# localizedUppercase

Returns a version of the string with all letters converted to uppercase, taking into account the current locale.

## Declaration

```swift
var localizedUppercase: String { get }
```

## Discussion

Discussion Case transformations aren’t guaranteed to be symmetrical or to produce strings of the same lengths as the originals. See lowercased for an example.
