Send me a text 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 Check out Do iOS, the iOS development conference I'm organizing later this year.

Send me a text Make sure to let me know what you think of this episode. I completely refactored an audio system for a work app, splitting a single AVAudioEngine into separate engines for recording and playback. This architectural change fixed a bizarre bug where the system volume slider moved unexpectedly during audio operations. • Split AVAudioEngine into separate recording and playback engines • Fixed the MP Volume View movement issue by unifying audio session management • Improved background task management for location tracking services • Removed dead code and deprecated functionality • Explored solutions for audio session conflicts, threading issues, and memory leaks • Implemented dedicated dispatch queues for different audio operations • Created a robust background task management system for location updates • Added extensive logging to better understand audio session lifecycles Looking ahead to SwiftUI integration, audio performance optimization, and iOS 26 compatibility testing.

Send us a Text Message. Shaun took me up on a request on Mastodon to come on my podcast. We had a great conversation about how he ventured into management as a software developer. We also talk about how he got into software and iOS app development. Shaun took the React route. Start with web development, get started with React, progress into React native and then making the leap into native app development. Ray Wenderlich, now called Kodeco was instrumental in learning about iOS app development.

Send us a Text Message. I've been scheduling a few interviews again. It's interesting to see that people are often quite self-deprecating about being a good candidate to be interviewed on my podcast. People can always indicate why they are not exciting guests, but let's start at the opposite end. Think about why you would be a good guest for my podcast. And I notice that a lot. People often start with the negative. Why not start with the positive, I wonder?
