I have an existing iOS app in the store that now needs a round of improvements. The source is written in Swift and managed through a private Git repository; I’ll grant you access as soon as we start. I’d like you to review the current build, work with me to prioritise the required tweaks, then implement and test them so the next TestFlight submission runs smoothly and meets Apple’s guidelines. At this stage I’m open to adjustments across the interface, feature set and overall performance. If you notice small design refinements that could elevate the user experience, feel free to suggest them—I can supply current assets and brand colours on request. Deliverables • Updated Xcode project with clean, well-commented Swift • Fully tested build uploaded to TestFlight (iPhone and iPad) • Brief change log describing what was modified and why Please share links to any live apps or updates you have shipped recently, note any libraries or frameworks you prefer working with, and give me a realistic turnaround time so we can set the first milestone.

Hi there, I can certainly help you with this. Since the app is already live on the App Store, I'll first review the existing codebase, understand the current architecture, and prioritize the improvements with you before making any changes. That helps avoid unnecessary rework and keeps the next TestFlight release smooth. I'll work directly from your Git repository, implement the required UI, feature, and performance improvements, test everything thoroughly on iPhone and iPad, and upload a stable build to TestFlight along with a clear changelog of all updates. I have a few questions regarding the current issues, third-party libraries, and the features you want to improve. I would request we connect once so we can discuss everything in detail and plan the first milestone. Thanks, Rahul A.

Hey, it's great you're already using a private Git repo; that makes reviewing the current build and prioritising changes much cleaner. I'd start by pulling your latest branch, getting the app running locally, and then we can walk through the current state to map out the tweaks. The real challenge with existing apps is often making sure new features integrate without introducing regressions, especially across iPhone and iPad, but I'm used to thorough testing for that. Are there any specific areas of the app you're most keen to improve first?

I’ve built and shipped five Swift iOS apps to the App Store, including a recent update that passed TestFlight review first try—so this is right in my wheelhouse. I’ll clone your private repo, run the static analyzer, then triage issues in Xcode’s Issue Navigator before touching a line of code. Once we lock priorities, I’ll refactor the Swift codebase to remove retain cycles, update deprecated APIs, and enforce ARC compliance, then run UI tests on both iPhone and iPad simulators to catch layout drift or broken constraints. After that, I’ll push a clean commit to TestFlight with the updated build number and a short changelog. I can start immediately.

Hi, We will review your Swift codebase, prioritize the updates with you, and deliver a tested build to TestFlight for both iPhone and iPad. One thing we will do early is profile the app with Instruments to catch memory leaks or slow view loads before writing any new code. That way performance fixes ship alongside your feature tweaks. A couple of quick things to confirm: 1) Which iOS version is the current minimum deployment target? 2) Are there specific screens or flows you want prioritized first? The number quoted here is a starting estimate. The exact cost and timeline will be confirmed after we go through the full scope together. Looking forward to talking through the details. Faizan
