Hello! I just noticed that after updating to version 2.1.0-compose-experimental-alpha-07 from version 2.1.0-compose-experimental-alpha-06, the build time for iOS has increased several times. I have kotlin 1.9 in my project

[Pavel Shnyakin]

build time with alpha-07 ~5 minutes, with alpha-06 ~1 minute

[Arkadii Ivanov]

That's most likely due to Kotlin 1.9.0. I've seen multiple reports across this Slack.

[Arkadii Ivanov]

Or are seeing the difference by just updating Decompose, on the same Kotlin version?

[Pavel Shnyakin]

Just updating decompose

[Pavel Shnyakin]

Kotlin in project is 1.9 for both decompose versions

[Arkadii Ivanov]

Could you please share both build scans? Both with --no-build-cache and --rerun-tasks options.

[Pavel Shnyakin]

Yes, a little bit later

[Pavel Shnyakin]

just
./gradlew build --scan --no-build-cache --rerun-tasks ?

[Arkadii Ivanov]

Yes

[Pavel Shnyakin]

it fails 😡

:resources:compileCommonMainKotlinMetadata FAILED	
e: java.lang.IllegalStateException: e: Could not find "/Users/shpasha/StudioProjects/funts1/resources/build/kotlinTransformedMetadataLibraries/commonMain/org.jetbrains.kotlinx-atomicfu-0.17.3-nativeInterop-8G5yng.klib" in [/Users/shpasha/Library/Application Support/kotlin/daemon]

[Arkadii Ivanov]

Which command you were running when you noticed the difference?

[Pavel Shnyakin]

just ios build using KMM pluign

[Arkadii Ivanov]

There should be a Gradle task running. You can try running the same task with both versions of Decompose plus --scan --no-build-cache --rerun-tasks

[Arkadii Ivanov]

Or, if you could share a reproducer, that would be also helpful.

[Pavel Shnyakin]

i dont know what tasks are called, so i just try to call :composeApp:compileKotlinIosSimulatorArm64

[Pavel Shnyakin]

hope this is helpful

./gradlew :composeApp:compileKotlinIosSimulatorArm64 --scan --no-build-cache  --rerun-tasks

alpha-06
alpha-07

[Arkadii Ivanov]

Thanks! This looks pretty unexpected, I would say. Even :resources:compileKotlinIosSimulatorArm64 task which doesn't depend on Decompose takes 1.5x time.

I have noticed kotlin.native.cacheKind is set to none. Could you please try removing this property? It shouldn't be needed with Kotlin 1.9.0.
Also, it would be nice to have a reproducer project. Would it be possible to provide?

[Arkadii Ivanov]

Thanks for providing the reproducer privately. I had to disable cocoapods plugin in the project (because I don't have it installed), and somehow I don't see any difference between using Decompose version 2.1.0-compose-experimental-alpha-06 and 2.1.0-compose-experimental-alpha-07 .

The :composeApp:compileKotlinIosSimulatorArm64 --scan --no-build-cache --rerun-tasks command takes ~52 seconds on my machine for both versions. You can try disabling cocoapods just to check if it makes any difference. Otherwise it could be an issue with your environment. You can also try cleaning Gradle caches, as Kotlin update may confuse things.

[Pavel Shnyakin]

Thank you
Clearing all caches after the update really had a positive effect on the time of subsequent builds
