Discussion

important:

You can call this method from synchronous code using a completion handler, as shown on this page, or you can call it as an asynchronous method that has the following declaration:

class func reloadContentBlocker(withIdentifier identifier: String) async throws

For information about concurrency and asynchronous code in Swift, see Calling Objective-C APIs Asynchronously.

Call this method when your extension’s content-blocking rules change.
