Core audience is on iPhone
The product's paying customers mostly use iOS, and that is where revenue comes from.
Swift
Apple's programming language for iOS, iPadOS, macOS and watchOS apps. We choose it when the product's audience is on iPhone and the experience must be flawless.
WHY WE CHOOSE THIS
Cross-platform tools save money at the start but lag behind new iOS features. Swift gives direct access to every Apple API on the day it ships, with no waiting for third-party libraries.
The app works with device hardware
The product uses the camera, Face ID, Apple Pay, HealthKit or background location.
Experience is a competitive edge
Smooth animations and Apple guideline compliance directly affect ratings and retention.
Branded customer apps
SwiftUI for the interface, push notifications and integration with the backend and CRM.
Apps with payments and subscriptions
StoreKit for in-app purchases and Apple Pay for paying for goods and services.
Fitness and health
HealthKit and Apple Watch data for products that track user activity and wellbeing.
Internal team tools
iPad and iPhone apps with offline mode and sync for field staff.

Why Swift and not Flutter or React Native?+
It depends on your priorities. Cross-platform frameworks cost less when you need iOS and Android at once with a simple interface. We choose Swift when the product bets on iOS, works deeply with the device or competes on experience quality.
Will we need a separate Android version?+
Yes, if you need one. Swift only targets Apple platforms, so Android requires a separate app, for example in Kotlin. We often launch iOS first and test the hypothesis before investing in a second platform.
How long does it take to build an app?+
It depends on features and integrations. An MVP with a few key flows launches much faster than a product with payments, a user account and offline mode. We set the timeline after the prototype and plan App Store publishing as a separate step.
First we find out where your customers are, and only then choose the platform.
iOS app development in Swift at GVSPACE starts with audience analysis: if revenue comes from iPhone users, a native app gives speed, stability and access to Apple Pay, Face ID and HealthKit without workarounds. We build branded customer apps, subscription products, fitness services and internal iPad tools in Swift and SwiftUI, and handle App Store publishing and further updates.
