# init(_:systemImage:isOn:)

Creates a toggle that generates its label from a localized string key and system image.

## Declaration

```swift
nonisolated init(_ titleKey: LocalizedStringKey, systemImage: String, isOn: Binding<Bool>)
```

## Parameters

- `titleKey`: The key for the toggle’s localized title, that describes the purpose of the toggle.
- `systemImage`: The name of the image resource to lookup.
- `isOn`: A binding to a property that indicates whether the toggle is on or off.

## Discussion

Discussion This initializer creates a Text view on your behalf, and treats the localized key similar to init(_:tableName:bundle:comment:). See Text for more information about localizing strings.
