# localizedCaseInsensitiveContains(_:)

Returns a Boolean value indicating whether the given string is non-empty and contained within this string by case-insensitive, non-literal search, taking into account the current locale.

## Declaration

```swift
func localizedCaseInsensitiveContains<T>(_ other: T) -> Bool where T : StringProtocol
```

## Discussion
