I tried to find out what this means but couldnt find anything, so I ask here:

Cannot infer a bundle ID from packages of source files and exported dependencies, use the bundle name instead: ComposeApp. Please specify the bundle ID explicitly using the -Xbinary=bundleId=<id> compiler flag.

I get this from task > Task :composeApp:linkReleaseFrameworkIosArm64 FAILED in any sample project from kmp.jetbrains.com
What bundle id should be inserted where? In general I am very very confused by iOS compile errors, almost zero information everytime something fails. Maybe there is some debug flags I can add?

I see this as well but it doesn't stop my build. I mean my build continues and I can install and run the app just fine.

Yeah this is me trying hunt down every single warning I get (Going to treat all warnings as errors in gradle if I can soon) 🙂 It can compile as well, but differ between release vs debug builds, where I think some things will brick.
When I do clean rebuild I get errors and warnings, but it still says successful ... And next time doing incremental build it works. Very confusing :S

Tried follow https://youtrack.jetbrains.com/issue/KT-56152 but without luck.

Hello!
Here is documentation about BundleID:
https://www.jetbrains.com/help/kotlin-multiplatform-dev/multiplatform-publish-apps.html#bundle-id

[Joel Denke]

Thanks, I have the bundleId in my iosApp/Configuration/Config.xcconfig file but doesnt look like CMP respect it in newer 1.6.0-rc01+ versions, or fails parsing it, not sure.

Yeah, it doesn't automatically parse from iOS config files. You can use (as was mentioned above) the binaryOption function or if you're having trouble with the binaryOption(...) function:

binaries {
    compilerOptions.freeCompilerArgs.add("-Xbinary=bundleId=<your-bundle-id>")
}

Pay attention that this id should not be identical to your iOS application's bundle id, e.g. in my case the iOS application's bundle id is com.kenkoro.practice.ios, and the bundle id I provided as a compiler option is com.kenkoro.practice. Otherwise, you'll get the error on the image.

For a project reference, see this.
Hope it helps!
