# init(_:)

Creates a string corresponding to the given collection of Unicode scalars.

## Declaration

```swift
init(_ unicodeScalars: String.UnicodeScalarView)
```

## Parameters

- `unicodeScalars`: A collection of Unicode scalar values.

## Discussion

Discussion You can use this initializer to create a new string from a slice of another string’s unicodeScalars view. let picnicGuest = "Deserving porcupine" if let i = picnicGuest.unicodeScalars.firstIndex(of: " ") {     let adjective = String(picnicGuest.unicodeScalars[..<i])     print(adjective) } // Prints "Deserving" The adjective constant is created by calling this initializer with a slice of the picnicGuest.unicodeScalars view.
