Hi there, I can handle ongoing feature development, bug fixing, API/backend integration issues, testing and code improvements while following your existing development and deployment workflow. I’m comfortable working with existing codebases, investigating root causes before implementing fixes, using Git branches/PRs and thoroughly testing related user flows before delivery. I can also provide consistent progress throughout each assignment and communicate blockers early, with availability during the required working days for discussions and task follow-up. A couple of questions I would like to clarify: What iOS technology is the existing application built with, Swift, SwiftUI, UIKit or a combination? Can you share the current project structure or a small sample task so I can understand the codebase and workflow? There are a few other details I’d like to discuss around the existing architecture, task assignment process, testing requirements, CI/CD workflow and PHP/Yii2 involvement, but due to Freelancer.com's character limit I can't cover everything here. Please open a chat with me so we can discuss the existing application, review the development workflow and confirm how I can best support the team long-term.

This is a strong fit for my experience maintaining and enhancing existing iOS products rather than starting from scratch. I have 10+ years in software development and have delivered 249+ projects, including native iOS applications with Swift, API integrations, authentication, payments, notifications, and complex user flows. I can share relevant App Store or GitHub examples through Freelancer. I’m available throughout five working days each week for task discussions, follow-up, and consistent progress. I’m comfortable joining an established Git workflow, working with branches and pull requests, and moving changes safely through Development, Staging, and Production using the existing CI/CD pipeline. For each batch, I’ll first reproduce the issue, trace the root cause across the iOS client and API, then implement a focused fix or feature. I’ll use XCTest and practical regression checks for the affected flows before submitting a PR. I can also investigate PHP/MySQL integration issues and make small Yii2/PHP changes when needed, with attention to Linux deployment behavior and backward compatibility. I’ll flag risky changes and blockers early, and can maintain the expected one-task-per-48-hours pace where the scope permits. Is the current iOS codebase primarily written in Swift, or does it also include Objective-C? Muhammad Saad

Your biggest risk is regression across an iOS app, Yii2 API, and three environments. For each batch, I’d reproduce the current behavior first, trace affected iOS flows and API responses, then keep the change focused and covered by relevant tests. For integration bugs, I’d compare the device request with Yii2 application logs before changing either side; that usually prevents treating a backend response issue as an iOS defect. Risky changes would be raised before implementation, with blockers communicated early through the existing Git/PR workflow. The five-day communication cadence, task-based delivery, and 48-hour progress expectation are clear. My closest related backend work is Aras using PHP and Python, though I won’t present that as Yii2-specific experience. Does your CI pipeline currently run iOS unit/UI tests, or only build and deploy?

HELLO, I HAVE SUCCESSFULLY WORKED ON SIMILAR iOS MAINTENANCE, ENHANCEMENT & LONG-TERM DEVELOPMENT PROJECTS AND CAN PRESENT RELEVANT WORK. I have 10 years of experience in Mobile App Development and have carefully read your requirements. I understand this is an existing production-focused iOS application, not a new build, so my approach will be to first understand the current codebase, architecture, API flow and CI/CD process before making changes. I can handle weekly feature batches, bug investigation, API issues, performance improvements and required iOS enhancements while maintaining existing functionality. I follow Git branches/PRs, test each change on relevant user flows, investigate root causes before fixing issues, and communicate blockers early so agreed timelines are maintained. Key Features & Modules: iOS maintenance, feature enhancements, bug fixing, API integration, PHP/Yii2 support, MySQL, Git/PRs, CI/CD, testing & performance optimization. Availability: Part-time, task-based collaboration with regular communication across five working days. I’m comfortable working with existing codebases and interested in a long-term collaboration where code quality and stability are prioritized. Thanks, Jitendra

Hello, Your description makes it clear this is about maintaining and evolving an existing iOS app with a PHP backend. The setup already has staged environments, CI/CD, and a Git workflow—so the focus should be on understanding the current codebase, working through issues methodically, and delivering tested changes without introducing regressions. I’ve done similar maintenance work on apps with established backends, where the real challenge wasn’t new features but keeping the moving parts stable during updates. The backend here looks straightforward (Yii2, MySQL on Linux), so the main unknowns will likely be the app’s edge cases and how the PHP logic interacts with iOS. I can work within the task-based batches and respect the delivery timelines. If there’s any backend tweaking needed, I’ll keep it minimal and focused. Thanks, Denis.

Hello, An existing pre production app needs a developer who can change one thing without quietly breaking three others, so my approach would be to understand the affected flow first, reproduce the issue, trace its API and state dependencies, then make the smallest reliable change rather than rewriting working code. For every assigned batch, I would work through a consistent cycle: reproduce or define the expected behavior, inspect the relevant iOS and API paths, implement the change, test the feature itself, then regression test the related user journeys. If the root cause reaches Yii2, MySQL, or an API response, I am comfortable tracing that side as well instead of treating every issue as an iOS problem. Your Git and CI/CD structure also fits how I prefer to work. Changes stay scoped, commits and pull requests remain reviewable, blockers are raised early, and risky architectural changes are discussed before implementation. That makes ongoing maintenance much safer as different task batches arrive. Feel free to have a look at my portfolio and previous work on my profile as well. Is the existing iOS application primarily Swift with UIKit, SwiftUI, or a mixture of both? And do you already have automated tests around the critical user flows? Have a nice day.
