Stack Trace

Crash occurs in UIGestureEnvironment touch delivery during gesture recognizer state transitions.

Investigation Steps

1. Gesture Handling Code Review

   • Audit touch event handling implementation
   • Review gesture recognizer delegates and state management
   • Check for proper cleanup during cancellation

2. Memory Management

   • Investigate memory pressure scenarios in touch event processing
   • Review object retention/release patterns in gesture handling
   • Check for potential memory leaks in UIKit integration layer

3. UIKit Integration

   • Verify proper UIKit API usage patterns
   • Review any custom gesture recognizer implementations
   • Check for threading issues in touch event processing
