Discussion
Implement this optional method to ensure that the accessibility element representing the picker view provides an appropriate hint for each component. 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(_:accessibilityHintForComponent:) method.
