I am trying to use an NSSearchToolbarItem using AppKit directly in Objective-C. If I perform a search and then click the cancel icon, my target/action is called while the NSSearchField still contains the search text (not yet cleared) and the delegate has not yet received the ending search invocation. In other words, it looks exactly the same as if the user had submitted the same search twice. Google's AI suggested using the controlTextDidChange method, but that was deprecated long ago. My current solution is to ignore searches that appear redundant (although they may not be, if the data being searched changes). This is on macOS 26.6.
