This is a routing skill that directs Claude to the right iOS data persistence solution based on your needs. Whether you're working with SwiftData, Core Data, GRDB, CloudKit sync, or handling serialization and encryption with CryptoKit, it acts as a decision layer to keep data work organized. The mandatory language ("you MUST use this skill") suggests it's part of a larger axiom framework where routing matters for consistency. With 205 installs and 945 GitHub stars, it's seeing real adoption. If you're building iOS apps with multiple data persistence needs and want to avoid decision fatigue, this handles the triage.
