# init(booleanLiteral:)

Creates an instance initialized to the given Boolean value.

```
init(booleanLiteral value: Self.BooleanLiteralType)
```

## Parameters

`value`

The value of the new instance.

## Discussion

Do not call this initializer directly. Instead, initialize a variable or
constant using one of the Boolean literals `true` and `false`. For
example:

```
let twasBrillig = true
```

In this example, the assignment to the `twasBrillig` constant calls this
Boolean literal initializer behind the scenes.
