The mobile app is already 100 % coded for both iOS and Android, yet the iOS build still refuses to behave. I need an expert who can dive into the existing project, diagnose what is blocking a smooth run on current iPhones and iPads, and deliver a clean, crash-free build ready for TestFlight and App Store submission. Here is what you will be tackling: • clone the private repo, review the current mobile codebase and identify the iOS-specific issues • fix crashes, layout glitches, and any API or permission problems that keep the app from passing Apple’s review • run thorough device testing on recent iOS versions and document every fix • push the corrected code back to the repo and provide a concise hand-over note so I can keep the project healthy moving forward The Android side is already live, so use it as a reference while keeping parity between both platforms. Access to all design assets, backend endpoints, and my existing bug list will be shared as soon as we start. Once the iOS build runs flawlessly and is accepted by Apple, the job is done.

Hi, I went through your requirement and it’s clear the app is fully built, with Android already live, but the iOS version is facing stability and compliance issues. You’re essentially looking for someone to audit the existing codebase, resolve crashes, fix UI/permission gaps, and get it App Store–ready with proper testing and documentation. I’ve handled similar cases where near-complete apps failed on iOS due to version compatibility, entitlement issues, or subtle layout bugs, and successfully pushed them through TestFlight and approval. A few quick questions: – Is the app built in Flutter, React Native, or native Swift? – Are there any crash logs or TestFlight feedback already available? – Any third-party SDKs (payments, analytics) involved? Approach: deep code audit → isolate iOS-specific issues → fix + device testing → TestFlight validation → submission support. Happy to discuss further.

Hi, This is Elias from Miami. I checked your project description and understand you need an experienced developer to review the existing iOS code, diagnose crashes and layout issues, and deliver a stable build ready for TestFlight and App Store approval while keeping parity with the live Android version. I would approach this by cloning the repo, comparing Android vs iOS behavior, fixing crash logs and permission issues, testing on recent devices, then preparing a clean submission build. I’ve worked on several apps where Android was stable but iOS required debugging and App Store compliance fixes. I’d be happy to go through the details and suggest the best technical approach. I have a few questions to get a better understanding: Q1 – Is the app built with Flutter/React Native or fully native Swift so I know where the iOS-specific issues likely originate? Q2 – Are you currently seeing crashes at launch, during API calls, or related to permissions/background tasks? Q3 – Do you already have Apple developer account access and certificates set up for TestFlight submission? Looking forward to hearing from you.

Hello, Getting your iOS app ready when Android is already live can be tricky due to build issues, outdated libraries, or Apple’s strict rules. I will fix these problems, make your app stable, and ensure it works just like your Android version so you can successfully submit it to the App Store. My process involves auditing build logs for linker errors, aligning permissions with current Apple standards, and polishing layout glitches for recent iPhone and iPad aspect ratios. I'll provide a clean repo push and a concise health note to ensure the project stays stable long-term. Are the failures happening during local Xcode builds, or are these crashes occurring specifically within TestFlight? Best, Niral

Hi there, I can understand sometimes iOS builds behave unexpectedly even when everything looks fine, and I’ve faced similar issues before where apps were working on Android but had crashes, permission issues, or layout problems on iOS, which I later fixed and successfully deployed to the App Store which you can verify from my profile. I can help you review your existing codebase, identify the exact issues causing crashes or rejections, and fix them to make the app stable and ready for TestFlight and App Store submission while keeping parity with Android. Once you share your repo access and current bug list, I can quickly audit and start resolving the issues. Thanks, Rahul A.

Hello, I understand you have a fully coded mobile app for iOS and Android but the iOS version still has issues causing crashes and layout problems. I will start by cloning your private repo and exploring the iOS code to find the key problems. Then, I will carefully fix crashes, layout glitches, API connections, and permission issues to make sure the app passes Apple’s review smoothly. I’ll test thoroughly on different recent iPhones and iPads to confirm it runs perfectly. After fixing, I will push clean code back to the repo and give you clear notes so you can maintain the app well. I will also use the live Android app as a guide to keep features consistent on both platforms, ensuring a reliable, user-friendly experience. Are there any specific iOS versions or devices you want me to focus on for testing? Can you share the current list of bugs you have noticed in the iOS app? Is there any part of the app that uses unusual or custom APIs that might need special attention? Do you have any existing automated or manual test scripts I can use to verify the fixes? What access details will I receive for the private repo and backend to work effectively? Best regards,

Hi, This is really an iOS stabilization and release-readiness job, not a general mobile build task. The real goal is to make the existing app behave predictably on current iPhones and iPads, pass Apple’s review requirements, and leave the project in a state where the next release does not reopen the same issues. The usual failure point here is not one single crash. It is a mix of iOS-specific runtime behavior, permission flow, signing/config mismatches, layout edge cases, and API assumptions that worked on Android but break under Apple’s rules or device patterns. I’d approach this by auditing the native iOS layer, tracing the highest-risk crash and review paths first, then fixing parity issues without forcing Android logic onto iOS where it does not belong. I’d start with the crash path, permission/config audit, and App Store blocker review before touching lower-priority UI issues.

Hi, I’m Abhishek Rathore, a senior mobile engineer, and I understand you have a fully built app where the iOS version fails to run cleanly despite Android being live. I’ll step in to diagnose the iOS-specific blockers and deliver a stable, App Store-ready build. ? Approach I’ll start by cloning your repo and running the project in the latest Xcode with real devices. I’ll trace crashes via Xcode debugger and device logs, audit iOS-specific layers (Swift/Obj-C, CocoaPods/SPM), and compare behavior with Android APIs to isolate mismatches. ✅ Core Features • Fix runtime crashes and memory/threading issues • Resolve layout/autolayout glitches across iPhone/iPad • Validate API calls, auth flows, and network handling • Correct permission handling (camera, notifications, etc.) • Ensure App Store compliance (signing, plist, policies) • Maintain parity with Android behavior ☁️ Reliability / Performance I’ll test on multiple iOS versions (16–18), handle edge cases like background states and network loss, and ensure stable builds with proper provisioning and TestFlight configs. ? Deliverables • Clean, crash-free iOS build • Updated repo with fixes • TestFlight-ready package • Concise handover notes with key changes ? Why Me I’ve debugged and shipped similar recovery-stage apps where Android was stable but iOS needed deep fixes. Quick question: is the project using Swift + CocoaPods or SPM for dependencies?

Hi I can step into your existing mobile codebase, isolate the iOS-specific issues, and turn the current app into a stable, TestFlight-ready build without disrupting Android parity. The main challenge here is that “100% coded” cross-platform apps often fail on iOS because of signing, permissions, API behavior, layout constraints, background/lifecycle handling, or Apple compliance details, so I would solve that with a structured audit and targeted fixes rather than broad rewrites. My approach would be to clone the repo, compare iOS behavior against the live Android reference, reproduce crashes/layout bugs on current iPhones and iPads, fix the root causes, and validate the app against App Store review requirements. I have experience debugging production mobile apps, resolving iOS-specific build/runtime issues, and preparing apps for TestFlight and App Store submission. You’ll receive the corrected code pushed back to the repo, documented fixes, and a concise handover note so the iOS side stays maintainable after launch. And I can help you so on by getting the iOS build clean, stable, and submission-ready instead of just partially patched. Thanks, Hercules
