Our Process

Our iOS App Development Process

01

Discovery & Spec

We deep-dive into your product goals, target users, and technical requirements to define a clear specification, architecture plan, and project roadmap.

02

Design & Prototype

Our designers create high-fidelity Figma prototypes with interactive flows, ensuring the UX is validated before a single line of Swift is written.

03

Swift Development

Our engineers build your app using modern Swift and SwiftUI, with clean architecture (MVVM/TCA), thorough unit testing, and continuous integration via Xcode Cloud.

04

App Store Launch

We handle App Store Connect setup, TestFlight beta testing, App Review submission, and post-launch monitoring to ensure a successful and stable release.

FAQ

iOS App Development
FAQ.

Everything you need to know about our iOS app development services.

Ask Us Anything

We 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.
