iPhone App Crash Debugging

My production-ready iOS app has started crashing at random points during normal use. Users report it happens a few times each week, but never during launch or sign-in, so the issue is buried somewhere in the day-to-day workflow. I need a seasoned iOS developer who can comb through the existing Swift codebase, analyse the crash logs (I can provide Crashlytics reports), reproduce the fault, and deliver a stable build that eliminates these bugs.

The app is already live on the App Store, so the fix must be surgical—no sweeping rewrites, just precise debugging and patches that maintain current functionality and design.

Deliverables:
• Isolated root cause with annotated code changes
• Patched Xcode project plus TestFlight build for verification
• A short report outlining the fix and steps to avoid regressions

Acceptance will be based on a two-week period in which our internal testers can no longer reproduce the random crash under normal usage patterns.

If you are comfortable diving deep into Swift, Instruments, and Crashlytics to track down elusive race conditions or memory issues, I’d love to hear how quickly you can turn this around.
