Completely rewritten in Swift and SwiftUI for iOS18 and newer, uses Vision API's for the image processing.

The Application has been ported to SWIFT and while at it some things have been fixed ;-) 1. The taken Image now can be scanned using OCR and the recognized Numbers will be added to the Board. 2. If you don't have any Examples at Hand, the App can create a new Board in three different difficulty Levels. We do hope you enjoy this update and look forward to all of your Feedback!

- Adopted to the iPhone 6 and iPhone 6 plus - Adopted to iOS8 - new Font for the Board

- iOS7 Compatibility

Modifications to fir the new screen size on the iPhone 5

- modified code to comply with iOS5
