Modifier.pointerInput or clickable not working for UIKitView

[paxbun]

Describe the bug A clear and concise description of what the bug is.

Callbacks passed to AndroidView() via Modifier.pointerInput or Modifier.clickable are invoked, while callbacks passed to UIKitView() are not invoked.

Affected platforms

• iOS

Versions

• Kotlin version*: 1.9.23
• Compose Multiplatform version*: 1.6.10
• OS version(s)* (required for Desktop and iOS issues): iOS 17
• OS architecture (x86 or arm64): arm64
• Device (model or simulator for iOS issues): Both for real devices and simulators
• JDK (for desktop issues):

To Reproduce Steps and/or the code snippet to reproduce the behavior:

// MyView.kt
@Composable
expect fun MyView(modifier: Modifier)

// MyView.android.kt
@Composable
actual fun MyView(modifier: Modifier) {
  AndroidView(
    factory = {
      View(it).apply { background = ColorDrawable(Color.BLUE) }
    },
    modifier = modifier,
  )
}

// MyView.ios.kt
@Composable
actual fun MyView(modifier: Modifier) {
  UIKitView(
    factory = {
      UIView().apply { backgroundColor = UIColor.blueColor }
    },
    modifier = modifier,
  )
}

// App.kt
@Composable
fun App() {
  MyView(
    Modifier
      .fillMaxSize()
      .pointerInput(Unit) {
        detectTapGestures { offset -> println(offset) }
      }
  )
}

1. Observe a blue background is rendered.
2. Click anywhere.
3. On Android, logcat reports the xy coordinates of the touch position. On iOS, nothing is printed in stdout.

Expected behavior UIKitView should also handle touch events like AndroidView.

@paxbun You can try setting interactive = false

Hi @robxyy, where can I set that? I didn't notice that there is parameter interactive in UIKitView. This resolves my issue. Thanks for the comment!
