# UTF8Span.UnicodeScalarIterator

Iterate the Unicode.Scalars contents of a UTF8Span.

## Declaration

```swift
@frozen struct UnicodeScalarIterator
```

## Overview

Overview func printScalarValues(_ string: borrowing String) {     var iterator = string.utf8Span.makeUnicodeScalarIterator()     while let scalar = iterator.next() {         print(scalar.escaped(asASCII: true))     } }

let string = "A🎉" printScalarValues(string) // Prints "A" // Prints "\u{0001F389}"
