# nextBool()

Generates and returns a new random Boolean value.

## Declaration

```swift
func nextBool() -> Bool
```

## Return Value

Return Value A random Boolean value.

## Discussion

Discussion Typically, custom classes implementing this protocol should implement the nextBool() method based on the value returned by the nextInt(upperBound:) method. Alternative implementations are possible, but may lead to less uniform results.
