FAQ
What information should I provide when ordering?
Please send me: • A short description of the issue • Steps to reproduce (if possible) • A sample project or access to the affected code (zip file or GitHub link) • Target iOS/macOS version and Xcode version
Do you work with SwiftUI, UIKit, or Objective-C projects?
Yes, I support all of them — including mixed Swift/Obj-C codebases. I also have experience in modern SwiftUI app structures and legacy UIKit projects.
What if I don’t have reproducible steps or logs?
That’s okay — I can investigate based on the symptoms or screenshots, and I’ll try to reproduce the issue. In the Premium package, full diagnostic work is included.
Will the fix be production-ready?
Absolutely. All fixes are made following best practices and tested locally. If you choose the Premium package, I also include unit tests and full documentation of changes.
Do you help with App Store rejection bugs?
Yes, I can help analyze and fix bugs causing rejection (e.g., crashes, UI bugs, unexpected behaviors). Please attach the rejection message when contacting me.
Can I request additional fixes after delivery?
Minor revisions are included based on the package. For unrelated or new issues, you can purchase the “Additional Bug” extra, or we can set up a custom offer.
