iOS App Development Services from Global One Digital ship native Swift and SwiftUI applications for B2B and consumer brands across the USA, EU and CIS. Clean architecture, App Store submission, TestFlight beta workflows and ongoing maintenance — all delivered by senior iOS engineers familiar with the latest Apple guidelines and shipping practices.
Native means Swift (not Objective-C legacy), SwiftUI as the primary UI framework with UIKit interop where SwiftUI gaps remain, proper architecture (MVVM or TCA depending on team preference), Combine or Swift Concurrency for async work, and design that respects the latest Human Interface Guidelines. The application feels native to iOS rather than like a port from another platform.
Standard scope covers product discovery and feature scoping, custom UX and UI design (Apple HIG-aligned), implementation by senior Swift engineers, REST or GraphQL backend integration, push notifications via APNs, deep linking and Universal Links, in-app purchases or subscriptions, analytics with your tooling, crash monitoring (Sentry, Bugsnag), automated tests where they pay back, App Store submission with proper screenshots and review responses, and TestFlight beta distribution.
Swift with SwiftUI for new projects. Swift Concurrency (async/await, Tasks) for async work. Composable Architecture (TCA) or MVVM depending on team. Swift Package Manager for dependencies, Combine where needed. Networking via URLSession or Alamofire. Local persistence via Core Data or SwiftData. CI on GitHub Actions, Bitrise or Xcode Cloud. Distribution via TestFlight for beta testing.
An MVP iOS app ships in six to eight weeks. A production app with more screens, integrations and offline support takes ten to fourteen weeks. Apps requiring custom hardware integration (Camera, AR, Health, HomeKit, Watch companion) or significant local data work require sixteen weeks or more.
Apple ships major iOS releases yearly with deprecations and behavioural changes. Apps that skip a release start to feel dated and may fail App Store review on the next submission. Optional retainers cover iOS version support, crash monitoring, performance tuning and feature additions — usually one to four thousand dollars per month depending on app complexity.
For most B2B and SaaS apps, React Native or Flutter ships faster and costs less while feeling indistinguishable from native to users. For consumer apps with heavy graphics, ARKit or hardware integration, native Swift/Kotlin is the right call.
MVP single-platform: 6-8 weeks. Production cross-platform: 10-14 weeks. Native iOS + Android with custom modules: 16+ weeks.
Yes. We submit on your developer accounts, handle review feedback, set up TestFlight and Play Console internal testing tracks, and configure release pipelines.
Maintenance retainers cover OS update support (iOS/Android), crash monitoring, performance tuning and security patches. Typically $1.2-4K/month depending on app complexity.
Yes. We work with REST and GraphQL APIs, handle authentication (JWT, OAuth), and design caching and offline-sync strategies that match your backend constraints.
