Platform capability

We build native iOS apps in Swift.

Swift and SwiftUI, built for how iOS actually feels, tested on real devices, and submitted to the App Store. From a focused utility to a companion for your web product.

Talk about an iOS build

Can Foundri build a native iOS app?

Yes. We build native iOS apps in Swift, using SwiftUI for modern interfaces, and we ship them to the App Store. We handle the whole path: product and interface design, the build, testing on real devices, App Store Connect setup, review guidelines, and submission. You get a clean codebase you own. When a project needs to reach Android too, we tell you honestly whether native or cross-platform is the better call.

We have native iOS apps in the App Store and more in build. Swift and SwiftUI are mature and well documented, and this is a stack we ship on regularly.

Two ways to build, and how we pick

Most iOS decisions come down to one question: is this iOS-first, or does it need Android on day one? We settle that before we write code.

Native iOS

Swift

A true native app in Swift. Best performance, best feel, full access to the platform.

Language
Swift, with SwiftUI for the interface
How it ships
Built in Xcode, tested on real devices, submitted through App Store Connect.

What it gives you

  • SwiftUI interfaces that feel native
  • Full device access (camera, notifications, HealthKit, location)
  • Offline storage and sync
  • In-app purchases and subscriptions
  • Widgets, live activities, and app extensions

What you can do with it

  • Consumer apps people keep open
  • Companions to a web product
  • Focused single-purpose utilities
  • Anything that needs to feel truly native

Pick this when

iOS is the priority and the experience has to feel first-class. If you are targeting iPhone users first, this is it.

Cross-platform

iOS + Android

One codebase that ships to both stores, when reaching both fast matters more than squeezing out platform-only features.

Language
React Native or Flutter, chosen to fit
How it ships
Built and submitted to both the App Store and Play Store.

What it gives you

  • One codebase for iPhone and Android
  • Native modules where you need them
  • Shared logic with your web app when it makes sense

What you can do with it

  • B2B and internal apps
  • Content and utility apps
  • Getting to both stores on one budget

Pick this when

You need iOS and Android at once and the app is not leaning on deep, platform-only features.

Devices we build for

iOS-first, designed for the range of screens your users actually carry.

iPhone
The primary target. Built and tuned for current iPhones and recent models still in wide use.
iPad
Universal apps that adapt to the larger screen, when your product benefits from it.
Apple Watch
Companion experiences and glanceable features, where they fit the product.
Widgets and extensions
Home screen widgets, share extensions, and live activities that live outside the main app.

What we build on iOS

  • Consumer apps built to be opened daily
  • Companion apps for an existing web product
  • Focused, single-purpose utilities
  • Apps using camera, notifications, HealthKit, and location
  • Subscriptions and in-app purchases
  • Prototypes to prove an idea before the full build

Our approach

We build iOS apps that feel like they belong on the platform, because that is what makes people keep them. SwiftUI for interfaces that match how iOS moves, real-device testing rather than simulator-only, and a clean submission through App Store Connect so review is not a surprise. When Android matters too, we say so early and pick the path that fits, rather than defaulting to native and quietly doubling the budget.

How an iOS build runs

  1. 1

    Shape and scope

    We cut the idea to the core experience and agree on scope, platforms, and timeline.

  2. 2

    Design for iOS

    Interface design that respects the platform's patterns, not a web layout forced onto a phone.

  3. 3

    Build and test on device

    Weekly progress, tested on real hardware, so it feels right in the hand and not just in the simulator.

  4. 4

    Submit to the App Store

    App Store Connect setup, review guidelines, assets, and the submission itself. We handle it.

  5. 5

    Release and improve

    Ship, watch real usage, and run ongoing release cycles if you want us to.

What to know before you build

iOS is a great platform to ship on, with a few realities worth naming up front.

App Review is a gate
Apple reviews every app and every update. We build to the guidelines and handle submission, but review can add days, and some ideas need rethinking to pass. We flag those early.
Native means iOS-only
A native Swift app does not run on Android. If you need both, we plan for it from the start, either cross-platform or two native builds, and we are honest about the cost of each.
You need an Apple Developer account
Shipping to the App Store requires a paid Apple Developer account in your name. You own it, we operate in it.
Some things only prove out on hardware
Camera, sensors, and performance need real devices. We test on hardware rather than trusting the simulator for anything that touches them.

Native iOS questions, answered

Do you build native or cross-platform?
Both, and we pick based on your product. Native Swift when iOS quality is the priority, cross-platform when you need iOS and Android from one budget. We tell you which fits before we start.
Do you handle App Store submission?
Yes, end to end. App Store Connect setup, review guidelines, assets, and the submission itself.
Can you add to an app we already have?
Often yes. We review the existing code first and tell you honestly what we find.
Will we own the code and the App Store listing?
Completely. The code is yours, and the app ships under your own Apple Developer account.
How long does an iOS build take?
A focused app often reaches the App Store in 6 to 10 weeks. Larger apps run longer. We agree on scope up front so there are no surprises.
What about Android?
If Android matters, we usually build cross-platform so both ship from one codebase, or two native apps when the product demands it. We make that call with you, not for you.
