Modern Core Data
summary
Core Data can be modernized by small Swift wrappers that make it more readable and less error‑prone: uses protocol and protocol extensions to map entities to classes and to provide a one-line fetch request with default sort descriptors, replaces fragile string keys with a type-safe KVC pattern (nested enums + compiler-checked keys), supplies a generic ValueTransformer built from two closures, and adds trivial performChanges and managed-object observer helpers — these wrappers work and preserve Core Data’s original behavior.
