My production iOS app has a few sections where the behaviour simply isn’t what the user expects. The interface loads fine and performance is acceptable, but logic-level bugs are causing incorrect functionality and I need them resolved quickly. What I need from you: • Analyse the current Objective-C/Swift codebase, reproduce the faulty flows, and pinpoint the root cause of the incorrect behaviour. • Implement clean, well-documented fixes that restore the intended logic without introducing regressions. • Build and run unit or UI tests that prove the fix works on the latest iOS version. • Supply the updated Xcode project plus a concise changelog so I can review and submit the next App Store build. You should be comfortable with Xcode, Git, and TestFlight so we can iterate fast. If you’ve recently navigated App Store submission guidelines, that’s a bonus. Let me know your estimated turnaround and any similar troubleshooting work you’ve completed.

Hello, We can help diagnose and resolve the logic-level issues in your production iOS application. Our approach would be to first reproduce each faulty flow, trace the relevant Objective-C/Swift logic, identify the actual root cause, and then implement focused fixes without unnecessarily changing the existing application architecture. The workflow would include: Codebase and issue analysis Reproduction of faulty user flows Root-cause debugging in Xcode Clean Swift/Objective-C fixes Unit/UI regression testing Testing on the latest supported iOS version Git-based development and change tracking Updated Xcode project and concise changelog We understand that this is a production application, so stability and avoiding regressions are our priority. Once we understand the number and complexity of the affected flows, we can provide a realistic turnaround and milestone plan. I'd be happy to review the existing issue details and codebase and get started quickly. Best regards, Bivanshi Ohri

Good day! Logic-related issues can be some of the most frustrating bugs in an iOS application because the interface appears to work while the underlying behavior produces unexpected results. My first priority would be to reproduce each faulty workflow and trace the problem directly within the existing codebase rather than applying temporary fixes. I'll carefully analyze the Objective-C and Swift components, identify the root cause of each issue, and implement clean, maintainable fixes that preserve the current application structure. Particular attention will be given to preventing regressions, especially in areas where multiple features share the same business logic. I'll also validate the changes with appropriate unit or UI testing, provide an updated Xcode project, and include a concise changelog that clearly documents every modification. I'm comfortable working with Xcode, Git, and TestFlight, which will help keep the debugging and review process efficient.

Hi, The issue sounds like classic logic bugs where the app does what the code says rather than what the user expects. I’ve debugged similar flows in native iOS apps before, particularly around state mismatches between view controllers and network responses. Back when I updated parts of the CoastPay iOS client, the main challenge was tracing how the UI state drifted after a background API call completed. The fix involved tightening the state machine between the view controller and the network layer, then adding a few targeted integration tests to catch regressions. I’d start by reproducing the faulty flows in the simulator, attach LLDB to the relevant view controllers, and map where the state diverges from the expected path. Once the root cause is clear, I’d patch the logic, add unit or UI tests that cover the exact sequence that failed, and verify the fix on the latest iOS version before handing back the Xcode project and changelog. The main unknown is whether the bug is in the view layer, the networking layer, or somewhere in between. A quick debug session will tell us which part needs attention without overbuilding. Thanks, Denis.

Hi there! The main issue is not UI or performance, but logic-level bugs that are affecting expected user flows in your production iOS app. These need careful debugging so the fixes do not create new regressions. I have experience with Swift, Objective-C, Xcode, Git, iOS debugging, unit testing, and UI testing. I can work through the existing codebase, reproduce the faulty flows, identify the actual root causes, and apply focused fixes. I will first reproduce each issue and trace the related logic in the Objective-C/Swift code. Then I will implement clean fixes while keeping the existing architecture stable. I will add or update tests to verify the corrected behavior on the latest iOS version. Finally, I will provide the updated Xcode project and a concise changelog ready for your review and TestFlight/App Store process. For a focused bug-fixing task, I can start immediately and provide an initial diagnosis quickly after reviewing the project. check our work https://www.freelancer.com/u/ayesha86664 Can you share the list of faulty flows and the current Xcode project so I can estimate the turnaround accurately? Let me know if you’re interested & we can discuss it. Best Regards Ayesha

Production iOS bug fixes on logic-level issues — reproduce the faulty flows, find actual root cause instead of patching symptoms, ship clean fixes with tests proving the behavior is corrected. Xcode, Git, TestFlight workflow is standard for me, and I've handled recent App Store submission guideline changes so nothing catches you by surprise on the next build. My approach on logic bugs: reproduce first, always. If I can't reliably trigger the issue with the exact user flow, I don't trust any fix I write. Once reproducible, I trace the code path in the debugger and confirm which piece of state or which branch is wrong — not just where the symptom shows up (which is usually a few layers above where the bug actually lives). This is the difference between fixes that hold and fixes that come back three sprints later. Comfortable across Objective-C and Swift, including mixed codebases where a Swift screen calls into an older Obj-C model layer or vice versa

Hello, As a result of a detailed review of your requirements, I understand you need focused troubleshooting of logic-level issues in an existing production iOS app rather than a UI rebuild. I have experience with Swift, Objective-C, Xcode, Git, iOS debugging, unit/UI testing, TestFlight, and production app maintenance, and I’m available to start immediately. I would first reproduce each faulty flow, trace the affected state/data logic, and isolate the root cause before changing code. The fixes will be kept minimal and well documented, followed by regression testing on the latest iOS version and validation through Xcode tests and TestFlight where needed. The main priority is correcting the current behaviour without disturbing stable parts of the app. For similar troubleshooting work, I’ve handled issues involving navigation state, asynchronous API responses, persistence, validation logic, and incorrect UI state updates after user actions. Turnaround will depend on the number and complexity of bugs, but I can provide an initial diagnosis quickly after reviewing the project. A couple of quick questions: • Roughly how many faulty flows are currently known? • Can you provide the Xcode project, reproduction steps, and any crash/log output available? Best regards, Carlos

Hi there, Could you share which user flows are currently producing the incorrect behaviour? Based on your project, we understand you need the existing iOS app investigated at code level, with the faulty flows reproduced and their actual causes identified. We are a UK-based development agency experienced in iOS apps, debugging, API integration, and ongoing product support. We’ll first reproduce each issue and trace the related code paths to identify where the expected behaviour breaks. After isolating the cause, we’ll apply focused fixes and test the affected flows against existing functionality. We’ll then run the required tests, verify the build, and provide the updated project with a short changelog. Questions: 1) Which sections of the app currently have the most serious bugs? 2) How are the current bugs being discovered and reported? Budget and timeline are flexible. Let’s connect via chat or a quick call to finalize the details and get started! Cheers, Darian.C From Red Feather Solutions

Hello, I’ve worked on iOS debugging tasks where the UI was fine but underlying logic, state handling, or API flows caused unexpected behavior. I understand the importance of finding the real root cause instead of applying quick fixes that create new issues later. Can you share whether the bugs are mainly related to app state, networking/data handling, or specific user flows? I’d start by reproducing each issue in Xcode, trace the affected code paths, and apply focused fixes with proper testing. I’ll also verify the changes on the latest iOS version and provide a clear summary of what was changed so your next TestFlight/App Store build is easier to review. Happy to take a look at the current project details. Abel
