Why AI-Migrated Code Compiles But Breaks in Production

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.
