I don't know whether it matters, but the view is updated via a .task() modifier like follows: struct ContentView: View { var model: Model @State var pdf: PDFDocument? var body: some View { HStack { SheetView(pdf: pdf) ModelView(model: $model) .task(id: model) { pdf = await createPdf(from: model) } } } } func createPdf(from model: Model) async -> PDFDocument? { ... } where ModelView contains some controls for changing the model which triggers the task() modifier which creates a new PDFDocument and assigns it to the @State var pdf. All that works nicely with the only caveat that the update of the PDFView within the SheetView flashes. Thanks for any help! -Thorsten
