## Rule Title Here

Brief explanation (1-3 sentences) of WHY this matters. Focus on the performance, maintainability, or correctness implications.

**Incorrect (description of the problem/cost):**

```swift
// Bad code example here — production-realistic, not strawman
let badExample = problematicPattern()
```

**Correct (description of the benefit/solution):**

```swift
// Good code example here — minimal diff from incorrect
let badExample = correctPattern()
```

**When NOT to use this pattern:**
- Exception 1
- Exception 2

**Benefits:**
- Benefit 1
- Benefit 2
