Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to The accessibility change replaces row tap handling with a Button, but the current row still nests Edit and Delete controls inside that Button and may allow keyboard or assistive-technology activation to edit inherited layers that should be read-only. This can cause ambiguous navigation and unintended layer-specific command-wheel overrides, so the interaction structure and editability guards should be corrected before merge. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

Apple SwiftUI allowsHitTesting false Button label disabled keyboard activation Button disabled documentation
💡 Result:
In SwiftUI, the allowsHitTesting(:) modifier controls whether a view participates in hit-testing for pointer or touch interactions, making it transparent to such inputs [1][2][3]. However, its effect on keyboard activation and accessibility is distinct from its effect on pointer events [1][4]. Effect on Button Interaction: When you set allowsHitTesting(false) on a Button, the button stops responding to direct pointer or touch interactions (taps or clicks) [2][3]. The taps will pass through to the underlying views [5][2][3]. Crucially, allowsHitTesting(:) is primarily designed for hit-testing logic and does not disable the view at the accessibility or keyboard event layer in the same way the disabled(:) modifier does [1][2]. Accessibility and Keyboard Activation: If you want to ensure a Button is also ignored by assistive technologies (like VoiceOver) or keyboard-based interaction (like Full Keyboard Access), allowsHitTesting(false) is often insufficient [1][4]. To explicitly manage whether an element responds to accessibility interaction, you should use the accessibilityRespondsToUserInteraction(:isEnabled:) modifier [4][6]. Comparison with disabled(:): - disabled(:): This is the standard way to disable a Button. It stops both interaction and accessibility activation, and it automatically updates the view's appearance to indicate it is disabled [2][7]. - allowsHitTesting(false): This hides the view from pointer/touch hit-testing without changing its visual appearance [2][8]. It does not necessarily prevent the button from being focused or activated via accessibility or keyboard technologies [1][4]. If your goal is to make a button non-interactive and inaccessible while keeping its appearance unchanged, you may need to combine allowsHitTesting(false) with accessibilityHidden(true) or accessibilityRespondsToUserInteraction(false) to fully exclude it from both pointer and assistive technology interaction [4][6].

Disable the outer row button when canEdit is false.
An inherited layer sets canEdit to false, but the enabled outer Button can still activate through keyboard or accessibility and set editingAction, presenting CommandWheelActionSheet. Apply .disabled(!canEdit) to the outer Button and remove the label-only .allowsHitTesting(canEdit) modifier.

SwiftUI nested Button controls accessibility keyboard focus allowsHitTesting label outer Button macOS
💡 Result:
Nesting Button controls in SwiftUI is strongly discouraged and not officially supported, as it creates ambiguous behavior for both hit testing and accessibility navigation [1][2]. When a button is placed inside the label of another button, the system may struggle to distinguish which action to perform, leading to unpredictable results where the outer button often takes precedence or both trigger simultaneously [1][2][3]. For macOS development, use these strategies instead: 1. Hit Testing and Interaction: If you require multiple distinct actions within a single UI element (e.g., a list item with a primary action and a secondary sub-action), do not nest buttons. Instead, use a layout container like HStack or ZStack [1]. For the sub-action, apply a button style that minimizes visual interference, such as.buttonStyle(.borderless) [4]. To prevent a child element from blocking hits intended for a parent, use.allowsHitTesting(false) on specific sub-views, though this should be used carefully to avoid breaking intended interactions [5][6]. 2. Accessibility and Keyboard Focus: Assistive technologies and keyboard navigation rely on a clear tree structure of interactive elements [7]. Nesting buttons violates this structure, making it difficult for VoiceOver and Full Keyboard Access to determine which element to focus [7][8]. Instead of nesting, manage accessibility and focus programmatically: - To treat a group of items as a single focusable unit, use.accessibilityElement(children:.combine) [7][9]. - To expose multiple actions on a single element without physical nesting, use the.accessibilityAction(named:_:) modifier [9]. - For fine-grained keyboard navigation, use @FocusState (for standard keyboard input) or AccessibilityFocusState (for assistive technologies) to track and move focus between distinct, non-nested controls [10][11][12]. If you find yourself needing to nest buttons, it is a strong signal to rethink your UI component structure, such as moving the sub-action into a context menu, a separate button in an HStack, or using a dedicated custom control that handles these states explicitly [1][9][2].

site:developer.apple.com/documentation/swiftui allowsHitTesting false Button label parent Button SwiftUI
💡 Result:
In SwiftUI, you can prevent a specific view within a Button label from intercepting touch events by applying the allowsHitTesting(_:) modifier with a value of false [1]. When you apply.allowsHitTesting(false) to a view inside a button's label, that specific view will no longer participate in hit testing [1]. As a result, touch events occurring on that view will pass through to the parent Button, which will then handle the interaction as expected [1]. Example usage: Button(action: { print("Button pressed") }) { ZStack { Text("Click Me") // This view will ignore touch events, allowing the parent Button to handle them Circle.fill(Color.blue).allowsHitTesting(false) } } This technique is useful when you have decorative elements or overlays within a button's label that you do not want to interfere with the parent button's gesture recognition [1].

Separate row selection from Edit and Delete controls.
CommandWheelActionRow contains Edit and Delete Button controls, but the ForEach wraps the entire row in another Button. This creates an unsupported nested control hierarchy and can cause ambiguous keyboard focus and VoiceOver navigation.
When canEdit is false, .allowsHitTesting(false) causes events to pass to the outer Button. Its action still sets editingAction, so an inherited layer can open the edit sheet. Make selection a control containing only non-interactive content, keep Edit and Delete as sibling controls, and prevent edit actions when canEdit is false.

💡 What: Replaced
.onTapGesturewith aButtonwrapper onCommandWheelActionRowfor better accessibility support.🎯 Why:
.onTapGesturelacks out-of-the-box support for keyboard navigation and screen readers on macOS, failing to properly expose interactive UI elements.📸 Before/After: Visual appearance is unmodified thanks to
.buttonStyle(.plain).♿ Accessibility: Wrapping interactive list elements in a standard SwiftUI
