This is your iOS storage decision tree in skill form. Instead of wandering through Stack Overflow threads about whether to use SwiftData, Core Data, files, or CloudKit, you get a structured framework covering everything from database choices to sync strategies to where files actually belong (Documents vs Caches vs Application Support). It targets iOS 17+ with newer iOS 26 features, pulls from recent WWDC sessions, and handles the common "why did my files disappear" debugging scenarios. Worth having on hand if you're tired of second-guessing storage architecture decisions or fixing sync issues after the fact.
