Body: Hello, I am facing a challenging issue with my SwiftUI iOS application, which is designed to work on an iPad and connect to an external display. The app, called "EasyJoin," is intended to provide a single-touch interface for joining conference meetings. It pulls events from a calendar and provides a "Join" button to connect to the meeting. The Goal: Mirror the app on an external display in its native aspect ratio. Also mirror any other client applications launched from EasyJoin (such as Google Meet, Teams, WebEx, Zoom) to the external display in its native aspect ratio. The Issue: While I have been successful in displaying the app on the external display, the iPad screen goes black as soon as the external display is connected. I need both the iPad and the external display to show the app simultaneously, each in their native aspect ratios. What I've Tried: Created separate UIWindow objects for the internal and external displays. Used NotificationCenter to listen for UIScreen.didConnectNotification and UIScreen.didDisconnectNotification. Tried managing windows through both AppDelegate and SceneDelegate. Explicitly set windowLevel for both internal and external windows. Despite these efforts, the issue persists. The external display works as expected, but the iPad screen remains black. Here is a snippet of my SceneDelegate.swift: // ... (Code for setting up UIWindow and listening for screen connect/disconnect) @objc func screenDidConnect(notification: Notification) { // ... (Code for setting up external UIWindow) externalWindow?.isHidden = false } @objc func screenDidDisconnect(notification: Notification) { externalWindow?.isHidden = true externalWindow = nil } I would appreciate any guidance or suggestions to resolve this issue. Thank you! Feel free to copy and paste this into a new post on the Apple Developer Forums. Hopefully, you'll get some specialized assistance that can help resolve the issue.
