FAQ

iOS Development — Common Questions

A simple iOS app starts from $25,000. A mid-complexity app with backend, Apple Pay and third-party integrations runs $45,000–$90,000. Complex marketplace or healthcare apps range from $100,000–$250,000+. We provide a fixed-price estimate after a free 30-minute discovery call.
All new projects use Swift (currently 5.9) with SwiftUI for the UI layer. Swift is faster, safer and Apple's primary language for all new frameworks. We can maintain and incrementally migrate existing Objective-C codebases to Swift without a disruptive full rewrite.
We have a 100% App Store approval rate across 400+ submissions. We follow Apple's Human Interface Guidelines and App Store Review Guidelines throughout development, not just at submission — which eliminates the surprises that cause rejections.
Yes — SwiftUI enables truly universal apps from a single codebase with device-specific layouts. We design and test on iPhone, iPad (all sizes), Apple Watch and can extend to macOS via Catalyst or Apple Vision Pro via visionOS.
We typically support iOS 16+ as the minimum, covering 95%+ of active iPhones. If your audience includes enterprise users on managed devices, we can adjust the minimum version. We always target the latest Xcode and iOS SDK to access new APIs and maintain App Store compliance.
We use Mac hardware with Xcode — Apple's requirement for iOS development and App Store submission. You don't need to own a Mac yourself; we handle all of that. We provide you with build files, TestFlight beta links and regular demo sessions accessible from any device.
