Interesting, having this build issue for my ios target. Haven't built on here in a while, but I don't think I changed anything very related to this recently.

[Adam Brown]

I've got it added as an api dep in both my common source set as well as my iosMain source set

[Adam Brown]

it looks like it's a problem with 2.0.0

[Arkadii Ivanov]

Interesting! Do you have source sets setup correctly? Also worth trying clean build with --no-build-cache argument. And, are there more logs?

[Arkadii Ivanov]

This looks like a possible solution! https://youtrack.jetbrains.com/issue/KT-45036/Native-Updating-ktor-to-1.5.1-breaks-transitiveExport-to-iOS#focus=Comments-27-4747136.0-0

Try updating Essenty to the same version used by your version of Decompose.

[Adam Brown]

oh interesting! let me look

[Adam Brown]

Kotlin 1.8.20

[Adam Brown]

ooo looks related to @Serializer maybe

[Arkadii Ivanov]

This one is different indeed. You need to update Decompose and Essenty to the latest versions.

hey not related, but is that a multiplatform RentrantLock you have in there? I'd love to have to exposed, heck even its own lib. Having to apply the atomicfu compiler plugin just to get that lock is a bit much

[Arkadii Ivanov]

I implemented Lock via expect/actual. On JVM it uses synchronized, on Darwin - NSReentrantLock
I don't need other native targets yet, but there is POSIX mutex in case you need it. https://github.com/arkivanov/Decompose/blob/master/decompose/src/commonMain/kotlin/com/arkivanov/decompose/Lock.kt
