Swift provides the `Bool` type, which can have two values: `true` and `false`.

```swift
var done = false
done = true
```

Booleans are especially useful with conditional control structures like `if` statements or the ternary conditional operator:

```swift
var done = true

if done == true {
    //code
}
```
