Task sharedlinkDebugFrameworkIosX64 FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task 'sharedlinkDebugFrameworkIosX64'.

Compilation finished with errors

[Pablichjenkov]

Are all you Composable marked internal?
Are you using cocoapods or manually pulling the xcframework?

[SrSouza]

Just curios, there any different between cocoapods and xcframework when using Compose? 👀

[Pablichjenkov]

For some reason I tried to use compose-multiplatform with XC-Framework and started getting these type of build errors related to missing libskia.a symbols. Soon as I move to cocoapods the problems disappeared. All the official experimental examples use cocoapods for some reason.
But I couldn’t tell other than that practical experience. Hopefully someone maintainer could better explain why. There is no official documentation for compose-multiplatform yet. The Jetbrain documentation is meant for kotlin multiplatform without compose.

[Pablichjenkov]

Perhaps some of us should open an issue in the repo asking for an example that uses xcframework directly and not cocoapods. Perhaps one using SPM(swift package manager) too

[SrSouza]

xcframework is a requirement here for me 👀 We don’t use cocoapods.
@Dima Avdeev do you have any idea about this?

[Ahmad Hassan]

@Pablichjenkov
Yes, all composables are marked internal and using CocaPods

[Pablichjenkov]

Ok, do you remember the time or change where it started to happen?
Try downloading one of the templates from the experimental examples and move your code there.
Also make sure kdoctor confirms your environment is properly setup

[darkmoon_uk]

Please place long logs/source code in either a Slack Text Snippet or a code-block in a thread. Dumping them as regular text in the main channel is considered bad etiquette and will discourage replies. Just FYI.

[Dima Avdeev]

For now, we have some limitations for Compose on iOS:
• You can use a Compose library only as a static framework (in gradle isStatic=true)
https://github.com/JetBrains/compose-multiplatform-template/blob/aaa6a9f7b98d4d7cd8ec95112ebe2c455fa3f688/shared/build.gradle.kts#L27

• You should add kotlin.native.cacheKind=none https://github.com/JetBrains/compose-multiplatform-template/blob/aaa6a9f7b98d4d7cd8ec95112ebe2c455fa3f688/gradle.properties#L9
• You should use internal @Composable internal fun

[tylerwilson]

I ran into the same build error when building our XCFramework after adding the compose for iOS common libs. Setting the isStatic flag appears to have helped. Thank you!

[tylerwilson]

Now to figure out how to build it into my ios and macos targets, but not my watchos targets...

[Pablichjenkov]

Just don't add watchOs, don't add iOS as target but add targets directly like iOSArm64, iOSimulatorArm64 or so
