Review-ready
Built to pass App Store review.
Apple rejects apps for thin content, unclear permissions and missing account deletion. These requirements are designed in from the start, which avoids a late scramble. Approval itself is decided by Apple.
iOS app development company · India
iOS app development company, held to the App Store standard.
CodingMarble is an iOS app development company in India, building iPhone and iPad applications for businesses whose customers expect the polish, privacy and reliability they associate with the Apple platform.
Apps are written in Swift and SwiftUI, or in Flutter and React Native when an Android version is planned, and they are prepared for App Store review from the first screen, not at the end.
Native feel
An app that behaves like an iPhone app.
Navigation, gestures, haptics, Dynamic Type and dark mode follow the Apple Human Interface Guidelines, so the app feels familiar the first time someone opens it.
Privacy
Permission prompts with a reason.
Location, camera and tracking requests appear only when needed, in plain wording. Sign in with Apple is included wherever other social logins are offered, as Apple requires.
iPhone application development
Swift and SwiftUI, or a shared codebase.
For iPhone application development that relies on the camera, HealthKit, widgets, Apple Pay or fluid animation, native Swift is the dependable choice. SwiftUI app development shortens interface work considerably and is used for new screens, with UIKit where a mature component is still the better tool.
If your audience is split between platforms, Flutter or React Native can deliver iOS and Android from one codebase at lower cost. The trade-off is slightly slower access to the newest Apple features on release day. The written scope states which approach is used and why.
- Native Swift and SwiftUI
- Apple Pay and widgets scoped
- Flutter or React Native option
- Approach justified in the scope
iPad and business apps
Beyond the phone: iPad, kiosks and internal apps.
Requests for iPad app development are often for tools, not consumer apps: a sales catalogue for field teams, a clinic or hotel check-in kiosk, a restaurant ordering tablet, or an inspection form that works offline in a warehouse and syncs once the connection returns later.
These apps use the larger screen properly, with split views, drag and drop, Apple Pencil signatures and external keyboard support where useful. Distribution need not be public: private release through Apple Business Manager or TestFlight can be scoped, so an internal app never appears on the open App Store.
- Field sales and catalogue apps
- Kiosk and check-in screens
- Offline forms that sync later
- Private distribution can be scoped
App Store submission
From TestFlight build to a live listing.
The iOS app development process ends with more than code. An App Store submission service covers certificates and provisioning, TestFlight builds for your own testers, screenshots for the required device sizes, the privacy nutrition label, age rating answers and the review notes Apple asks for.
If Apple raises a query, the response and any fix within scope are handled for you. Review times are set by Apple and cannot be promised. The app is published through your own Apple Developer account, so the listing, ratings and customer relationship remain entirely yours.
- Certificates and provisioning handled
- TestFlight builds for your testers
- Privacy label completed with you
- Published under your Apple account
