appending(_:)

Returns a new text suggestions delegate of the same suggestion item type with the items and behaviors of the receiving delegate and other concatenated. When the returned delegate is connected to a text field, all suggestion items provided from the first suggestions delegate appear before all those from the second suggestions delegate, visually separated by a separator.
