Objective C convert classifier model to a detector model from swift to Obj C

Hello, I have a Objective C objective classifier model - i want to make it to a detector model similar to below - however this project is in swift - so this needs to be converted to Obj C - you don't have to convert the whole project - only a part - as the current Obj C project attached does all of the video processing part. [login to view URL] Part that you have to convert is Parse Recognized Object Observations section- replace VNClassificationObjectObservation with VNRecognizedObjectObservation FINAL OUTPUT: Project similar to Apple documentation but in Obj C
