No class found for symbol 'kotlin.uuid/Uuid.Companion|null[0]'

[allansts]

Describe the bug When updating Koin from 4.0.0-RC1 to 4.0.0-RC2 when initialising the Koin in iOS this error happens:

Function doesn't have or inherit @Throws annotation and thus exception isn't propagated from Kotlin to Objective-C/Swift as NSError.
It is considered unexpected and unhandled instead. Program will be terminated.
Uncaught Kotlin exception: kotlin.native.internal.IrLinkageError: Can not get instance of singleton 'Companion': No class found for symbol 'kotlin.uuid/Uuid.Companion|null[0]'

To Reproduce Steps to reproduce the behavior:

1. Just try to initialise koin with iOS using the 4.0.0-RC2

Expected behavior Initialise normally as the previous version

Koin module and version: koin = "4.0.0-RC2"

koin-bom = { module = "io.insert-koin:koin-bom", version.ref = "koin" }
koin-compose = { module = "io.insert-koin:koin-compose", version.ref = "koin" }
koin-compose-viewmodel = { module = "io.insert-koin:koin-compose-viewmodel", version.ref = "koin" }
koin-compose-viewmodel-navigation = { module = "io.insert-koin:koin-compose-viewmodel-navigation", version.ref = "koin" }
koin-core = { module = "io.insert-koin:koin-core", version.ref = "koin" }

Snippet or Sample project to help reproduce Just follow the Koin KMP website sample: https://insert-koin.io/docs/reference/koin-mp/kmp

Same issue here. Might this has something to do, with the switch to kotlin UUID? https://github.com/InsertKoinIO/koin/compare/4.0.0-RC1...4.0.0-RC2#:~:text=import%20kotlin.uuid.ExperimentalUuidApi

[maksimpetrovskycorewill]

I'm facing the same issue.

[arnaudgiuliani]

You need Kotlin 2.0.20, as we are now using KMP UUid feature

[Elelan]

Facing same issue. KMP iOS not building after upgrading koin from 4.0.0-RC1 to 4.0.0-RC2. Kotlin version: 2.0.20 Ksp: 2.0.20-1.0.24

Showing The following message in xcode.

[arnaudgiuliani]

can you reproduce it easily?

[allansts]

can you reproduce it easily?

@arnaudgiuliani Yep, you can set up the Koin with KMP and use it on iOS. 100% reproducible at least when I tried it with Kotlin 2.0.0

[felix-leyva]

I tried it with Kotlin 2.0.20 and it worked correctly. It seems that it was indeed as you mentioned that the Kotlin UUID was not working with 2.0.0.

[arnaudgiuliani]

@allansts what Kotlin version do you have?

[allansts]

@allansts what Kotlin version do you have?

Kotlin 2.0.0, I will check it with Kotlin 2.0.20

Edited: I retest using Kotlin 2.0.20 and it is working fine so far. Thank you @arnaudgiuliani

Still reproducible for me. Android is working find. When building iOS only getting the error related to kotlin uuid. Could not find "com.benasher44:uuid" Kotlin 2.0.20 KSP 2.0.20-1.0.25 Koin 4.0.0-RC2

Weird 🤔 I can ping JB team about that. I will try to reproduce it 👍

[arnaudgiuliani]

I removed unused ref to com.benasher44:uuid. Now we are using Kotlin.uuid:

fun KoinPlatformTools.generateId() : String = Uuid.random().toString()

Look if you have a static reference to that kind of UUID object from previous com.benasher44:uuid - commit 23fcf1cbd4a025929f8b75ebad5d5c705bf0a9ba

I could run this on iOS and generate UUID. No problem.

Reopen if you see anything regarding this topic, in next releases 👍
