# boolValue

The Boolean value of the string.

## Declaration

```swift
var boolValue: Bool { get }
```

## Discussion

Discussion This property is true on encountering one of “Y”, “y”, “T”, “t”, or a digit 1-9—the method ignores any trailing characters. This property is false if the receiver doesn’t begin with a valid decimal text representation of a number. The property assumes a decimal representation and skips whitespace at the beginning of the string. It also skips initial whitespace characters, or optional -/+ sign followed by zeroes.
