Actually, it seems like a basic route picker application also shows the issue. See example below: On a pre iOS 18.4 device, the user can successfully pick a route, on iOS 18.4, it spins forever. import SwiftUI import AVKit @main struct AirplayTestApp: App { var body: some Scene { WindowGroup { VStack { Text("Choose output device") DevicePickerView() } } } } struct DevicePickerView: UIViewRepresentable { func makeUIView(context: Context) -> UIView { let routePickerView = AVRoutePickerView() return routePickerView } func updateUIView(_ uiView: UIView, context: Context) {} }
