What We Build

Elmeris delivers end-to-end iOS app development — from architecture and UI design through development, testing, and App Store launch. Every app is built native: no web wrappers, no cross-platform compromises.

iPhone & iPad Apps

Universal applications optimised for all current iPhone and iPad models and screen sizes.

SwiftUI Interfaces

Modern, declarative UI built with SwiftUI for fast development and pixel-perfect design.

Swift Backend Integration

Clean Swift networking layers connecting to REST APIs, GraphQL, Firebase, and custom backends.

Core Data & CloudKit

Offline-capable apps with local persistence and iCloud sync using Apple-native storage layers.

In-App Purchases & Subscriptions

StoreKit 2 integration for consumables, non-consumables, and auto-renewable subscriptions.

Push Notifications

APNs integration for rich notifications, background refresh, and user-targeted messaging.

How We Work

01

Discovery

We define scope, target audience, platform requirements, and technical architecture.

02

Design & Prototyping

UI/UX design following Apple Human Interface Guidelines, reviewed before development begins.

03

Development & QA

Iterative Swift development with unit and UI testing on real devices and simulators.

04

App Store Launch

Full submission support: provisioning, review guidelines compliance, metadata, and screenshots.

App Store Publishing Included

Every iOS project includes full App Store submission support. We handle provisioning profiles, certificates, App Store Connect setup, screenshot production, and guideline compliance review — so your app ships without delay.

Elmeris also publishes its own apps on the App Store, so we bring first-hand knowledge of the submission process, review patterns, and what it takes to pass review on the first attempt.
