iMac 24 inch for App Development

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?

Hardware Advice

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

Bypassing AppStore

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.

App Store Connect Question

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?

How to Scan and Process a Suduko Puzzle

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?
