Quick Start

Core Design Framework:

1. Spatial Code Mapping - Represent code relationships visually, not just hierarchically
2. Contextual AI Layers - AI assistance appears inline, never in separate panels
3. Progressive Disclosure - Start simple, reveal complexity on demand
4. Gesture-First Interactions - Design for touch/trackpad, keyboard shortcuts follow

Immediate Template:

Canvas Layout:
├── Active Code View (60% screen)
├── Contextual AI Strip (15% right edge)  
├── Spatial Navigator (20% left)
└── Command Palette (5% bottom)

Workflow

Progress:

• Map Developer Mental Model: Interview 5+ developers, document their spatial thinking about code
• Define Core Gestures: Pinch-to-zoom code scope, swipe between files, long-press for AI context
• Design AI Integration Points: Code completion, error explanation, refactor suggestions
• Create Interactive Prototypes: Use Figma/Framer for gesture testing
• Test Cognitive Load: Measure task completion time vs traditional IDEs
• Refine Visual Hierarchy: Apply SF Symbols, consistent spacing, Apple typography scales

Key Design Patterns:

• Inline Expansion: Click function name → code expands in place
• Contextual Overlays: Hover variable → type info appears as card
• Predictive Navigation: Start typing → AI highlights likely destinations

Examples

Example 1: File Navigation Redesign Input: Traditional folder tree with nested directories Output: Circular dependency graph where file size = importance, connections show actual imports/references, recent files glow with warm colors

Example 2: Error Display Transformation Input: Red squiggly lines with popup text "Undefined variable 'userName'" Output: Inline gentle highlight with AI suggestion bubble: "Did you mean 'username'? I see it defined 3 lines above" + one-tap fix button

Example 3: Code Completion Enhancement Input: Dropdown list of 20 method names Output: 3-suggestion overlay with explanations: "authenticate()" with preview "Validates user session", confidence indicator, and natural language prompt "or describe what you want to do"

Best Practices

• Use SF Pro Display for code, SF Pro Text for UI elements
• Apply 8pt grid system consistent with Apple's spacing
• Leverage depth through shadows instead of borders for panels
• Implement haptic feedback for gesture confirmations on trackpad
• Design dark mode first, light mode as variant
• Maintain 44pt minimum touch targets for all interactive elements
• Use semantic colors (systemBlue for links, systemRed for errors)
• Respect reduce motion settings with alternative animations

Common Pitfalls

• Overusing gradients: Stick to solid colors with occasional subtle gradients
• Ignoring accessibility: Always test with VoiceOver, high contrast modes
• Too many AI suggestions: Limit to 3 options maximum to prevent choice paralysis
• Breaking muscle memory: Keep Cmd+S, Cmd+Z, and other universal shortcuts
• Inconsistent information density: Maintain consistent padding and text sizes across views
• Forgetting about external monitors: Design scales properly across different screen sizes
• AI that talks too much: Prefer concise explanations over verbose descriptions
