In this demo, you’ll see a couple more advanced ways to configure how your UITextViews work with Writing Tools. Open the starter project for Lesson Two and select CustomTextView.swift, which is the UIKit version of the cover letter drafting view.

Defining Ignored Text Ranges

Using the cover letter view as an example, here’s how you can implement a range of text Writing Tools will not attempt to modify. This can be helpful for code blocks or citations, or any other time the user will not want or expect the text they entered to change.

Preventing Unexpected Data Loss or Changes

Next, you’ll see how to use textViewWritingToolsWillBegin() and textViewWritingToolsDidEnd() to manage app operations when Writing Tools are active.
