👀 KMP Classes not visible in Swift by default 👀

Sometimes I face the issue that classes defined in KMP shared code are not visible in Swift.
I work around this issue by adding a “fake usage” to the MainViewController.kt class like below.
Afterwards I can access IOSPlatformFile in Swift code.

fun MainViewController() = ComposeUIViewController { App() }

// so swift code can access this
val platformFile: IOSPlatformFile = IOSPlatformFile("")

Could someone clarify what I’m doing wrong in these cases? Are only classes from the main module visible to Swift by default?

Hi,
Yes, only the main module (the one built in a iOS framework) is visible.
You can extend that by using export gradle keyword

For example: on my playground, I need to export some library, even some kotlin methods

Also, control what you put inside the bridge.
Too much (and useless) content inside is not good practise

Thanks @François for clarifying! That makes sense
