Hello thanks for the reply okay so im using the tesseractOCR iOS library on this repo https://github.com/gali8/Tesseract-OCR-iOS. I can use this library in my iOS app without issues as long as I target a device, or if i target a Rosetta based simulator. But what I can't seem to get working is to target an M1 simulator. The reason being I would like to eventually embed this sdk into a react-native application. And when using react native npx command it doesn't let you target rosetta based simulators. Is this library just way too out of date? and I should just use the other libraries you posted?
Also the Xcode project for this Tesseract-OCR-iOS library has 5 sub modules, libtiff, libpng, libjpeg, libtesseract, and liblept. Each of those libraries I was able to use cmake to create an xcode project, then pointed to an m1-simulator and got a new module which i replaced in the Tesseract-OCR-iOS project. But then that's when i get this error and I'm not sure how to proceed past this point.
