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

Undefined symbol: _kfun:androidx.compose.animation.core#androidx_compose_animation_core_MutableTransitionState$stableprop_getter$artificial(){}<http://kotlin.Int|kotlin.Int>

Undefined symbol: _kfun:androidx.compose.animation.core#androidx_compose_animation_core_TransitionState$stableprop_getter$artificial(){}<http://kotlin.Int|kotlin.Int>

[John O'Reilly]

looks like there's transitive dependency to following....

androidx.compose.animation:animation:1.7.2

[John O'Reilly]

(through androidx.navigation:navigation-compose:2.8.9)

[John O'Reilly]

updated nav dependency to 2.9.0-rc01 but get same issue

[Ekaterina Zaitseva]

Could you please try to use this dependency?

implementation("org.jetbrains.androidx.navigation:navigation-compose:2.9.0-alpha17")

[John O'Reilly]

still seeing same issue....maybe some other transitive dependency at play

[John O'Reilly]

trying in following branch fwiw https://github.com/joreilly/Confetti/tree/dependency_updates

[John O'Reilly]

btw if I run ./gradlew :shared:dependencies I'm getting following (though not seeing that in Xcode etc)

androidx.navigation:navigation-compose:2.9.0-alpha17 FAILED

[John O'Reilly]

looks like maybe later version of lifecycle dependency also needed....trying that now

[John O'Reilly]

same error

[Ekaterina Zaitseva]

Could you please add kotlin.native.cacheKind=none in gradle.properties
https://youtrack.jetbrains.com/issue/CMP-7571

[John O'Reilly]

that worked! (also updated that branch)

[robercoding]

I had a similar error:

Undefined symbol: _kfun:androidx.compose.animation.core#androidx_compose_animation_core_SeekableTransitionState$stableprop_getter$artificial(){}kotlin.Int

Undefined symbol: _kfun:androidx.compose.material3#androidx_compose_material3_ButtonDefaults$stableprop_getter$artificial(){}kotlin.Int

Undefined symbol: _kfun:androidx.compose.runtime#androidx_compose_runtime_ProvidedValue$stableprop_getter$artificial(){}kotlin.Int

That gradle property saved me a few hours of headaches (and life)!

Please note that disabling native caching really hurts build times, and you should only add this as a temporary workaround for the issue linked above.

For Confetti for example, we removed it soon after, here, by bumping the libraries that were causing a problem: https://github.com/joreilly/Confetti/pull/1611

If you look at your full build output, you should be able to see which library is causing the problem in your case.

[robercoding]

Thanks Márton, will do the investigation then
In fact that’s what I was noticing now, it took much more time to build than usual but helps to unblock the road.

[zsmb]

Here's an example of the kind of thing to look for in the build output, from the original Confetti problem's CI run. This appears earlier in the logs than the "Undefined symbol:" lines mentioned in the first message of this thread, and show that in that case, it was Decompose that the build was failing on.

Btw, since Compose for iOS is Beta, why breaking changes?

[robercoding]

I couldn’t find any issue mentioned earlier to the undefined symbol error.

But I have new undefined symbols errors after cleaning a bit the project and updating the same dependencies that you did on that Github PR

I suspect KMP Auth might be the issue although I cannot tell why, there may be some compose dependency conflicts since it uses 1.7.4 compose. (I’m using 1.8.0-rc01)

I’ll for now keep this kotlin.native.cacheKind=none property and keep an eye on any updates for the library.

It wasn't a change in Compose for iOS per se. As I understand it was a bug in the K1 compiler that's now fixed, and while there were patches added to bridge things over and for the new compiler to accept the older "incorrect" outputs, these patches don't work for the edge case where it's a transitive dependency and the library is taken from cache. Plus I believe release builds should be unaffected (as they don't use cache).

That's exactly the problem, that the uihelper module there depends on Compose runtime, and it's compiled against the older version.

@Mirzamehdi when you have the time, could you please ship a version of the library (even if pre-release) that uses 1.8.0-rc01?

[Mirzamehdi]

@robercoding I will bump the lib versions of KMPAuth asap and will make new release
