Just with Kotlin 1 8 0 Previous versions work Check that every function marked as Composable is internal Is a current limitation in the iOS target

1 No I just haven t tested older Kotlin verisons 2 2 I ll have a look at your advice

Michael Paus · Answer

Hmmm just checked with an other project of mine Not a single composable function is marked as internal but the whole project works like a charm on iOS Were did you hear about this limitation

Pablichjenkov · Answer

Here is the issue I am referring to <https github com JetBrains compose jb issues 2346|https github com JetBrains compose jb issues 2346> Now I believe that perhaps if you enclose the Composable in a class might work Also what sourceset are you using uiKitMain or iOS

I had this error once not on 1 8 0 but earlier I can t remember vividly have you done a total clean and rebuild

Michael Paus · Answer

I am not using the composable functions inside a class The project structure is derived from this example <https github com JetBrains compose jb tree master experimental examples falling balls mpp>

Michael Paus · Answer

< ayodele> I ll give that I try tomorrow

Pablichjenkov · Answer

Notice how the Composables or anything that exposes the Composable symbol is either internal or private Including Modifiers This is done for iOS to work Notice In shared iosMain the bindings exposed to swift objc are UIViewControllers not Composable As far as I am aware it is an existing issue

Michael Paus · Answer

I just verified that this problem is indeed related to this issue <https github com JetBrains compose jb issues 2346| 2346> The workaround is to make every composable function internal But that is a bit of a pain for the above code because it also uses composable lambdas as members in data structures and so all of these have to be made internal too and all functions which expose such data So for me this can only be a temporary workaround
