protocol ObjectiveCConvertibleAttributedStringKey : AttributedStringKey

A protocol that defines Objective-C interoperability with an attribute key's value type. Conform to this protocol to allow your attributed string key to customize its Objective-C conversion behavior. This allows you to define an Objective-C value type and provide methods to convert to and from this type. Attributed string keys that don't conform to this protocol cast the value to <doc://com.apple.documentation/documentation/swift/anyobject> before converting to Objective-C. When converting from Objective-C, the value casts to the key's ``AttributedStringKey/Value`` type. In cases where Swift types bridge automatically to Objective-C types, like <doc://com.apple.documentation/documentation/swift/string> to ``NSString``, this default behavior is adequate. But for unbridged value types, you need to conform to this protocol and provide the conversion methods.
