# updateSections(_:)

Adds, removes, reorders, or updates the list’s sections.

## Declaration

```swift
func updateSections(_ sections: [CPListSection])
```

## Parameters

- `sections`: An array of sections to display.

## Discussion

Discussion This method is multipurpose. Use it to add new sections to the list, to remove or reorder existing sections, and to update a section’s appearance. At runtime, use maximumSectionCount to determine the maximum number of sections the list can display. CarPlay trims the array if its size exceeds this limit.
