This is a built-in template used for filling the body of an implemented -copyWithZone: method when it is generated for class without any ivars, e.g. when calling the Code | Generate | -copyWithZone:... function. The template is editable. Along with Objective-C expressions and comments, you can also use predefined variables that will be then expanded into the corresponding values.

Predefined variables will take the following values:
${RETURN_TYPE}		return type of a created method
${DEFAULT_RETURN_VALUE}		value returned by the method by default
${CONTAINING_CLASS}		name of the class where the method is implemented
All the predefined variables from the C File Header template (Includes tab) are also available (e.g. ${USER}, ${DATE}, etc.)
