Using a public property extensions with a @Composable backing delegate fails to link for iOS targets

[xxfast]

Describe the bug
I have property extensions with a @composable backing delegate that looks like this

val text: String @Composable get() = "Some text"

This works as expected for android/desktop, but fails to link for ios clients and throws this error

> Task :app:ui:linkPodDebugFrameworkIosSimulatorArm64

e: There is still an unbound symbol after generation of IR module <NyTimes>:

Unbound public symbol IrSimpleFunctionPublicSymbolImpl: io.github.xxfast.nytimes.ios.compose/text.<get-text>|8349765969627210272[0]

This could happen if there are two libraries, where one library was compiled against the different version of the other library than the one currently used in the project. Please check that the project configuration is correct and has consistent versions of dependencies.

Current work around is to keep these either private or internal

private val text: String @Composable get() = "Some text"
// or
private val text: String @Composable get() = "Some text"

Affected platforms
Select one of the platforms below:

• iOS

Versions

• Kotlin version*: 1.8.10
• Compose Multiplatform version*: 1.3.1
• OS version(s)*: iOS 16.2
• OS architecture (x86 or arm64): arm64

To Reproduce
Steps and/or the code snippet to reproduce the behavior:

1. Checkout xxfast/NYTimes-KMP@fc231fc
2. Open app/ios/ios.xcworkspace and run

Expected behavior
@Composable backing delegates for iOS targets to behave the same as other platforms.

This is similar to #2903 so feel free to close this or that if it is the same underlying issue

The fix is available with Compose Multiplatform 1.4.0 when used with kotlin 1.8.20
