Discussion
Use this method to provide descriptive information for the components of a picker view. Your attributed string may include the UIAccessibilitySpeechAttributeLanguage attribute, which lets you use different language synthesizers for different parts of the string. The system prefers this method over the pickerView(_:accessibilityLabelForComponent:) method.
