IrLinkageError for UIKitView after upgrading app to compose 1.7.0

[shtolik]

I've upgraded my app using you library to jetpack compose 1.7.0 but now i get this error when trying to start camera.

I think it's because of different versions of compose in use.
They've change UIKitView implementation and deprecated old. And I guess that leads to the error.

Uncaught Kotlin exception: kotlin.native.internal.IrLinkageError: Function 'UIKitView' can not be called: No function found for symbol 'androidx.compose.ui.interop/UIKitView|UIKitView(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.UIView>}[0]'

I'm facing a similar issue.

Same issue here.

I've found temporary solution.

Since compose multiplatform 1.7.0,
UIKitView and UIKitViewController in package androidx.compose.ui.interop are deprecated..

So we need to fix UIKitView code in PeekabooCamera.ios.kt like that.

import androidx.compose.ui.viewinterop.UIKitView
// import androidx.compose.ui.interop.UIKitView


UIKitView(
        modifier = modifier,
//      background = Color.Black,
        factory = {
            val dispatchGroup = dispatch_group_create()
            val cameraContainer = UIView()
            cameraContainer.backgroundColor = UIColor.blackColor // set background color
            cameraContainer.layer.addSublayer(cameraPreviewLayer)
            cameraPreviewLayer.videoGravity = AVLayerVideoGravityResizeAspectFill

            dispatch_group_enter(dispatchGroup)
            dispatch_async(queue) {
                captureSession.startRunning()
                dispatch_group_leave(dispatchGroup)
            }
            dispatch_group_notify(dispatchGroup, dispatch_get_main_queue()) {
                state.onCameraReady()
            }

            cameraContainer
        },
        update = { view ->
            cameraPreviewLayer.setFrame(view.bounds) // set frame of cameraPreviewLayer
        }
//      onResize = { view: UIView, rect: CValue<CGRect> ->
//          CATransaction.begin()
//          CATransaction.setValue(true, kCATransactionDisableActions)
//          view.layer.setFrame(rect)
//          cameraPreviewLayer.setFrame(rect)
//          CATransaction.commit()
//      },
    )

It works in Kotlin 2.0.10, but I haven't tested it enough so there may be some issues. Hope this helps and good luck!

For me this didnt work. we fixed this by moving the UIKitView() to a BoxWithConstraints and use the constraints for the size:

val rect = CGRectMake( 0.0, 0.0, maxWidth.toCGFloat(), maxHeight.toCGFloat(), ) cameraPreviewLayer.setFrame(rect)

@bevice1 Works for me too. Thanks

How to apply these fixes?

How to apply these fixes?

just clone the code of prrkaboo-ui and set it as a module in your project
