I will fix ios push notification bugs, apns or fcm setup and crash issues, swift
Charles B
About this gig
Do your iOS push notification alerts fail silently, or is your app crashing after an update?
Ill diagnose and fix production issues in Swift (and mixed codebases), focusing on fast reproduction, clean fixes, and verified testing.
What I can fix
- Push notification not received (foreground/background), Notification fix end-to-end
- APNs setup issues (auth key/cert, environment mismatch)
- FCM iOS integration bugs (token refresh, delivery, payload handling)
- Device Token issue / registration callbacks not firing
- Crash fix for random crashes, Launch crash on startup
- TestFlight crash / crash after upload
- Xcode errors during archive/signing and Build archive failures
- Background modes configuration problems
- UI-related issues like SwiftUI crash or edge-case state crashes
- General iOS bugfix and Swift debugging using logs/crash reports
How I work
- Reproduce the issue (steps, logs, crash traces)
- Pinpoint root cause (APNs/FCM config, code path, threading, permissions, entitlements)
- Implement fix + test plan (simulator/device)
- Share changes clearly (what changed, why, and how to avoid regressions)
Message me before ordering if youre unsure which package fits.
