Crash on iOS with specific navigationCompose version (2.8.0-alpha09)

[MrJohn10]

When showing paywall on iOS with org.jetbrains.androidx.navigation:navigation-compose:2.8.0-alpha09 the app crashes.

Uncaught Kotlin exception: kotlin.native.internal.IrLinkageError: Function 'UIKitViewController' can not be called: No function found for symbol 'androidx.compose.ui.interop/UIKitViewController|UIKitViewController(kotlin.Function0<0:0>;androidx.compose.ui.Modifier;kotlin.Function1<0:0,kotlin.Unit>?;androidx.compose.ui.graphics.Color;kotlin.Function1<0:0,kotlin.Unit>?;kotlin.Function2<0:0,kotlinx.cinterop.CValue<platform.CoreGraphics.CGRect>,kotlin.Unit>?;kotlin.Boolean;androidx.compose.runtime.Composer?;kotlin.Int;kotlin.Int){0§<platform.UIKit.UIViewController>}[0]'

code to open paywall:

val options = remember { PaywallOptions.Builder { }.build() }
Paywall(options)

purchases versions:
purchases-kmp = "1.0.0+13.2.0"
purchases-common = "13.2.0"

Changing navigationCompose version to "2.7.0-alpha07" fixes the issue.

Thanks for reporting! Looks to be similar to #201. Which version of Compose Multiplatform are you using? And which version of Kotlin?

[MrJohn10]

compose-plugin = "1.6.11"
kotlin = "2.0.0"

[JayShortway]

Thanks, I think this is the same issue as #201, not just related. Compose Navigation 2.8.0-alpha09 depends on Compose 1.7.0, whereas 2.7.0-alpha07 depends on Compose 1.6.10.

There seems to be a binary incompatibility between Compose 1.6.x and 1.7.0. As soon as 1.7.0 is stable, we should be able to support it and fix this issue.
