Everything you need to know about our iOS app development services.
Ask our teamWe exclusively use Swift for all new iOS projects. Swift is Apple's modern, safe, and expressive language with significantly better performance and tooling than Objective-C. If you have an existing Objective-C codebase, we can incrementally migrate it to Swift.
Common rejection reasons include guideline violations around in-app purchases, privacy permissions without proper justifications, incomplete functionality, and misleading metadata. We review every submission against the latest App Store Review Guidelines before submitting, dramatically reducing rejection risk.
A typical iOS app with standard features takes 10–14 weeks from kickoff to App Store approval. Simple apps can be delivered in 6–8 weeks, while complex apps with custom backends, real-time features, or hardware integrations may take 16–24 weeks.
For new projects targeting iOS 16+, we recommend SwiftUI for its declarative syntax, live previews, and rapid iteration. For apps requiring support for older iOS versions or complex custom UI, UIKit remains a strong choice. Many of our projects use both together.
Yes. We offer flexible post-launch support packages covering bug fixes, iOS version compatibility updates, performance monitoring, and feature enhancements. Most clients engage us on a monthly retainer to keep their app healthy and evolving.
