Hi, I have experience debugging React Native / Expo applications that work correctly on stable iOS versions but fail on new iOS beta releases due to native module, CocoaPods, Expo SDK, or React Native compatibility issues. I have 9+ years of mobile development experience and am comfortable working with React Native bare workflow, Expo SDK, Xcode, CocoaPods, native iOS code (Swift/Objective-C), TestFlight, and App Store deployment. From your description, my first step would be analyzing the crash logs and identifying which native module or iOS 26 compatibility change is triggering the launch failure. After isolating the issue, I can implement and test a fix while keeping compatibility with iOS 17/18. I can start immediately and help get the app stable on iOS 26. Thank you.

Hello there, I will diagnose and fix the iOS 26 launch crash — reviewing native crash logs, identifying the breaking API changes, and patching the affected native modules to restore stability on the beta runtime. Since you are on JSC with SDK 54, I will check UIKit lifecycle changes in iOS 26 that affect JavaScriptCore initialization — a common source of launch crashes on this beta. Questions: 1) Do you have the iOS 26 crash log from Xcode Cloud or device console? 2) Which native modules required patches so far? This bid is an initial estimate — I will confirm the final cost and timeline once we have walked through the complete requirements together. Ready to start whenever you are. Kamran

Hi, A launch crash that only hits iOS 26 beta on a build that's fine on iOS 17/18 usually traces to one native frame: a CocoaPod or a JSC initialization call the new SDK changed under you. First move is the symbolicated crash log from the tester's device. The top non-system frame tells us whether it's a pod, your JSC (JavaScriptCore) engine setup, or one of the iOS 26 compatibility patches conflicting with each other. How I'd approach it: - Pull the crash log, symbolicate it, isolate the failing native frame - Patch the offending node_modules native code with patch-package so the fix survives reinstalls - Re-run through Xcode Cloud to confirm against the beta device I work in React Native bare workflow plus Expo daily and do exactly this kind of native debugging across CocoaPods and Swift/Obj-C. It's most of what my 72 reviews are built on. Have you been able to grab a full symbolicated crash log yet, or just the launch crash report TestFlight surfaces? Asif

Hi, this looks like a narrow iOS launch-failure investigation in an otherwise working Expo/React Native app, which is the right kind of problem to handle surgically rather than by rewriting pieces blindly. The real engineering risk is early app bootstrap on the new iOS beta, where one native dependency or initialization side effect can crash before useful telemetry is available. I’ve worked on live products where the first step is isolating the failing startup boundary, then reducing the issue to one reproducible path. In your case, the useful detail is that the app is stable on iOS 17/18 and the Xcode Cloud pipeline is already healthy, which usually means the problem sits in runtime compatibility rather than general build integrity. The closest relevant work on my side is Custom Feature Development & Integration, where I stepped into an existing codebase, reviewed implementation boundaries, and made targeted fixes without destabilizing the rest of the product. I also have strong bug-localization experience from my code analysis work, which is the same discipline needed here. I usually structure this by separating bootstrap analysis, native dependency review, and runtime feature gating so the crash source is narrowed quickly. If useful, I can review the startup path and map the most likely failure points before patching. Thanks, Hercules

Hi, This sounds like a focused debugging and iOS compatibility project rather than a full application build, which is exactly the type of issue I enjoy tackling. I have experience working with React Native, Expo, CocoaPods, Xcode, native iOS integrations, build pipelines, and production app troubleshooting. Since the application is already feature complete and functioning on iOS 17/18, my priority would be identifying the root cause of the iOS 26 launch crash through crash logs, Xcode diagnostics, dependency analysis, and native module inspection. I am comfortable investigating React Native and Expo compatibility issues, reviewing CocoaPods dependencies, patching native code when required, validating third party SDK compatibility, and testing fixes across multiple iOS versions. I can also review the recent compatibility patches already applied to avoid duplicate efforts and isolate any remaining breaking changes introduced by iOS 26. The goal would be to deliver a stable build that launches correctly on iOS 26 while preserving compatibility with existing supported versions and your current Xcode Cloud workflow. Best, Justin

