💡 What:
Replaced .onTapGesture on the "Add Step" UI element and the MacroStepRow view wrapper inside MacroEditorSheet.swift with standard Button structures using .buttonStyle(.plain).

🎯 Why:
Using .onTapGesture on general View components (like HStack or layout blocks) is an accessibility anti-pattern in SwiftUI. It makes elements interactive for pointer devices but prevents them from receiving proper keyboard focus or being identified as actionable buttons by screen readers like VoiceOver. This fix ensures that macros can be edited accessible across input paradigms.

📸 Before/After: No visual changes. Preserved .contentShape(Rectangle()) to maintain exact clickable area and .onHover states.

Accessibility:

  • Enabled Tab key focus navigation for Macro list items.
  • Ensured items are correctly identified by VoiceOver as interactive Buttons rather than static groups.

Summary by CodeRabbit

  • Accessibility

    • Improved keyboard and VoiceOver support when selecting macro steps.
    • Macro step rows and the “Add Step” row now behave as accessible buttons while retaining their existing appearance and interactions.
  • Documentation

    • Added guidance recommending accessible button-based interactions for structural views.

…Keyboard/VoiceOver A11y

This patch replaces `.onTapGesture` modifiers with `.buttonStyle(.plain)` `Button` wrappers on interactive list rows in MacroEditorSheet. This ensures these UI components are accessible to keyboard navigation (Tab focus) and correctly identified by screen readers like VoiceOver.

The macro editor replaces .onTapGesture handlers with plain-styled Button wrappers for step selection and adding steps. A dated palette note documents the accessibility guidance.

Button-based macro row actions

Macro step rows and the add-step row now use plain-styled buttons. The palette note documents the related accessibility guidance.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to b6175

The macro editor may trigger the wrong action or prevent independent keyboard and VoiceOver access because each row button contains separate Duplicate and Delete buttons. The row action and child actions should be separated before merging.

Apple SwiftUI nested Button inside Button macOS accessibility keyboard VoiceOver behavior

💡 Result:

Nesting buttons directly inside other buttons in SwiftUI is considered an anti-pattern and generally leads to undefined or unintended behavior regarding both standard user interactions and accessibility [1][2][3]. Interaction and Technical Behavior From a technical standpoint, SwiftUI does not officially support nested buttons [2]. While the code may compile, placing a Button inside the label of another Button often results in hit-testing conflicts where the inner button's action may fail to trigger, or the outer button's tap animation is triggered inadvertently [1][2][3]. To achieve a layout where multiple interactive elements exist in close proximity, developers should instead use sibling buttons within a container like an HStack or ZStack, or use non-button views (like images or text) with tap gestures that have appropriate accessibility traits applied [1][4][2][3]. VoiceOver Accessibility Behavior When buttons are nested, VoiceOver’s representation of the interface becomes ambiguous [5]. Accessibility technologies rely on a predictable, tree-like structure of elements [6][7]. Nesting buttons breaks this hierarchy, which can lead to: 1. Inconsistent Focus: VoiceOver may fail to expose the inner button as a distinct, focusable element [8]. 2. Semantic Conflicts: Screen readers may ignore the labels of child elements when combined within a single parent element, unless explicitly configured [8]. 3. Navigation Issues: The accessibility tree becomes difficult to navigate efficiently because the relationship between the parent and child controls is not semantically clear [6][7]. Recommended Approach To create accessible, functional UIs on macOS: - Avoid nesting: Use sibling buttons inside stacks (HStack, VStack, or ZStack) [1][3]. - Use Custom Actions: If you must have a complex view with multiple interactive areas, keep the view as a single element and add functionality using the.accessibilityAction(named:_:) modifier [6][9]. This allows you to expose multiple actions to VoiceOver without creating a complex or invalid nested button hierarchy [6][9]. - Proper Traits: If you create a custom interactive view that is not a native Button, ensure you add the.isButton accessibility trait so VoiceOver correctly identifies the element as an actionable control [5][4].

Keep the row action separate from the child actions.

MacroStepRow contains Duplicate and Delete buttons, but the outer Button wraps the entire row and opens the editor. SwiftUI does not support nested buttons reliably; child activation can trigger the outer action or prevent independent keyboard and VoiceOver navigation. Make the row button and child buttons sibling controls.
