What you get with this Offer
I will build one complete feature for your iOS application — from data model through business logic to SwiftUI or UIKit UI — following MVVM architecture, with unit tests for the ViewModel and integration tests for the data layer, delivered as clean, documented Swift code ready to merge into your main branch. Feature development that cuts across the full stack of an iOS application (model, networking, persistence, business logic, and UI) requires architectural consistency and discipline that isolated contractor work often lacks when each layer is built without coordinated design.
The feature build covers data model definition, networking or Core Data integration for data access, ViewModel with published state for SwiftUI or delegate callbacks for UIKit, UI implementation matching your design specification, input validation, error state handling, loading state, empty state, and accessibility support. Unit tests cover ViewModel state transitions and business logic; UI tests cover the primary user flow through the feature. All code follows Swift API design guidelines and your existing project conventions.
This service suits iOS development teams who need a specific feature built to production quality — user profile editing, push notification management, in-app purchases, onboarding flow, settings screen, activity history, or any defined feature scope — without diverting internal resource from current sprint priorities.
