Tells you that the current writing tools session ended.

Use this method to undo any actions you took at the start of a writing tools session to modify your app’s behavior. The text view calls this method after the writing session finishes. At this point, the text view contains the final text the person chose.

DesktopNSTextViewControlMBS.textViewWritingToolsWillBegin   New in 24.5

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
event	Cocoa Controls	MBS MacCocoa Plugin	24.5	✅ Yes	❌ No	❌ No	❌ No

Tells you that an interaction with the writing tools interface is about to begin.

Use this method to take any necessary steps to prepare your app for writing tools interactions. During the course of a writing tools session, the writing tools UI suggests changes to the text view’s text. It also allows the person to toggle between the original and replacement text before choosing one. To avoid issues while these changes occur, save any current data to disk and and disable features that might modify your view’s text storage while the session is active. For example, disable iCloud synchronization until the session ends. Reenable those features when the session ends.

The text view calls this method when the person requests the writing tools interface, but before the interface makes any changes to your content. Because the session isn’t active yet, the writingToolsActive property of the text view is NO while this method executes. The value of that property resolves to YES only after the method returns.
