iOS devices cannot send UDP broadcasts

Steps to reproduce

1. Run the "Broadcast Sender Example" (https://doc.qt.io/qt-6/qtnetwork-broadcastsender-example.html ) on your development machine and the "Broadcast Receiver Example" (https://doc.qt.io/qt-6/qtnetwork-broadcastreceiver-example.html ) on your iOS device
2. Click "Start" on the sender
3. Repeat the test above after swapping Sender and Receiver machines

Outcomes

• macOS -> iOS works fine: The broadcast messages are received (expected)
• iOS -> macOS does not work: The broadcast messages are not received (not expected)

Notes

• My iOS Simulator (16.4) can send and receive broadcast messages without problems
• The real iOS device does ask for networking permission when we start broadcasting (see attached screenshot). But the broadcast seems to fail even after allowing it
