I would like to know how to scan an image containing a Suduko puzzle and to be able to identify all the numbers in the puzzle and the cell in which those numbers are written. I have experimented with SwiftUI's Vision and CoreML without success. Is anyone able to give me pointers on how to do this?

Can anyone advise on how to code an extension to String to implement the following protocol: protocol GenericPasswordConvertible: CustomStringConvertible { init<D>(rawRepresentation data: D) throws where D: ContiguousBytes var rawRepresentation: Data { get } } Thank you!

I have a late 2013 iMac and so Catalina is the latest MacOS I can install. Therefore, Xcode 12.4 is the latest version of Xcode I can have on my iMac. I would like to use my iPhone 12 as a simulator to see how my app looks but this is not possible as I have iOS 16 installed on my phone. I understand that TestFlight can be used to beta test apps before they are made available in the App Store. My app is nowhere near finished and in fact all I want to is upload a test project to see how some features of my app would appear on a real device. When submitting an app to App Store Connect so that in can be downloaded via TestFlight, do I need to provide full documentation as is required when submitting an app to the App Store for review?

Hello. I'm writing a generic Picker view and would like to pass the required PickerStyle to the view. Can anyone tell me how to pass PickerStyle as an argument? Thank you

Hello I want to write an app for my son's business. Is there a way to bypass the AppStore to install the app on his iPhone? I know I can use his phone as a simulator but that requires his phone to be in Developer mode which means his phone will be less secure.

Hello. I'm planning to replace my late-2013 iMac with a mac mini and wonder whether anyone has any advice on the minimum configuration I will need. My primary focus is app development (i.e. Xcode/SwiftUI). i.e. recommended memory, M2 or M2 Pro Also a recommended 27inch display (not Studio Display...too expensive!) Thank you

Hello. Can anyone offer any feedback on using an iMac 24 inch for app development? Is a 24 inch display frustratingly small (as compared to a 27 inch) or is it acceptable?
