Attachment saving SwiftUI xcode warning

[agiguere]

SDK 25.8.0

I am using the AttachmentGroup with the operation CameraMenuItem

so far so good but Xcode complaint about this warning

\PurchaseOrderDetailsViewModel.attachmentUrls is isolated to the main actor. Accessing it via Binding from a different actor will cause undefined behaviors, and potential data races; This warning will become a runtime crash in a future version of SwiftUI.

I annotated my ViewModel property like so
@mainactor @published var attachmentUrls = URL

thanks
