Great. The current state will work if it's displayed at the same time. JetBrains/compose-multiplatform-core#1145 - will solve the situation in a more generic way. Closing as the original issue is already resolved |

## Proposed Changes Currently on both Desktop and iOS interop views are added to the view hierarchy in order to add nodes to Compose. It works only if all intersecting interop views were added at the same time (frame). So it's basically last-added - above-displayed. This PR changes this behavior in a way that it will respect the order inside Compose like regular compose elements. **It does NOT make any changes in the ability to display Compose content above interop view on Desktop**, this fix was made in #915 Main changes: - Unify a way to work with interop on Desktop (`SwingPanel`) and iOS (`UIKitView`) - `LocalInteropContainer` -> `LocalUIKitInteropContainer` on iOS - `LocalLayerContainer` -> `LocalSwingInteropContainer` on Desktop - Reduce copy-pasting by moving `OverlayLayout` and `EmptyLayout` - Remove overriding `add` method on `ComposePanel` and `ComposeWindowPanel` - it was required to redirect interop, but now it's not required and it's better to avoid changing default AWT hierarchy behaviour - Do not use `JLayeredPane`'s layers anymore - it brings a lot of transparency issues (faced with it on Windows too after unrelated change). Sorting via indexes is used instead - Add `InteropOrder` page to mpp demo ### How it works It utilizes `TraversableNode` to traverse the tree in the right order and calculate the index based on interop views count that placed before the current node in the hierarchy. All interop nodes are marked via `Modifier.trackSwingInterop`/`Modifier.trackUIKitInterop` modifier to filter them from the `LayoutNode`s tree. ## Testing Test: run reproducers from the issues or look at "InteropOrder" page in mpp demo Desktop | iOS --- | --- <img width="400" alt="Screenshot 2024-02-27 at 12 51 06" src="https://github.com/JetBrains/compose-multiplatform-core/assets/1836384/534cbdc8-9671-4ab7-bd6d-b577d2004d1b"> | <img width="300" alt="Simulator Screenshot - iPhone 15 Pro - 2024-02-27 at 12 49 50" src="https://github.com/JetBrains/compose-multiplatform-core/assets/1836384/ac7553db-c2a4-4c4a-a270-5d6dbf82fb79"> ## Issues Fixed ### Desktop Fixes JetBrains/compose-multiplatform#2926 Fixes JetBrains/compose-multiplatform#1521 (comment) ### iOS Fixes JetBrains/compose-multiplatform#4004 Fixes JetBrains/compose-multiplatform#3848

Describe the bug
UIKitViewis displayed on top of all other componentsAffected platforms
Versions
To Reproduce
Here is a
Composescreen for iOS.The screen is a stack of two boxes with video players inside them. Video players are implemented via
UIKitView.But the video player from the bottom box is displayed on top of all other components (See attached screenshot).
Expected behavior
The first video is not visible at all, because it is placed under the second video and the blue background.
Screenshots
Additional context
If I remove the top video, the bottom video will not be visible (correct behaviour).
