Why I Chose Core Data Over SwiftData for Hive Notes

SwiftData is Apple's modern take on local persistence. It has a cleaner syntax, tighter SwiftUI integration, and less boilerplate. Core Data is the two-decade-old workhorse. For Hive Notes and its 15-entity data model, I needed reliability over novelty. Sometimes boring technology is exactly what you need.

The Technical Debt AI Migration Tools Leave Behind

Beyond Syntax: What AI Misses in Swift Migrations

Six months after your AI-assisted migration, the app is stable. The crashes are fixed. Production is humming along. But your development velocity has slowed to a crawl. Every new feature takes longer to implement than it should. Your team complains that the code "feels wrong."

Why AI-Migrated Code Compiles But Breaks in Production

Beyond Syntax: What AI Misses in Swift Migrations

The app launches perfectly. The test suite shows all green. Your code review finds nothing alarming. Three days after shipping to production, users start reporting that their carefully typed messages are getting truncated at seemingly random points. This is the invisible danger of AI-assisted migrations: the code compiles and runs successfully most of the time, but bugs surface with specific data that exposes semantic mismatches between how Objective-C and Swift handle runtime behavior.
