About this gig

Is your Flutter or Swift app outdated, failing to build, or no longer compatible with the latest iOS and Android versions?


I will upgrade your existing mobile application, update outdated dependencies, and fix compatibility issues without rebuilding the app from scratch. Whether you are facing an Xcode build error, Gradle issue, CocoaPods failure, deprecated package, or SDK migration problem, I will provide a clean and reliable solution.


What I can help with:

  • Flutter SDK and Dart package upgrades
  • Swift, SwiftUI, and iOS SDK updates
  • Xcode build, archive, and code-signing errors
  • Gradle and Android SDK compatibility issues
  • CocoaPods and Swift Package Manager errors
  • Deprecated API and plugin replacement
  • Firebase dependency migration
  • Android and iOS release-build preparation
  • TestFlight and store submission support
  • Performance and stability improvements


Why choose my service?


I work with both Flutter and native Swift applications, allowing me to resolve cross-platform and iOS-specific issues efficiently. You will receive clean code, clear communication, complete source code, and a stable application ready for further testing or deployment.
