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. Do iOS 2025 is happening November 11-13 at NEMO Science Museum in Amsterdam - check out do-ios.com for more information.
