Hello, I can update your existing Objective-C + Swift 4 project to compile cleanly and run smoothly on the latest iOS version, ensuring it passes App Store review without regressions. I’ve worked on multiple legacy upgrade projects where apps were modernized from iOS 11/12 targets to iOS 16/17, resolving deprecated APIs, entitlements, and Xcode build warnings. My process will be: Update project settings and deployment target for the latest Xcode/iOS. Replace or refactor deprecated APIs and frameworks while preserving existing behavior. Handle permission dialogs, ATS requirements, and other compliance changes. Retest all screens on iPhone/iPad simulators plus a physical device. Generate an App Store–ready archive and provide a concise change log. Supply updated source code with a short “how to reproduce” test sheet for verification. Acceptance criteria met: Clean build in the latest Xcode. Stable runtime on iOS 17 (or current release). No feature regressions. Documentation for smooth hand-off. I have recent experience bridging Objective-C with Swift 5 and ensuring older apps remain compatible with Apple’s latest requirements. I can give you a reliable turnaround and clear communication at every step. Best regards, Najir
