callAsFunction(value:sharingBehavior:)

Opens a window defined by a window group that presents the type of the specified value, using the specified sharingBehavior.

Declaration

@MainActor func callAsFunction<D>(value: D, sharingBehavior: OpenWindowAction.SharingBehavior) async throws where D : Decodable, D : Encodable, D : Hashable

Discussion

If sharingBehavior is requested or required, the window is shared if there is an available sharingSession and the person using your app confirms the offer to share. If sharingBehavior is requested and the window is not shared, it is opened normally. If sharingBehavior is required and the window is not shared, it is not opened, and an error is thrown. Regardless of sharingBehavior, an error is thrown if the window fails to open.

Don’t call this method directly. SwiftUI calls it when you call the openWindow action with a value:

try await openWindow(value: message.id,
sharingBehavior: .requested)
