analyze(completionHandler:)

Declaration

func analyze(completionHandler: @escaping  @Sendable (Bool) -> Void)

func analyze() async -> Bool

Parameters

• completionHandler:

  A completion closure (Swift) or block (Objective-C) the analyzer calls when it finishes analyzing a file.

Mentioned in

• Classifying Sounds in an Audio File

Discussion

The method executes asynchronously and calls the completion handler after the analyzer finishes analyzing the entire file. The audio file analyzer sends errors to each request’s results observer.

If you call the cancelAnalysis() method, the analyzer calls your completion handler and passes false because it can’t reach the end of the file.
