# mapItemDetailPopover(isPresented:item:displaysMap:attachmentAnchor:) Presents a map item detail popover. ``` @MainActor @preconcurrency func mapItemDetailPopover(isPresented: Binding, item: MKMapItem?, displaysMap: Bool = true, attachmentAnchor: PopoverAttachmentAnchor = .rect(.bounds)) -> some View ``` ## Parameters `isPresented` The binding to whether the detail sheet should be shown. `item` The map item to display. If nil, a “loading” view is displayed. `displaysMap` If an inline map should be displayed with the place data. A value of `true` must be specified if the application UI is not already showing the place in a map view. `attachmentAnchor` The positioning anchor that defines the attachment point of the popover. The default is `bounds`. ## Discussion Use this modifier if you want the system to choose the best orientation of the popover’s arrow. If you want to specify a particular edge for the arrow, use [`mapItemDetailPopover(isPresented:item:displaysMap:attachmentAnchor:arrowEdge:)`](/documentation/SwiftUI/View/mapItemDetailPopover(isPresented:item:displaysMap:attachmentAnchor:arrowEdge:)). --- Copyright © 2026 Apple Inc.
