Apple updated its Human Interface Guidelines for Sheets on March 24, 2026 to add guidance for button placement in the toolbar. "In iOS & iPadOS, the Cancel button belongs on the leading edge of the top toolbar." Time to update my apps 🙂 Documentation: developer.apple.com/design/human...

Seems like there’s a difference between “close” and “cancel” where “cancel” is a destructive action with an opposite confirm button. Close is non-destructive so it stays in the primary trailing spot

Yes, close is to my knowledge trailing in as it is usually the only toolbar button. However, the button in messages is actually labeled as a cancel button when using VoiceOver (makes sense, content gets lost when closing it).

🤯 I’m more lost than before 😂 We could also put the close at the leading edge, like in macOS (red).

There are new roles (close and confirm) along with a new initializer requiring no label at all.That's why there are so many checkmarks and xmarks in 26 Confirm -> save, cancel -> something gets lost, destructive -> delete, close exploreswiftui.com/library/butt... developer.apple.com/documentatio...

In SwiftUI (UIKit too?), there is the semantic cancellationAction ToolbarItemPlacement. “In iOS, iPadOS, tvOS, and watchOS, the system places cancellationAction items on the leading edge of the navigation bar.” Maybe there should be a closeAction too? developer.apple.com/documentatio...

There is a button role .close which places the button on the right side in the top toolbar: developer.apple.com/documentatio...
