# popover(isPresented:attachmentAnchor:arrowEdge:content:) Presents a popover when a given condition is true. ``` @export(implementation) nonisolated func popover(isPresented: Binding, attachmentAnchor: PopoverAttachmentAnchor = .rect(.bounds), arrowEdge: Edge? = nil, @ContentBuilder content: @escaping () -> Content) -> some View where Content : View ``` ## Parameters `isPresented` A binding to a Boolean value that determines whether to present the popover content that you return from the modifier’s `content` closure. `attachmentAnchor` The positioning anchor that defines the attachment point of the popover. The default is [`bounds`](/documentation/SwiftUI/Anchor/Source/bounds). `arrowEdge` The edge of the `attachmentAnchor` that defines the location of the popover’s arrow. The default is `nil`, which results in the system allowing any arrow edge. `content` A closure returning the content of the popover. ## Discussion Use this method to show a popover with contents that are a SwiftUI view, which you provide when a bound Boolean variable is `true`. In the example below, a popover displays whenever the user toggles the `isShowingPopover` state variable by pressing the “Show Popover” button: ```swift struct PopoverExample: View { @State private var isShowingPopover = false var body: some View { Button("Show Popover") { self.isShowingPopover = true } .popover(isPresented: $isShowingPopover) { Text("Popover Content") .padding() } } } ```  > Important: Prior to iOS 18.1, the popover arrow edge was not > respected. Apps that are re-compiled with the iOS 18.1 or later SDK or > visionOS 2.1 or later SDK and run on iOS 18.1 or later or visionOS 2.1 > or later have the arrow edge respected. On macOS, arrow edge has always > been respected. Alternatively, to allow the system to choose the > best orientation of the popover’s arrow, use the > ``View/popover(isPresented:attachmentAnchor:content:)`` variant. On iPhone, popovers adapt into sheets. In vertically compact environments, such as iPhone in landscape orientation, a popover presentation automatically adapts to appear as a full-screen cover. Use the [`presentationCompactAdaptation(_:)`](/documentation/SwiftUI/View/presentationCompactAdaptation(_:)) or [`presentationCompactAdaptation(horizontal:vertical:)`](/documentation/SwiftUI/View/presentationCompactAdaptation(horizontal:vertical:)) modifier to override this behavior. ### Breakthrough effect In visionOS, most system presentations appear with a breakthrough effect by default. To change how the enclosing presentation breaks through content occluding it, use [`presentationBreakthroughEffect(_:)`](/documentation/SwiftUI/View/presentationBreakthroughEffect(_:)), like in the following example: ```swift .popover(isPresented: $isShowingPopover) { Text("Popover Content") .padding() .presentationBreakthroughEffect(.prominent) } ``` --- Copyright © 2026 Apple Inc.
