Depends on team size. With larger team the technical debt turned into a positive feedback loop. Not good. Cyclomatic complexity increased. Methods became a black box. A junior coder would copy and paste a method and change one parameter to make it work for a new context. Nearly identical methods would proliferate. Milestones would slip. Here's how I dealt with each: 1) reduced the internal team to half its size 2) fired the offshore team and started from scratch 3) personally attempted a mass refactor / 90 hour weeks 4) refactored 49K line C++/ObjC++ to 29K Swift Result of each: 1) product shipped, became industry standard 2) Speed improved, Apple offered to feature product 3) I failed, resigned after burnout 4) Easy and enjoyable refactoring to SwiftUI
