# AttributeScope

A type that organizes attributes into a grouping, and supports dynamic member lookup and serialization of attribute keys.

```
protocol AttributeScope : DecodingConfigurationProviding, EncodingConfigurationProviding, SendableMetatype
```

## Overview

Attribute owners — typically frameworks — define attributes with [`AttributedStringKey`](/documentation/Foundation/AttributedStringKey) types. To allow access to attributes with dynamic member lookup, owners create one or more structures that conform to [`AttributeScope`](/documentation/Foundation/AttributeScope). The scopes provide short names for their attributes that map to the [`AttributedStringKey`](/documentation/Foundation/AttributedStringKey) type. The following example shows how to do this:

```swift
struct TextStyleAttributes : AttributeScope {
    let foregroundColor : ForegroundColorAttribute // ForegroundColorAttribute.Value == Color
    let backgroundColor : BackgroundColorAttribute // BackgroundColorAttribute.Value == Color
    let underlineStyle : UnderlineStyleAttribute // UnderlineStyleAttribute.Value == UnderlineStyle
    // etc.
}
```

This allows callers to use a syntax like `myAttributedString.foregroundColor = .red`.

## Topics

### Supporting Coding Configurations

[`encodingConfiguration`](/documentation/Foundation/AttributeScope/encodingConfiguration)

The configuration for encoding the attribute scope.

[`decodingConfiguration`](/documentation/Foundation/AttributeScope/decodingConfiguration)

The configuration for decoding the attribute scope.
