```swift
func startClipBuffering(completionHandler: (@Sendable ((any Error)?) -> Void)? = nil)

- `completionHandler`: The system invokes this closure when recording starts. The system passes an error object to the closure if it encountered a problem.

## 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: func startClipBuffering() async throws For information about concurrency and asynchronous code in Swift, see Calling Objective-C APIs Asynchronously.
