iOS App Development
Swift apps built to App Store guidelines the first time, for an audience that notices when something feels wrong.
iOS users are unforgiving about interaction detail in a way that shows up directly in reviews. They also sit behind the strictest app review process in the industry, where a guideline breach costs you a release cycle. Both are manageable — if they shape the build rather than being discovered at submission.
Who this is for
Products whose audience skews iPhone, which in most consumer and premium B2B segments it does. Companies where in-app purchase or subscription revenue matters. Teams that have been rejected by App Review and want the next submission to pass.
Problems we solve
- App Review rejection. Guideline breaches — sign-in options, purchase routing, privacy strings — found after submission.
- Interactions that feel wrong. Non-standard gestures and transitions that iOS users immediately notice.
- Privacy requirements. Nutrition labels, tracking permission and purpose strings handled as an afterthought.
- Subscription complexity. StoreKit, receipt validation, restore, upgrade and refund paths done incompletely.
- Deprecation churn. APIs removed at the next major release with no migration planned.
What we build
- Swift apps using SwiftUI, or UIKit where the requirements call for it
- StoreKit 2 in-app purchases and subscriptions with server-side receipt validation
- Sign in with Apple, Face ID and Touch ID, and Keychain-backed credential storage
- Push notifications, universal links, widgets and App Clips where they earn their place
- Offline storage with Core Data or SwiftData and background refresh
- App Store submission, privacy declarations, TestFlight and phased release
How we work
We build to the Human Interface Guidelines because iOS users read deviation as a defect. App Review requirements are addressed during development — privacy strings, permission rationale and purchase routing are structural, not paperwork. TestFlight goes to real users before the store does, and releases go out phased.
Technologies we use
Swift, SwiftUI and UIKit, Combine and async/await, Core Data and SwiftData, StoreKit 2, and Xcode Cloud or GitHub Actions for builds, with Laravel or Node.js backends.
Business benefits
- Submissions that pass review rather than costing a release cycle
- Subscription revenue handled correctly, including the edge cases
- An app that feels native, which is what protects your rating
- TestFlight feedback from real users before public release
Common questions
How long does App Review take?
Usually a short turnaround now, but a rejection restarts it — which is why we treat guideline compliance as a build requirement rather than a submission checklist.
Do we have to use Apple's payment system?
For digital goods and subscriptions consumed in the app, generally yes, and the commission should be in your pricing model from the start. Physical goods and services are different. The rules shift with regulation and we will advise on the current position for your case.
SwiftUI or UIKit?
SwiftUI for most new work — faster to build and maintain. UIKit where you need fine-grained control or must support older iOS versions. Mixing both is normal and often correct.
