FAQ
Do you work with existing iOS apps or only new ones?
Yes. I work on both new iOS apps and existing codebases. I can add new features, fix bugs, improve performance, refactor architecture, or modernize UIKit apps to SwiftUI.
What do you need from me to get started?
To start smoothly, I usually need: A short description of your idea or problem Any designs or references (if available) Target users and region App Store account access (only when needed) If you’re unsure, just message me and I’ll guide you.
Do you provide post-launch support after the app is delivered?
Yes. I provide post-launch support to help you ensure the app runs smoothly after deployment. This includes fixing any minor issues, assisting with App Store updates, and helping you understand how to manage the project moving forward.
Can you maintain or update the app after the project is completed?
Absolutely. Many clients continue working with me for long-term maintenance, feature updates, performance improvements, and scaling their apps as their product grows.
Will you help with App Store submission and approval?
Yes. I assist with preparing the app for App Store submission, configuring certificates and provisioning profiles, and helping resolve any App Store review issues.
What if I want to add more features later?
No problem. Once your app is live, we can continue improving it with new features, integrations, or UI improvements as your product evolves.
Can you work with my existing codebase?
Yes. I regularly work with existing iOS projects. I can review your codebase, fix bugs, optimize performance, and implement new features.
