Native iOS development with Swift and SwiftUI
Swift is the programming language Apple recommends for its platforms, and SwiftUI is its declarative framework for building interfaces. Together they are the right choice when an app must feel completely at home on iPhone and iPad or rely on advanced Apple features.
Native Swift apps get immediate access to every Apple framework, from HealthKit and ARKit to widgets and background tasks, and deliver the smoothest performance and most faithful platform behaviour. SwiftUI makes interfaces quicker to build than older UIKit code, while UIKit remains available where finer control is needed. The main trade-off is that Android needs a separate app. If both platforms matter equally and the app is mainly forms and data, React Native or Flutter is usually more economical.
What we build with Swift / SwiftUI
- Native iPhone and iPad apps
- Apps using camera, AR, health or Bluetooth features
- Widgets, watch and companion apps
- Performance-sensitive media apps
- Updates to existing UIKit apps
Swift / SwiftUI questions
Should we use SwiftUI or UIKit?
SwiftUI suits most new screens and is faster to build with. UIKit is still valuable for complex custom interfaces and for existing apps, and the two can be combined.
Do we need a Mac to develop iOS apps?
Building and submitting iOS apps requires Apple tooling that runs on macOS. We handle this as part of development and can publish under your Apple developer account.
How long does App Store review take for a Swift app?
Most submissions are reviewed within a few days, although rejections for guideline issues add another round. We check common rejection causes, such as missing privacy descriptions or incomplete sign-in options, before we submit.
Can a Swift app work without an internet connection?
Yes. We store data locally with SwiftData, Core Data or SQLite and sync changes with your server when the connection returns, so key screens stay usable offline.
How are push notifications handled on iOS?
Notifications are delivered through Apple Push Notification service, using keys held in your Apple developer account. We handle permission prompts, deep links from notifications and server-side sending.
Which Apple features can a native Swift app use?
Native apps get full access to features such as Face ID, Apple Pay, HealthKit, widgets, Live Activities, Siri shortcuts and Apple Watch companions, often before cross-platform tools support them.
How do you test a Swift app before release?
We write unit and UI tests with Apple's testing tools, run them on a range of simulators and real devices, and distribute pre-release builds to your team through TestFlight.
What drives the cost of a native iOS app?
The main factors are the number of screens, the complexity of the back end and integrations, offline and sync requirements, and whether you also need an Android app built separately.
Who owns the app and the App Store listing?
The app is published under your own Apple developer account and the source code sits in your repository, so you keep full control of the listing, reviews and future releases.
How do we keep a Swift app working after new iOS releases?
Apple releases a major iOS version every year, so we test against the betas, update deprecated APIs and adopt new requirements before they become mandatory for submission.
