Instruction 01

Whether your app is an accessibility tool, data-entry automation or a document scanner, the ability to recognize and work with text opens new possibilities. Apple’s Vision Framework provides a few request types that are specifically designed for these tasks. Here’s a chart for the main text-related Vision request types along with their response observation types and when they were introduced.

iOS 11

• VNDetectTextRectanglesRequest and VNTextObservation: Detects regions of text in an image.

iOS 13

• VNDetectTextRectanglesRequest and VNTextObservation: Performs Optical Character Recognition (OCR) to detect and recognize text.

iOS 15

• VNRecognizeHandwritingRequest and VNRecognizedTextObservation: Recognizes handwritten text in images.

Differentiating Between VNDetectTextRectanglesRequest and VNRecognizeTextRequest

When the Vision Framework first arrived, VNDetectTextRectanglesRequest was the only option. This request type gave you the bounding boxes of all the areas in an image that likely contain text. If you wanted to actually perform recognition, you had to use a CoreML model.
