# bool(forKey:)

Returns the Boolean value associated with the specified key.

## Declaration

```swift
func bool(forKey aKey: String) -> Bool
```

## Parameters

- `aKey`: The key to retrieve from the iCloud key-value store.

## Return Value

Return Value The Boolean value associated with aKey, or false if the key isn’t present.

## Discussion

Discussion This method automatically coerces certain values to their equivalent Boolean meanings. For example, it coerces the numbers 1 and 1.0, and the strings “true”, “YES”, and “1” to the value true.
