AppForce1 Worklog: Refactoring an 8-Year-Old iOS App is Like Restoring a Classic Car
Manage episode 509074848 series 2812161
Jeroen shares his real-world iOS development journey working on a legacy app at Dawn Technologies. He details his systematic approach to modernizing an 8-year-old codebase that serves as a critical tool for companies.
• Breaking down a monolithic App Delegate into dedicated managers with single responsibilities
• Leveraging the existing feature flag system to safely deploy new implementations
• Refactoring the walkie-talkie functionality with real-time audio streaming over WebSockets
• Completely rewriting the chat system to use a modern service-based architecture
• Overhauling the location tracking system to use iOS 17's new async location tracking APIs
• Implementing WiFi settings fixes for iOS 16 compatibility using modern APIs
• Maintaining a cleanup branch to remove deprecated APIs and fix compiler warnings
