I am currently developing my submission for the Swift Student Challenge 2026. My project focuses on financial literacy for children ("Canteen Hero"), and I want to ensure it runs flawlessly during the judging process. I have two specific questions regarding the environment: Which iOS/iPadOS version do judges typically use for testing? Should I assume they will be using the latest stable release (e.g., iOS 19/iPadOS 19) or a specific beta version? Device Compatibility: Is it a requirement to design the app for all previous iOS versions (backward compatibility), or is it acceptable to target only the latest APIs (iOS 18/19+) to utilize modern features like SwiftData and the latest SwiftUI animations? Thank you for your guidance!
