Consumer iPhone apps
Sign-in, subscriptions, notifications and Apple Pay, built in Swift and SwiftUI.
iOS app development
iOS app development. Native Swift, App Store ready.
iPhone and iPad apps written in Swift, built to Apple’s review guidelines and taken through App Store submission to release.
Choosing iOS
A good fit when
- Your audience is mostly on iPhone, or your first market is one where iOS leads.
- The app depends on Apple features: Apple Pay, HealthKit, widgets or Apple Watch.
- Polish and performance are the product, and you want the platform’s own interface toolkit.
Think again when
- You need Android from day one as well and the budget is fixed. One shared codebase costs less. See Flutter
- The app sells digital goods on a thin margin. Apple takes a commission on those, so check the store rules first.
01 / What we build
What we build with iOS.
iPad apps for staff
Larger-screen tools for front desks, clinics and shop floors, including kiosk use.
Apple platform extras
Widgets, Apple Watch companions and Sign in with Apple, where they earn their place.
Existing app work
Objective-C to Swift migration, crash fixing and updates for each new iOS release.
02 / How it connects
What it connects to, and what to plan for.
Typical integrations
- REST and GraphQL APIs
- Apple Pay
- Sign in with Apple
- Push notifications (APNs)
- HealthKit
- MapKit
Often scoped alongside
Plan for these
App Review
Apple reviews every release against its guidelines. A rejection on a first submission is common, so the plan includes time to respond.
Apple accounts
You need an Apple Developer account in your company’s name. We build under it, so the app is yours from the first day.
Yearly iOS release
Apple ships a major iOS version each autumn. Budget a short test and fix cycle around it.
03 / Proof
iOS work you can check.

iOS questions, answered plainly.
How does a iOS project with NSDBytes run, from idea to launch?
We agree what the first release must do, design to Apple’s interface guidelines, then build in Swift in increments you can try through TestFlight. Launch covers the App Store listing, privacy details and App Review. Handover includes the code and accounts, and bugs are fixed free for 30 days.
When is iOS the right choice, and when is it not?
Native Swift is our choice when the app depends on Apple features or the audience is mostly on iPhone. If Android is needed too on one budget, a shared codebase such as Flutter usually costs less, and we say so.
Who owns the code when NSDBytes builds with iOS?
You own the code, designs and documentation made for you once the final invoice is paid. The app is built and published under your own Apple Developer account, so the listing, certificates and customer relationship are yours from the first day.
How should an early-stage iOS project be scoped and priced?
A small fixed first release, then decide. We agree the few journeys that prove the idea and price those; first releases start from $5,000. Once real users have the app, the next step is clearer. For ongoing change, a dedicated developer starts from $4,000 a month.
How does a product built with iOS grow from a first release to heavy use?
For an iOS app, growth means a codebase that can take new features and a back end that can take more users. We keep interface, logic and data layers separate, cover the important logic with tests, and design the API so it can change without forcing an app update.
