Overview
What iOS developers do, and why native still matters
An iOS developer builds apps for Apple's platforms: iPhone, iPad, Apple Watch and sometimes Mac and Apple TV. Native iOS apps are written in Swift, Apple's own language, using Xcode and Apple's frameworks. The user interface is usually built with SwiftUI today, while many older apps still use UIKit. A good iOS developer knows both, because most real projects mix them.
Native matters when your app leans on the device. HealthKit data, Apple Pay, home screen widgets, Live Activities on the lock screen, Siri and Shortcuts, background location and Apple Watch complications all work best, or only work, in native code. Cross-platform tools can reach many of these features, but they add a layer between your app and the platform, and new Apple features arrive in Swift first.
Apple also runs a strict gate. Every build goes through App Store review, and every update follows the App Store Review Guidelines. Rules on in-app purchases, privacy labels, account deletion and data collection can reject a release just before launch day. An experienced iOS developer designs around these rules from the first sprint, so review becomes a routine step and not a nasty surprise.
When you hire iOS developers from Dware, you get engineers who have shipped and maintained real App Store apps. They plan the architecture, write tested Swift code, set up TestFlight for your team, handle submission and keep the app current when Apple ships a new iOS version each autumn. You get daily or weekly updates and senior code review on every change.
What we build
iOS app development services
Our iOS developers cover the full Apple platform, from a first iPhone MVP to watch apps, subscriptions and accessibility work on a mature product.
Native iPhone and iPad apps
We build new apps in Swift and SwiftUI with layouts that adapt from small iPhones to large iPads. iPad apps get proper split view, keyboard shortcuts and pointer support, not a stretched phone screen.
Apple Watch apps and complications
We build standalone and companion watchOS apps with SwiftUI, plus complications and Smart Stack widgets. Workout, health and quick-action apps are a natural fit for the watch.
In-app purchases and subscriptions with StoreKit
We implement StoreKit 2 for subscriptions, one-time purchases and free trials, with server-side receipt checks through the App Store Server API. Paywalls follow Apple's rules so they pass review.
HealthKit and fitness apps
We read and write health data with HealthKit, ask for only the permissions you need and explain them clearly to users. Apple reviews health apps closely, so we build privacy in from the start.
Push notifications, widgets and Live Activities
We set up Apple Push Notification service with rich and time-sensitive notifications. We add home screen and lock screen widgets with WidgetKit and Live Activities for deliveries, rides or sports scores.
UIKit maintenance and SwiftUI migration
We take over existing UIKit and Objective-C apps, fix crashes and move screens to SwiftUI step by step. Old and new code run side by side, so you never stop shipping.
App Store rejection fixes
We read the rejection, find the guideline behind it and fix the app or reply to the reviewer in App Store Connect. Common causes are payment rules, missing account deletion and unclear permission text.
Accessibility audits and fixes
We test with VoiceOver, Dynamic Type, Voice Control and high contrast, then fix labels, focus order and touch targets. Accessible apps reach more users and are easier to test automatically.
Our process
How our iOS developers build your app, step by step
Every iOS project follows the same clear path. Each step has Apple-specific work in it, and you see a running build on your own iPhone early.
- 1
Discovery and App Store fit
We start with a free call about your users, your goals and the devices you need. We check your idea against the App Store Review Guidelines early, for example whether digital content must use in-app purchase and whether you need Sign in with Apple. We decide which iOS versions to support, usually the current one and the one before. You get a written scope and a fixed quote.
What you get
- Feature list and scope
- Review-risk checklist
- Minimum iOS version
- Fixed quote
- 2
UX that follows Apple's design
We map screens and flows using Apple's Human Interface Guidelines and native patterns such as tab bars, sheets and navigation stacks. We plan for Dynamic Type, dark mode and the current iOS design language from day one. Permission prompts get clear wording, because vague text is a common rejection reason. Your designer can work in Figma and we turn it into SwiftUI.
What you get
- Screen map and user flows
- Permission prompt copy
- Design review notes
- 3
Architecture and project setup
We set up an Xcode project with Swift Package Manager modules so features stay separate and testable. Most apps use SwiftUI with an observable model layer and Swift concurrency with async and await. We pick storage, such as SwiftData, Core Data or a simple file cache, and design the networking layer and offline behaviour. Signing, bundle IDs and capabilities are set up in your own Apple Developer account.
What you get
- Xcode project in your repo
- Architecture document
- Signing and capabilities set up
- 4
Build in short sprints with TestFlight
We build in one- or two-week sprints and ship each one to TestFlight. Your team installs the build on real iPhones and sends feedback straight from the app. Internal testers get builds right away, while external testers need a short beta review by Apple. Every pull request gets senior code review before it merges.
What you get
- TestFlight build every sprint
- Sprint demo
- Reviewed pull requests
- 5
Testing on real devices
We write unit tests with Swift Testing or XCTest and UI tests with XCUITest for the key flows like sign-up and checkout. We test on real devices, including an older iPhone and an iPad, and on the oldest iOS version you support. We check memory and battery use in Instruments and run VoiceOver through every screen. Crash reporting is live before the first external tester sees the app.
What you get
- Automated test suite
- Device test matrix
- Accessibility pass
- 6
App Store submission and release
We prepare the App Store listing: screenshots for each device size, the privacy nutrition label, the app privacy manifest and the review notes with a demo account. We submit through App Store Connect and handle any questions from the reviewer. You can launch with phased release, which rolls the update out over seven days so problems show up early. The app goes live under your own developer account.
