Deprecation warning
Please note that this is outdated documentation for an older release of the Scandit Barcode Scanner SDK.
We are deprecating the 5.x API on all platforms (except Linux). Release 5.19 in April 2021 will be our final. Applications running 5.x will continue to work, and we will continue to release critical bug fixes and security patches only, for one year. We encourage you to migrate to 6.x and take advantage of our latest / advanced features and improved performance.
You'll find the updated documentation at: Data Capture SDK Documentation for iOS

Detailed Description
Protocol for accessing the processed sample buffers.

Method invoked whenever a frame has been processed by the barcode scanner.
This method is called on the SBSBarcodePicker::processFrameDelegate whenever the barcode scanner has finished processing a frame.
- Parameters
-
barcodePicker the barcode picker instance that processed the frame frame the sample buffer containing the actual frame data. session The current scan session containing the state of the recognition process, e.g. list of codes recognized in the last processed frame. The scan session can only be accessed from within this method. It is however possible to use codes returned by SBSScanSession::newlyRecognizedCodes outside this method.
This method is invoked from a picker-internal dispatch queue. To perform UI work, you must dispatch to the main queue first. When new codes have been recognized, this method is invoked after SBSScanDelegate::barcodePicker:didScan is called on the SBSBarcodePicker::scanDelegate.
