I'm using VNRecognizeTextRequest with: request.recognitionLevel = .accurate request.usesLanguageCorrection = false request.recognitionLanguages = ["en-US", "de-DE"] Basically code is taken from https://developer.apple.com/documentation/vision/reading_phone_numbers_in_real_time But when performs it by VNImageRequestHandler. I'm getting the following warning: Could not determine an appropriate width index for aspect ratio 0.0062 Could not determine an appropriate width index for aspect ratio 0.0078 Could not determine an appropriate width index for aspect ratio 0.0089 ... I tried to use fast for recognitionLevel and it helped but results are not that good as in accurate level. Can you suggest how to fix the problem accurate?
