# HomeAccessorySettingsContainer

A snapshot of an accessory’s settings and their current values.

```
@MainActor protocol HomeAccessorySettingsContainer
```

## Overview

Create a type that adopts this protocol, with a property for each setting. Declare each property with one of the setting property wrappers: [`HomeAccessoryToggleSetting`](/documentation/HomeExtensions/HomeAccessoryToggleSetting), [`HomeAccessoryRangeSetting`](/documentation/HomeExtensions/HomeAccessoryRangeSetting), [`HomeAccessoryEnumSetting`](/documentation/HomeExtensions/HomeAccessoryEnumSetting), [`HomeAccessoryTextFieldSetting`](/documentation/HomeExtensions/HomeAccessoryTextFieldSetting), or [`HomeAccessoryInformationSetting`](/documentation/HomeExtensions/HomeAccessoryInformationSetting). Each wrapper stores details such as the setting’s identifier and label.

List the settings’ projected values (with the `$` prefix) in [`availableSettings`](/documentation/HomeExtensions/HomeAccessorySettingsContainer/availableSettings), in the order you want them to appear. For example:

```swift
struct ThermostatSettings: HomeAccessorySettingsContainer {
    static let ecoModeID = "eco-mode"

    @HomeAccessoryToggleSetting(id: Self.ecoModeID, label: "Eco Mode")
    var ecoMode: Bool?

    var availableSettings: [any HomeAccessorySetting] { [$ecoMode] }

    init(ecoMode: Bool? = nil) { self.ecoMode = ecoMode }
}
```

Store identifiers as static constants so your provider can reuse them. Your provider should create a new container each time [`settings(context:for:)`](/documentation/HomeExtensions/HomeAccessorySettingsProvider/settings(context:for:)) runs, rather than retaining one.