I’m guessing the tricky part here isn’t React Native itself anymore—the app is already feature-complete and running on iOS 17/18. The real job is finding what iOS 26 beta changed that causes the launch crash and isolating whether it’s coming from Expo, a native dependency, or custom patched code in node_modules. My first step would be reproducing the crash locally on an iOS 26 simulator/device, then working backwards through the crash logs and startup sequence to identify the exact native module failing during initialization. From there I’d compare dependency compatibility, inspect any existing patches, and verify CocoaPods, Expo SDK 54, and JSC-related integrations against the current beta behavior. Once the root cause is confirmed, I’d patch and validate it through a clean Xcode Cloud build and TestFlight round. I recently worked on React-based production applications where debugging framework-level issues required patching dependencies rather than app code, so I’m comfortable digging below the JavaScript layer when needed. Do you already have the latest iOS 26 crash logs from the affected tester, and is the crash occurring before the first screen renders or immediately after app initialization begins?

Hello, I reviewed your Tzedakapp issue and I understand the core challenge is not feature development, but stabilizing an already production-ready React Native app that is crashing specifically on iOS 26 beta. I can help you debug and fix this by carefully analyzing crash logs, identifying compatibility breaks in React Native 0.81 / Expo SDK 54, and patching any native iOS issues in CocoaPods, JSC, or node_modules dependencies. I have experience working with React Native bare workflow, Xcode Cloud CI, and iOS native debugging (Swift/Objective-C), which is essential for resolving beta OS-level issues. My approach will be to first isolate the crash root cause, then apply targeted fixes while ensuring existing functionality remains intact across iOS 17/18. I will also verify stability through clean builds and device testing. I’m available to start immediately and help you bring the app back to stable launch on iOS 26.

Hello, Tzedakapp sounds realistically fixable: the app is already feature-complete, stable on iOS 17/18, and the issue is isolated to launch failure on the current iOS 26 beta. I can step into the existing React Native 0.81 / Expo SDK 54 bare workflow setup and focus on diagnosing the native crash rather than rebuilding anything unnecessary. My approach would be to review the TestFlight/Xcode crash logs, symbolicated stack trace, Pod configuration, Expo modules, and any node_modules native patches already applied. I’m comfortable working with React Native, Expo, TypeScript, CocoaPods, Xcode, Swift/Objective-C native code, and CI builds, so I can trace whether the failure is coming from an iOS 26 beta API/runtime change, JSC behavior, a dependency, permissions, push notification setup, or a native module initialization issue. For this scope, I’d suggest a focused troubleshooting budget of $220 and an initial 3-day timeline, including diagnosis, patching, a clean iOS build, and notes on what changed so your team can maintain it through future iOS beta updates. I can start anytime and work full-time. I look forward to working with you. Regards, Osama

Hey — saw your post about troubleshooting the Tzedakapp React Native/Expo iOS app. The biggest pain point with Expo apps on iOS usually revolves around build config or permission setups causing unexpected crashes or failures. Quick question: Are you using managed Expo workflow or a bare workflow for this app? I’ve debugged several React Native apps with complex permissions and iOS-specific issues, so I know where things tend to break. If you share your current error logs or project files, I can take a look and help identify what’s causing the problem.

Hi — read through your post. The iOS 26 launch crash on a RN 0.81 / Expo SDK 54 bare workflow build with Supabase + JSC and EFI Bank PIX is the kind of thing I'd dig into pragmatically: pull the symbolicated crash log from Xcode Cloud or the tester's device, narrow whether it's a Hermes/JSC mismatch, a CocoaPods native module breaking against iOS 26 SDK changes (most often something in the keychain/SafeArea/Permissions chain), or a runtime API removal hitting node_modules. My plan: reproduce on an iOS 26 sim/device, isolate the offending pod or patched native bridge, apply a minimal fix (patch-package or a podspec pin), validate on TestFlight build pipeline, then hand back a short note on what broke and why so future iOS betas don't catch you again. We've shipped React Native apps with Supabase backends and run Xcode Cloud CI, so the stack is familiar end-to-end. Ping me with the crash log + last working TestFlight build and I'll come back with a tighter ETA. — Rohan, APIE TECH
