Hey everyone. I'm trying to get the UI updated depending on a state change in SwiftUI using the

UIViewController

generated from the

ComposeUIViewController

function. I'm stuck trying to find a way to update the view controller (using a delegate/coordinator) but I can't find a way to create a custom

UIViewController

to pass the new state using the

updateNewUiupdateUIViewController

... Has anyone come across this? This would make me just rebuild everything in SwiftUI instead 😞

We have a sample with interop between SwiftUI and Compose. https://github.com/JetBrains/compose-multiplatform/tree/master/examples/chat In this sample, text field value passing from SwiftUI to Compose.

Hey @Dima Avdeev, thank you for your message. Unfortunately, your CustomComposeUIViewController has the same limitations as mine. I have a full screen in Compose which receives a state and action to behave and the action works great but passing the new state doesn't update the UI because the UIViewController is not set to be updated upon changes in any particular value. The

makeUIViewController

creates the view and the

updateUIViewController

updates it when there are changes, but yours is not implemented. It seems not possible to update it since it would need a delegate coordinator as a bridge and that would require a custom UIViewController.

Well, I think we need to create a sample with two side interop between SwiftUI and Compose
