iOS App Development

Overview

LNOKS builds native iOS applications in Swift using SwiftUI and UIKit where each makes sense, supporting current iOS versions back to a defined floor agreed during scoping rather than perpetual backwards compatibility. Each project covers architecture, App Store submission against Apple's App Review Guidelines, accessibility against VoiceOver and Dynamic Type, in-app purchase or subscription integration via StoreKit, and crash reporting via Crashlytics or Sentry. Founded in 2022, LNOKS has shipped 40+ products with a 5.0 Clutch rating and 96% of clients returning. iOS engagements pair with backend API development so the apps are not coupled to a single backend that becomes expensive to swap later.

Frequently Asked Questions

Frequently asked questions

Yes, we support future iOS updates. We build maintainable codebases that stay compatible with new iOS versions and evolving requirements, supporting current iOS releases back to a version floor agreed during scoping rather than chasing perpetual backwards compatibility. Crash reporting via Crashlytics or Sentry tells us quickly if an OS update introduces regressions, so fixes ship before they affect most of your users.

Yes. We follow Apple's Human Interface Guidelines to ensure high usability, performance, and smooth App Store approvals, and every submission is prepared against Apple's App Review Guidelines. Accessibility is part of that standard: we test against VoiceOver and Dynamic Type. Building to Apple's rules from the start keeps review cycles short and makes the app behave the way iOS users expect.

Yes, we help with TestFlight and beta testing. We set up TestFlight, manage beta releases, and iterate based on user feedback before the public App Store launch. Beta builds go through the same submission preparation as production releases, and crash reporting via Crashlytics or Sentry runs during the beta, so issues surface from real devices rather than only in our test environment.

We primarily use Swift and modern iOS frameworks — SwiftUI and UIKit where each makes sense — to ensure performance, security, and long-term support. Projects use StoreKit for in-app purchase or subscription integration and Crashlytics or Sentry for crash reporting. iOS work pairs with our backend API development, so the app is not coupled to a single backend that becomes expensive to swap later.
