There is a need to recognize numbers through the camera built into the iPhone. Like how a word lens recognizes letters, the same thing should be done with numbers. Most often, the numbers will be printed, but if it is possible to recognize handwritten ones, it will be just super. Are there any out of the box solutions for this? I honestly admit that I am far from iOS development and decided to start learning by writing, as it seems to me, a simple application.

I am currently dealing with exactly the same problem. In any case, cheap and cheerful - tessaract. For money - abby mobile ocr.
There are also cloud services, but it's too long to wait there :(. For tessaract to give good results, I recommend using opencv to process the photo before recognition. Or take the GPUImage library and process it with it. Convert to grayscale, process with a treshold filter. This will give good results.Link
github.com/ldiqual/tesseract-ios from the comment above - I personally confirm that it works.Only with dancing with a tambourine :) There will be questions, write in a personal .

From what I have found so far, there are two libraries Tesseract and ABBYY Mobile OCR.
