Discussion
Use this method to provide the text system with the same transform you apply to the text in your view. Providing this transform lets the system render the caret accurately relative to the text. For example, if the text is rotated, return a transform with the same rotation factor to ensure the caret appears in the correct position and orientation relative to the text. If you don’t implement this method, the system applies the identity transform to the caret.
