WWDC 2024 mentioned that the OCR feature from the Vision framework has support for "Korean, Swedish, and Chinese", but the Swedish support does not seem to be available...
Running either
print(try? VNRecognizeTextRequest().supportedRecognitionLanguages())
or
var ocrRequest = RecognizeTextRequest(.revision3)
print(ocrRequest.supportedRecognitionLanguages)
did not print out Swedish as one of the supported languages, but Korean and Chinese are.
Tested on early versions of iOS 18 developer beta, and the latest version of iOS 18.1 (22B5054e).
