementation, but before doing so I wanted to know if anyone had success implementing it in Compose 🙂 Thanks for reading and I wish you all a nice day!

Hello everyone! I'm starting a new KMP, and I was wandering if for modular architecture, the use of an "umbrella" KMP module was still the recommended way to expose the share code to ios, or if things had change and we can now export our KMP modules as independant XCFramework?

Compose navigation is really what lets iOS down when building a CMP app. I’m wondering whether I build out my navigation/coordinator flow natively by simply embedding each

ComposeUIViewController

in the

UINavigationController

However it seems @Kashismails has put together a working demo using Voyager. I wonder if anyone else is using a setup like this and in production? https://www.droidcon.com/2024/09/06/using-native-ios-navigation-from-compose-multiplatform/

After upgrading from Meerkat to Narwhal, we've noticed a change in how iOS run configurations are done. We are working in a monorepo with 3 apps, 2 of which are compose multiplatform. Even after setting the working directory to the app we actually want to run, it will always run the other. Obfuscated the names in the screenshot, but for example it would run app-1 instead:
