```

## Return Value

Return Value The progress of the method.

## Discussion

Discussion important: This method is available in iOS 12.5, and in iOS 13.5 and later. This method allows recalculating a new score using different configuration parameters. If you’ve previously called   detectExposures(configuration:diagnosisKeyURLs:completionHandler:), any keys you submitted in the previous 14 days are cached. Only use this method if your app specifies an ENAPIVersion of 2 in its Info.plist file, because older versions did not cache keys. important: On iOS 13.6 and later, you’re limited to using this method a maximum of 15 times per 24-hour period. If you’re on iOS 13.7 and later and specify 2 as the ENAPIVersion in your app’s Info.plist file, you’re limited to using this method a maximum of 6 times per 24-hour period. On iOS 13.5, you can only submit 15 uncached key files per 24-hour period, regardless of the number of API calls you make.
