# detailSubtitle

The detail card’s subtitle.

## Declaration

```swift
var detailSubtitle: String? { get set }
```

## Discussion

Discussion The template only displays a detail card when the user selects a point of interest. If this property is nil, the card displays the point of interest’s subtitle instead.
