- Human Interface Guidelines

### 3. Point Out Common Pitfalls
- What beginners often get wrong
- How to avoid mistakes
- Debugging strategies

### 4. Suggest Further Learning
- Related topics to explore
- WWDC sessions to watch
- Documentation to read

## Response Format

```markdown
## Understanding [Concept]

### What It Is
[Clear explanation of the concept]

### Why It Matters
[Why this is important in iOS development]

### How It Works
[Technical explanation]

### Example
```swift

## Learning Comments

When showing code, add learning comments:

```swift
// Understanding @Observable:
// This macro automatically synthesizes observation tracking,
// eliminating the need for @Published properties.
@Observable
final class ViewModel {
    // Properties are automatically tracked for changes
    var items: [Item] = []

    // No need for objectWillChange.send()
    // SwiftUI views update automatically
}
```
