IOS App Maintenance Freelancer

@durgesh8527

Being an independent iOS developer with deep expertise in both older Objective-C and newer Swift modules, I can confidently say that maintaining and enhancing mature iOS apps is my forte. For a decade now, I have built scalable, clean, and maintainable code with a strong focus on performance—exactly the qualities your project requires. Moreover, I am well-versed in the utilization of Xcode, TestFlight, and App Store Connect for app development and troubleshooting. My previous projects provided me with exposure to multiple DevOps practices including Git version control that guarantees well-documented code which resides in your private Git repository. Commitment is a key aspect of my work style; I understand the urgency of promptly addressing issues as they arise. When you open a ticket, you can count on receiving an acknowledgement within 24-48 hours.

Hi, You need a solo iOS developer on call for a mature ~10-year app: bug fixes, small features, and Apple updates — as needed, not full-time. I work independently in Swift and can navigate older Objective-C alongside newer modules. Comfortable with Xcode, TestFlight, App Store Connect, and clean Git commits. When you open a ticket I’ll reply within 24–48 hours, agree scope, then deliver: code + TestFlight build + short change log. Price: ₹12,500 per typical ticket (we’ll adjust if a change is larger once I see the repo). Best regards

I’m comfortable taking ownership of an established iOS codebase where the work is mostly diagnosis, compatibility fixes, and small feature updates rather than a rewrite. For each ticket, I’d first reproduce the issue, trace the affected Objective-C or Swift code, and make the smallest maintainable change needed. I’d also check for any related impact from newer iOS SDKs, deprecated APIs, permissions, signing, or App Store requirements so the fix does not introduce another problem later. My normal delivery flow would be: code update in your private Git repository, local/device testing, TestFlight build, and a short change log covering what changed and anything that should be monitored after release. I’m also comfortable working with mixed Objective-C/Swift projects, Xcode build settings, provisioning profiles, TestFlight, and App Store Connect. For urgent issues, I can review the ticket quickly and give you a clear scope before starting. Is the app currently building cleanly with the latest Xcode version, or are there already dependency/deprecation warnings that need attention?

You need a reliable solo iOS developer who can step into a mature codebase, understand both legacy Objective-C and newer Swift, and make focused fixes without destabilizing an app that has already been in production for years. I’m comfortable working in established mobile codebases, tracing bugs through existing architecture, and making incremental changes with minimal surface area. I’d review each ticket against the current app behavior, isolate the root cause, implement the smallest maintainable fix, then verify it through Xcode and TestFlight before handoff. I’m also comfortable with Git-based workflows, release builds, App Store requirements, and keeping concise change logs so every update is easy to audit later. For a long-running app like this, I’d prioritize backward compatibility and regression safety over unnecessary refactoring. Which iOS versions and Xcode version does the current project target, and roughly how much Objective-C rem

@diegovisiso

Hi — Diego Vinicius here from Brazil. I appreciate that you're looking for someone to genuinely maintain a mature app rather than rebuild it — a decade-old codebase running smoothly is worth respecting, and the right approach is careful, surgical fixes, not sweeping rewrites. What usually matters most here is diagnosing bugs correctly the first time, especially in a codebase spanning older Objective-C and newer Swift, where a fix in one layer can have unexpected effects in the other. The tricky part is often responsiveness — since work is unpredictable, being able to pick up a ticket quickly, understand context fast, and turn around a clean TestFlight build without breaking existing functionality is what makes the relationship work long-term. My approach would be to acknowledge tickets within your 24–48 hour window, review the relevant code (Objective-C or Swift) before touching anything, commit clearly commented fixes to your private repo, ship a TestFlight build, and include a concise change log so you always know exactly what changed and why. A few questions to scope this well: Q1 – Roughly how many tickets come up in a typical month? Q2 – Is the codebase mostly Swift now with legacy Objective-C modules, or a more even mix? Q3 – Any pending Apple requirement changes you're currently tracking? Happy to discuss further. Looking forward to hearing from you.

@danielc0710

The app’s ten-year history makes careful maintenance more important than simply rewriting existing code. I can work directly within the mature iOS codebase, tracing issues through older Objective-C and newer Swift modules, fixing bugs cleanly, and implementing small feature updates without unnecessary disruption. For each ticket, I’d review the existing implementation, reproduce and isolate the issue, make the smallest maintainable change, test it in Xcode, and provide the updated code through your private Git repository. I can also prepare the corresponding TestFlight build and a concise changelog so each change is easy to review and track. I understand the need for an as-needed workflow, including acknowledging tickets within 24–48 hours and agreeing on scope and timing before implementation. Is the current project already building successfully with the latest Xcode version, or would the initial task include updating compatibility first?

@halaa020

Hi, Your project caught my attention because maintaining a mature iOS app is very different from building something from scratch. I understand that the priority is "diagnosing issues quickly, making careful changes, and keeping the existing app stable". I can work directly with your existing codebase and handle bug fixes, troubleshooting, small feature improvements and maintenance while keeping the current architecture in mind. I’m comfortable working with: • Swift / Objective-C codebases • Xcode and iOS development • Git-based workflows • TestFlight builds and testing • Debugging crashes, UI issues and unexpected behavior • API and backend integration • Incremental feature updates without disrupting existing functionality For each ticket, I’d first reproduce and isolate the issue, make the smallest appropriate change, test it thoroughly, and provide a clear summary of what was changed. I understand the importance of being especially careful with a 10-year-old production app where seemingly small changes can have unexpected side effects. I’m also comfortable working asynchronously and following your ticket-based process with clear communication and updates. I’m interested in building a long-term working relationship where you have someone reliable to call whenever the app needs attention, rather than bringing in a new developer for every issue. I’m ready to review the existing codebase and start with the first ticket.

@anupk188

Hi, Your requirement caught my attention because maintaining a mature iOS application is quite different from building a new app from scratch. With a 10-year-old codebase, the real work is often understanding existing architecture, tracing issues carefully, and making changes without disrupting functionality that is already working. I work with production applications where ongoing maintenance, troubleshooting, incremental feature development and release management are part of the job. I'm comfortable working with Xcode, Swift, Objective-C codebases, Git, TestFlight and App Store Connect. I can work with the ticket-based approach you've described: - Acknowledge new requests within 24–48 hours - Investigate the existing code before proposing changes - Fix bugs or implement incremental enhancements - Commit clean, clearly documented code - Provide a TestFlight build for validation - Share a concise summary of what changed I'm also comfortable with an irregular workload. You don't need to manufacture work every month simply to maintain an engagement—I can step in when something actually needs attention. I'd suggest starting with one real bug or small enhancement. That gives both of us a practical way to evaluate the working relationship before considering anything longer term. Happy to discuss the current app architecture and the first issue you'd like addressed. Best, Anup
