We’re running into a strange issue in release iOS builds with the new memory model. Doesn’t happen in debug builds. When a user opens/closes a particular screen multiple times, on the ~12th try, we trigger the GC, and it crashes the app. The stracktrace looks something like:

Crashed: GC thread
0  QuizletSharedKotlin            0x919294 std::__1::invoke_result<kotlin::gc::ConcurrentMarkAndSweep::ConcurrentMarkAndSweep(kotlin::mm::ObjectFactory<kotlin::gc::ConcurrentMarkAndSweep>&, kotlin::gc::GCScheduler&)::$_2>::type kotlin::ScopedThread::Run<kotlin::gc::ConcurrentMarkAndSweep::ConcurrentMarkAndSweep(kotlin::mm::ObjectFactory<kotlin::gc::ConcurrentMarkAndSweep>&, kotlin::gc::GCScheduler&)::$_2>(kotlin::ScopedThread::attributes, kotlin::gc::ConcurrentMarkAndSweep::ConcurrentMarkAndSweep(kotlin::mm::ObjectFactory<kotlin::gc::ConcurrentMarkAndSweep>&, kotlin::gc::GCScheduler&)::$_2&&) + 1292

3  libsystem_pthread.dylib        0xe68 thread_start + 8

It’s super hard for us to create a minimal reproduction of this, but in case it’s relevant, we’ve been able to repro this with: • Kotlin 1.7.10 and 1.7.20-Beta • SqlDelight 1.5.3 and 2.0.0-alpha03 • kotlinx.coroutines 1.6.4 (without the

-native-mt

suffix) • KMP-NativeCoroutines 0.12.6-new-mm Any tips on how to narrow this down?

Is it possible to mix fragment and composable destination in a

NavHost

? I want to add a fragment that I don’t own, from a library, as a destination. I tried:

NavHost(
    navController = navController,
    startDestination = route,
) {
    composable(...) { ... )
    fragment<LibraryFragment>(id)
}

But when I run, the activity crashes with

Could not find Navigator with name "fragment". You must call NavController.addNavigator() for each navigation type.

If it’s not possible, is there another way to add a fragment to composition?

So I’m trying to use JS -> Kotlin. But every time I try and use a method the names are scrambled. I want to have

commonLib.myTestMap.get("key")

But the method available to me is

commonLib.myTestMap.get_11rb$("key")

Is there any way of having a standard getter for the keys in the map?

Hey all, small announcement 📣 : with the Jetpack Compose 1.8. beta01 release, you may notice that a significant number of APIs that were previously experimental, have been graduated to stable. 🫶 We care a lot about providing a high quality and cohesive API surface for Compose, while also adhering to strict binary compatibility across releases, to ensure upgrades are relatively straightforward. We’ve heard from the community that APIs that have been experimental for longer are harming the Compose experience, which is why we are decreasing our usage of experimental APIs moving forward. In 1.8, we will stabilize all experimental APIs in the Foundation and UI modules that have been unchanged for more than one full release cycle, and we plan to do the same for more modules in the future. As part of this effort, we have also identified APIs added in recent releases that are not what we believe we should commit to long term. This has led to the decision to deprecate the experimental
ContextualFlowRow
and
ContextualFlowColumn
, added in 1.7. It is possible for developers to implement their particular use cases, while we work on a plan for future components that can cover these functionalities better. The related APIs

FlowRow

and

FlowColumn

will become stable, however without the new
overflow
parameter added in the last release. Please reach out to us if you have any questions or concerns, thanks! gratitude thank you

Accompanist-Pager had a offScreenPageLimit parameter which was removed in v. 0.19.0. I want the same behaviour as Google Play store and only load the page when the user opens it. How can I set the offScreenLimit to 0 on my HorizontalPager?

I have a Maybe that then does a switchIfEmpty. The switchIfEmpty is still firing even though the value isn’t empty, anyone see anything like this? I am able to evaluate the Maybe by using blockingGet and can see that I’m getting my items. I should also mention that it’s a Flowable.firstElement to get that Maybe. Not sure if that’s relevant. I am using () instead of {} for the switchIfEmpty so parts of it are working
