FAQ

Questions about iOS development.

How much does an iOS app cost?

Most iOS MVPs cost $25,000–$60,000 depending on features, integrations and design. A discovery phase gives you a precise estimate.

Should I build native or cross-platform?

Native Swift is best for premium, iPhone-first products or heavy use of Apple features. If you need iOS and Android on one budget, cross-platform is often better.

Do you publish to the App Store?

Yes — we prepare the listing, handle review and set up phased releases.

Which iOS versions do you support?

Usually the last two major iOS versions, which covers the vast majority of active iPhones.

Can you update my existing app?

Yes, including Swift and SwiftUI migrations, crash fixes and new features.

What language is used for iOS app development?

Native iOS apps are built in Swift, usually with SwiftUI for the interface. Perpetio uses Swift and SwiftUI with Xcode, TestFlight and Firebase to build, test and release iPhone and iPad apps.

How long does it take to build an iOS app?

A focused iOS MVP usually takes 8–12 weeks from discovery to App Store release. Larger apps are delivered in phases, with a working TestFlight build every two weeks.
