ComposeUIViewControllerDelegate viewDidDisappear and viewWillDisappear is never called

as per the doc it should work but it is not working https://www.jetbrains.com/help/kotlin-multiplatform-dev/compose-lifecycle.html#mapping-android-lifecycle-to-other-platforms

Hey guys, I would really appreciate if I could get your experience regarding performance while running Compose apps on iOS (jank is lag spikes /fps drops for those not familiar with the term) (Running in Release) 🔥 I've had no jank or fps issues 👀 There is some initial jank but after that it runs smoothly 🥶 Jank occurs occasionally 💤 I often find it difficult to reach the target frame rate of the device

Is it possible to import & reference dependencies added via SPM in

shared/src/iOSMain/kotlin

? I would like to add the UIKit view but I’m the JetBrains documentation only shows an example importing from platform package such as

platform.MapKit.MKMapView

or

platform.UIKit.UITextField

. I found an example importing a third-party library using Cocoapods but I wasn’t sure if this is a requirement of Compose Multiplatform or just a preference of the examples developer.

Reposting here to hear from iOS folks, as discrepancies between Android and iOS are the bulk of reported problems: https://kotlinlang.slack.com/archives/CJLTWPH7S/p1743758125868409

does anyone have a reference to the rules the CMP applies when converting semantic contentDescription to accessibility labels? Seen a instance where on iOS the content description removes the Text of a button and sets the contentDescription as the Buttons Label. I’d guess for my case I would want a way to send the accessibilityChild options from compose to swift so I can ignore this contentDescription for one particular item without goint down the expect actual root. Thanks.

I lost track but is there already a ticket for janky keyboard opening behavior? Especially when it pushes the content upwards. See video.

Is there a way to create a bitmap, that can be used to create ImageBitmap for compose? I have encoded barcode into intarray and want to create the image of it. It is fine on android, because I have mutable bitmap available, so I wonder if there's anything like this for iOS

Hey all 👋 We are working on E2E tests using Appium for a KMP app (Android/iOS) with Jetpack Compose UI. On Android, everything works fine — We can locate elements using

testTag

. But on iOS, Appium Inspector just shows a bunch of nested

XCUIElementTypeOther

elements — nothing is accessible via

accessibilityId

, XPATH, etc. We tried adding

Modifier.semantics { contentDescription = "..." }

alongside

testTag

, built the Compose framework with

./gradlew linkDebugFrameworkIosSimulatorArm64

, added it to Xcode (Embed & Sign), cleaned DerivedData, and rebuilt the app. Still, the elements aren’t exposed in Appium or Xcode Accessibility Inspector. Anyone got Compose-based elements discoverable on iOS for Appium? Are we missing something? Does anyone have an example of the repository where accessbility ID for iOS can be viewed using Appium Inspector? Attached screenshot of how the PoC app looks like in Appium Inspector for Android and iOS app.

Hello, will Compose for iOS go stable in Kotlin Conf 2025?👀 K

I'm using IntelliJ Ultimate, and to run my Compose app on iOS, I have to open Xcode and run it. Is there another way?

Hello Team I don't know if this is the right place to ask this. I have a string that is server driven, this string is an HTML text that has most of the html tags like, b/b,u/u,font color=#000000/font. How do I render this text using AnnotatedString ? I have tried this, but it only works for android, it doesn't work for iOS.

@Composable
fun annotatedString(text: String): AnnotatedString {
    return runCatching {
        AnnotatedString.fromHtml(text)
    }.getOrDefault(AnnotatedString(text))
}

here is an example of the string "font color='#DDDDDD'bCat/b/font and mouse are bfriends/b who loves uKotlin/u"

rebooting the device seems to temporarily fix it.

Pulling in CMP 1.8.0-rc01 and getting following when building iOS client. Anyone know what cause might be?

Hi everyone, I'm having a hard time to validate an email in a KMP/CMP project in the iOS target (Kotlin: 2.1.20 Compose: 1.8.0-rc01). I have different ways how to solve it for the other platforms (android, desktop, wasmJs), but I didn't found a way to make it work on iOS. At the moment I'm back to just Regex, but not even this simple code works, let alone everything the AI suggests using iOS classes from the foundation package, lol. When I just return 'true' everything works as expected. Any clue what I'm doing wrong or what could work?

private fun emailAddressRegex(value: String): Boolean {
    val emailRegex = Regex(
        // Very basic regex, without checking for edge case or i18n etc
        "[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\\.[A-Za-z]{2,}"
    )
    return value.matches(emailRegex)
}

I'm calling it from a BasicTextField using

snapshotFlow()

to update the state. Btw, the fix of the BasicSecureTextField works like a charm, thx!

Does anyone know if

enableTraceOSLog()

API (to enable iOS logging) can be called in any build type or it's intended to be used only in dev/debug/non-production builds?

Does anyone one know why some platform APIs are available under iosMain/ such as

platform.CoreLocation.CLLocation

but not APIs like

platform.*.NWPathMonitor

?

