Native language
Swift and iOS development
Swift is the language Apple built for its own platforms. An app written in it gets the full range of iPhone and iPad features, and the look and feel that Apple users expect. We build native iOS apps where that depth matters, and say when a cross-platform tool is enough.

At a glance
What it is
Swift is Apple's programming language for building native apps for iPhone, iPad, Apple Watch, and Mac, with full access to each device's features.
Problems it solves
Some apps need the best possible fit with Apple's devices, deep use of their features, or early access to new ones, which cross-platform tools cannot always give.
Who it suits
Businesses whose customers are mostly on iPhone, and teams building apps that rely on Apple-specific features.
How to choose
Choose native Swift for apps that depend on deep device features or an Apple-first audience. Choose cross-platform when reaching both platforms matters more.
What it means
Apple's own language for its own platforms
Swift is a programming language created by Apple for building apps on its devices. Apps are usually built with SwiftUI, Apple's framework for describing screens, together with Apple's other frameworks for cameras, location, payments, and health data.
Working in Apple's own tools means new platform features are available as soon as Apple releases them, and the app follows Apple's design conventions without extra effort.
The cost is that an iPhone app is only an iPhone app. An Android version is a separate build, in a different language, unless you chose a cross-platform tool at the start.
What DECHY can do
Working with Swift
Build
- Native iPhone and iPad apps in Swift and SwiftUI.
- Interfaces that follow Apple's guidelines.
Connect
- Back ends, sign-in, and push notifications.

How we work
From idea to the App Store
Shape the app
We agree who it is for, what it does first, and what can wait.
What it produces
- Scope
- Screen map
Design and prototype
We design the screens, and build a clickable prototype to test with real users.
What it produces
- Designs
- Tested prototype
Build and test
We build in short cycles, test on real devices, and distribute builds to your team.
What it produces
- Working builds
- Test results
Prepare for review
We prepare the store listing, privacy details, and the review submission.
What it produces
- Store listing
- Review submission
Launch and support
We release in stages, watch crashes and feedback, and plan updates.
What it produces
- Release
- Update plan
Where it fits
What native iOS gives you
| Area | What native iOS gives you | What to weigh |
|---|---|---|
| Look and feel | Apple's standard behavior, animations, and accessibility support. | A custom look takes more design effort. |
| Device features | Full access to the camera, sensors, health, payments, and widgets. | Each feature has review rules and privacy requirements. |
| New releases | New iOS features are available as soon as Apple ships them. | Apps need updating each year for new versions. |
| Performance | The best control over speed and battery use. | Rarely a deciding factor for ordinary business apps. |
| Reach | Excellent in markets where iPhone dominates. | No Android audience without a second build. |
Choosing the right approach
The App Store has rules
Apple reviews every app, and has rules on payments, privacy, and content. An app can be delayed or rejected for reasons unrelated to its quality, and some business models face restrictions.
We check the rules against your plans early, so review is rarely a surprise.
Common questions
Questions about Swift
Is Swift only for iPhone?
It also builds apps for iPad, Apple Watch, Apple TV, and Mac, and parts of it can be used on servers.
Should we build iPhone first and Android later?
That is a sensible path if your audience leans to iPhone. We plan the back end so both apps can share it.
What about cross-platform tools?
Flutter and React Native can reach both platforms from one codebase, at some cost in depth. We compare them for your app.
Do you handle the App Store submission?
Yes. We prepare the listing, privacy details, and the submission, and respond to review feedback.

Technical depth
How we build with Swift
For your developers and IT lead: our Swift choices on structure, data and security, and quality, and the reasoning behind each.
We build with SwiftUI, organize code by feature, keep business logic apart from views, and use Swift's concurrency features for network and storage work.
- The Keychain for credentials, and local storage with clear rules for syncing.
- Certificate checks and careful handling of permissions.
- Offline behavior designed from the start where it matters.
- Unit and interface tests in a pipeline, and testing on a range of real devices.
- Accessibility checks with VoiceOver and larger text sizes.

Describe what the app does and which devices your users have. We will say whether native iOS is justified and what an Android version would involve.
