iOS development process breakdown
A transparent, repeatable process refined across 50+ iOS projects. You always know what's happening and why.
Discovery & Strategy
User research, platform requirements analysis, technical feasibility assessment, and architecture planning — defining your iOS app before we write code.
UX & iOS Design
User flows, wireframes, and pixel-perfect iOS designs that follow Apple's HIG — including gestures, navigation, and platform-specific patterns.
Swift Development
Agile sprints with bi-weekly demos. We build your iOS app with clean architecture, comprehensive testing, and a TestFlight beta available from week one.
QA & Testing
Device-specific testing, performance profiling, crash analytics, memory leak detection, and App Store compliance checks. Zero critical bugs to production.
App Store Submission
We handle the entire App Store submission process — prepare metadata, screenshots, app previews, and respond to Apple's review team. You get your app in users' hands, worry-free.
Ongoing Support
Flexible retainer agreements for maintenance, iOS updates, feature development, and performance monitoring. We become your long-term iOS engineering partner.
Our stack
iOS technologies we use
We leverage Apple's ecosystem and the best Swift tools — from frameworks to backend integration.
iOS app development costs depend on complexity and features. A standard consumer app typically ranges from $30,000–$80,000. A complex enterprise app with custom integrations can range from $80,000–$250,000+. We provide a detailed fixed-price estimate after a free 1-hour discovery call — no obligations.
It depends on your project. SwiftUI is great for new apps that want to leverage the latest iOS features and write less code. UIKit is better for complex, custom interfaces or when you need broad iOS version support. We help you choose the right approach based on your requirements.
A standard iOS app typically takes 10–20 weeks. A simple MVP can be delivered in 8–12 weeks. We work in agile sprints and deliver a TestFlight beta version within the first 6–8 weeks, so you can start testing and gathering feedback early.
Yes — we manage the entire App Store submission process, including preparing metadata, screenshots, app previews, and responding to Apple's review team. We have a 99% first-time approval rate across all our iOS projects.
Yes — we build universal iOS apps that work seamlessly on both iPhone and iPad. We also handle iPad-specific features like split view, drag and drop, and Apple Pencil support when needed.