Hello, I’m working on. CMP with a iOS target Kotlin: 2.1.20, Compose: 1.8.0-rc01. I’m trying to include a swiftui component within the compose view, I’m following this medium article for implementation. https://cazimirroman.medium.com/mixing-swiftui-and-jetpack-compose-in-a-kotlin-multiplatform-project-for-ios-2f49a47085e7 now this works with these versioning. (see screenshot) what i currently get is a error when I try to view the screen with my native swiftUI controller.

Terminating app due to uncaught exception 'UIViewControllerHierarchyInconsistency', reason: 'child view controller:<_TtGC7SwiftUI19UIHostingControllerV12SharedApp13TextInputView_: 0x1008a0a00> should have parent view controller:(null) but actual parent is:<ComposeHostingViewController: 0x10122f860>'

So if this is the error, is it a case that I just need an empty UIViewController and add the newly hostedViewController to that? The other hidden context is that this is a bottomsheet

this steps take at least 5 min

is there any way to speed it up? or are there some new config need to be set?

I’m seeing in production some crashes for `invalidatePositionInWindow`: Does anybody know what the root cause for that is? Phone: iPhone SE

Hi there, I'm getting this animation flickering when expanding a CMP view inside a SwiftUI scroll view that looks like this:

ScrollView {
    VStack {
        cmpView1

        cmpView2

        swiftView1

        swiftView2

        // ...
    }
}

I'm using Compose 1.8.0-rc01, and this is how I'm creating the animation:

AnimatedVisibility(
    modifier = Modifier.fillMaxWidth(),
    visible = state.isVisible,
    enter = fadeIn(animationSpec = tween(durationMillis = 500)) + expandVertically(
        expandFrom = <http://Alignment.Top|Alignment.Top>,
        animationSpec = tween(durationMillis = 500)
    ),
    exit = fadeOut(animationSpec = tween(durationMillis = 500)) + shrinkVertically(
        shrinkTowards = <http://Alignment.Top|Alignment.Top>,
        animationSpec = tween(durationMillis = 500)
    )
) {
    // Banner
}

Any possible solutions to make it look nicer?

Am I reading this graph right? CMP outputs more fps than swiftui (i.e. better perf)…?

Hi there, I have a question regarding iOS during CMP development. The CMP version I'm using is

1.8.0

, and for multiplatform-navigation, it's

2.9.0-beta01

. The problem is that when using

androidx.compose.ui.window.Dialog

in

commonMain

, the dialog no longer appears after using features like an

in-app browser

or the

native camera

. Is there a way to solve this? this code working in cmp

1.7.3

, navigation

2.8.0-alpha10

Below is the test code:

NavHost(
    navController = navController,
    startDestination = startDestination,
) {
    composable(route = "home") {
        Home()
    }
}

@Composable
private fun Home() {
    var openDialog by remember { mutableStateOf(false) }

    Column(
        modifier = Modifier
            .systemBarsPadding()
            .fillMaxWidth(),
        horizontalAlignment = Alignment.CenterHorizontally
    ) {
        Text("Home")

        Button(
            onClick = { openDialog = true }
        ) {
            Text("Open Dialog")
        }

        Button(
            onClick = { PlatformInAppBrowserController.launch("<https://blog.jetbrains.com/kotlin/2025/05/compose-multiplatform-1-8-0-released-compose-multiplatform-for-ios-is-stable-and-production-ready/>") }
        ) {
            Text("Open inAppBrowser")
        }
    }

    if (openDialog) {
        Dialog(
            onDismissRequest = { openDialog = false },
            properties = DialogProperties(
                dismissOnBackPress = true,
                dismissOnClickOutside = true,
                usePlatformDefaultWidth = true
            )
        ) {
            Box(
                modifier = Modifier.fillMaxWidth()
                    .background(Color(0xFFFFFFFF))
                    .padding(40.dp)
            ) {
                Text(
                    text = "Home Dialog"
                )
            }
        }
    }
}

PlatformInAppBrowserController.ios.kt

:

actual object PlatformInAppBrowserController {

    private var lastPresentViewController: SFSafariViewController? = null

    private val rootViewController: UIViewController?
        get() = UIApplication.sharedApplication.keyWindow?.rootViewController

    actual fun launch(url: String) {
        val rootViewController = rootViewController ?: return
        val viewController = NSURL.URLWithString(url)?.let { nsUrl -> SFSafariViewController(nsUrl) } ?: return
        viewController.modalPresentationStyle = UIModalPresentationFullScreen
        lastPresentViewController = viewController

        rootViewController.presentViewController(
            viewControllerToPresent = viewController,
            animated = true,
            completion = {},
        )
    }
}

Now when iOS stable, is it now possible import Swift libraries like Apple Crypto? Or in general combine libraries directly between Kotlin, Swift and ObjC. Thats my main issue at the moment. Also stuff like Firebase.

Hey guys, I am trying to use a SwiftView on top of my Composable Screen, a SwiftUI Text() using

UIKitViewController

. However, it always seems to add a White background to it. I understand there’s a active issue for it but is there a workaround for it?

After updating to Compose 1.8.0, I'm seeing some Klib Resolver issues on `compileIosMainKotlinMetadata`:

Are there any workarounds?