What you get
- App Store listing assets
- Privacy label and manifest
- Approved release
- 7
Support and yearly iOS updates
After launch we watch crash reports and App Store reviews and ship fixes fast. Each June Apple previews the next iOS, and each September it ships. We test your app on the betas over the summer, so it works on release day and can use new features. Apple also raises the minimum Xcode and SDK versions for uploads, and we keep your project ready for that.
What you get
- Crash and review monitoring
- iOS beta testing
- Update releases

Inside our iOS development work
This is the detail that separates an app that ships once from one that lasts for years on the App Store.
SwiftUI and UIKit side by side
SwiftUI is our default for new screens because it is faster to build and easier to keep consistent. Some things still work better in UIKit, such as complex text editors, custom camera views or very large lists with special behaviour. We bridge the two with UIViewRepresentable and UIHostingController, so each screen uses the right tool. This also lets older apps move to SwiftUI one screen at a time.
Swift concurrency and data safety
Modern Swift uses async and await, actors and strict concurrency checks to catch data races at compile time. We write networking, syncing and database code with these tools, so the app stays responsive and does not crash at random. We migrate older callback code with care. Swift 6's stricter checks find real bugs, and we fix them instead of switching them off.
Privacy rules Apple enforces
Apple asks every app for a privacy nutrition label, and apps and SDKs must declare the reasons they use certain system APIs in a privacy manifest. If you track users across other apps, App Tracking Transparency requires a permission prompt. Apps that let users create accounts must let them delete their account inside the app. We audit third-party SDKs too, because their data collection counts as yours.
Payments that pass review
Apple requires in-app purchase for digital goods and subscriptions used inside the app, while physical goods and real-world services use Apple Pay or a normal payment provider. The exact rules differ by country and change over time, and we check the current guidelines for your markets. We build StoreKit 2 flows with restore purchases, family sharing and subscription offers. Your server gets App Store Server Notifications, so access stays correct when a user renews, cancels or asks for a refund.
Release automation
We set up continuous integration with Xcode Cloud, GitHub Actions or Bitrise. Every merge runs the tests, and builds go to TestFlight automatically with fastlane or Xcode Cloud workflows. Signing certificates and profiles are managed in one place, so a new laptop or a new developer does not break the build. Releases become a button press instead of a half day of manual steps.

FAQ
Hire iOS developers: frequently asked questions
Why hire native iOS developers instead of using React Native or Flutter?
Cross-platform tools are a good choice when you need iOS and Android quickly with one codebase. Native iOS is better when the app relies on Apple features such as HealthKit, widgets, Live Activities, Apple Watch or advanced camera and Bluetooth work, or when you want the smoothest possible feel. New Apple features also arrive in Swift first. We build both ways, so we will recommend the option that fits your product, not the one we prefer.
How much does it cost to hire an iOS developer?
Cost depends on the scope and the number of screens, which Apple features you need, backend and integration work, whether you also want iPad or Apple Watch support, your timeline and the size of the team. A focused MVP costs much less than a full app with subscriptions, health data and a watch app. After a short call we give you a free, fixed quote, so you know the full cost before any work starts.
How long does it take to build an iOS app?
A focused MVP usually takes 8 to 14 weeks from kickoff to the App Store. You see the first TestFlight build in 1 to 2 weeks and a new one every sprint after that. Larger apps with subscriptions, offline sync or an Apple Watch app take longer. App Store review itself usually takes one to three days, and we plan a buffer for any reviewer questions before your launch date.
Will my app pass App Store review?
We cannot control Apple's decisions, but we greatly reduce the risk. We check the design against the App Store Review Guidelines during discovery, follow the in-app purchase and privacy rules, add in-app account deletion where needed and give the reviewer a working demo account. If a reviewer does reject a build, we read the guideline they cite, fix the issue or reply in App Store Connect, and resubmit quickly.
Do you still work with UIKit and Objective-C?
Yes. Many successful apps still have large UIKit or Objective-C codebases, and rewriting them all at once is rarely wise. We fix bugs and add features in the existing code, then move screens to SwiftUI gradually where it makes sense. SwiftUI and UIKit can live in the same app, so you keep shipping updates while the codebase gets more modern behind the scenes.
Can you build an Apple Watch app or widgets for my existing app?
Yes. We add watchOS apps, complications, home screen and lock screen widgets, Live Activities and App Intents to existing iPhone apps. These share code and data with your main app through app groups and shared Swift packages. They are a good way to keep users engaged without opening the app, for example showing a delivery status on the lock screen or logging a workout from the wrist.
How do you handle in-app purchases and subscriptions?
We use StoreKit 2 for products, subscriptions, free trials and offer codes, and we test every flow in the StoreKit testing environment and the sandbox before release. Your backend receives App Store Server Notifications, so access updates when users renew, cancel or get a refund. We also add restore purchases and follow Apple's rules on paywall wording, because unclear subscription terms are a frequent cause of rejection.
How do you make iOS apps accessible?
We support VoiceOver, Dynamic Type, Voice Control, Reduce Motion and high contrast on every screen. SwiftUI gives a good base, but custom controls, images and charts still need clear labels and a sensible focus order. We test by hand with VoiceOver on a real iPhone and with Xcode's Accessibility Inspector. Accessible apps also tend to be easier to automate in UI tests, which helps quality overall.
Who owns the app, the code and the Apple Developer account?
You do. We publish the app under your own Apple Developer Program account, either as an individual or an organization, and add our developers as team members with only the roles they need. The code lives in your repository from the first commit. You own all code and IP, and we sign an NDA on request before you share any details.
Do you support the app after launch?
Yes. We offer post-launch support that covers crash monitoring, bug fixes, App Store review replies and small features. Each summer we test your app on the new iOS betas, so it works on the September release day. We also keep the project up to date with Apple's minimum Xcode and SDK requirements, which change yearly and block new uploads if you fall behind.
