## Discussion

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: var rawData: Data { get async throws } For information about concurrency and asynchronous code in Swift, see Calling Objective-C APIs Asynchronously.
