# alignmentGuide(_:computeValue:) Sets the view’s vertical alignment. ``` @preconcurrency nonisolated func alignmentGuide(_ g: VerticalAlignment, computeValue: @escaping @Sendable (ViewDimensions) -> CGFloat) -> some View ``` ## Parameters `g` A `VerticalAlignment` value at which to base the offset. `computeValue` A closure that returns the offset value to apply to this view. ## Return Value A view modified with respect to its vertical alignment according to the computation performed in the method’s closure. ## Discussion Use `alignmentGuide(_:computeValue:)` to calculate specific offsets to reposition views in relationship to one another. You can return a constant or can use the `ViewDimensions` argument to the closure to calculate a return value. In the example below, the weather emoji are offset 20 points from the vertical center of the `HStack`. ``` VStack { Text("Today's Weather") .font(.title) .border(.gray) HStack { Text("🌧") .alignmentGuide(VerticalAlignment.center) { _ in -20 } .border(.gray) Text("Rain & Thunderstorms") .border(.gray) Text("⛈") .alignmentGuide(VerticalAlignment.center) { _ in 20 } .border(.gray) } } ``` Changing the alignment of one view may have effects on surrounding views. Here the offset values inside a stack and its contained views is the difference of their absolute offsets.  --- Copyright © 2026 Apple Inc.
