iOS Bug Fix & Publish

My flutter based iOS application is finished and runs smoothly on TestFlight, yet Apple keeps bouncing the binary for certification-related reasons. I’m looking for someone who can jump into the existing Xcode project, clear the code-signing cobwebs, resolve the deployment errors, and guide the build all the way through App Store approval.

Here’s the situation:
• The only show-stoppers I have are deployment issues—specifically App Store submission errors tied to certificates and entitlements.
• Core features, UI, and performance are already solid; no new functionality is needed, just the fixes that will let Apple say “Approved.”
• All assets, screenshots, and metadata are prepared in App Store Connect.

Deliverables
1. Update certificates/provisioning profiles and adjust any build settings or Info.plist entries that trigger rejection.
2. Produce a clean, archive-ready build in Xcode, then submit it to App Store Connect without errors.
3. Stay available for one review cycle to address any follow-up from Apple until the app goes live.

If you know your way around Xcode, certificates, and Apple’s review guidelines, this should be quick. Let’s get this app into the store.
