WebPage.DialogPresenting

protocol · iOS 26.0+ · SDK 27.1

protocol DialogPresenting

Allows providing custom behavior to handle JavaScript actions and provide a response. Typically when handling these, some UI should be presented to the user for them to provide a response, which will then be communicated back to JavaScript. When these methods are invoked, JavaScript is blocked until the async method returns.
