Experienced iOS Developer Needed to Ship & Scale a SwiftUI App

Remote Full-time
Seeking an experienced iOS developer to help bring a SwiftUI app to a production-ready state. The core functionality of the app is complete, and I'm looking for a skilled contractor to resolve outstanding technical issues and implement two remaining key features.

Primary Scope of Work

Performance Optimization – Diagnose and resolve current performance bottlenecks to ensure a smooth, responsive user experience

Bug Fixes – Address a handful of known bugs

Email Authentication – Implement secure email-based user authentication (via Firebase Auth)

In-App Subscriptions – Integrate StoreKit 2 to support tiered subscription plans with proper receipt validation and entitlement management

Please note that the above represents the primary deliverables.

There is additional work beyond this initial scope spanning UI/UX polish, new feature development, and backend/API work.

Requirements

Proven experience with SwiftUI and native iOS development

Familiarity with Apple's StoreKit 2 framework

Experience integrating third-party authentication providers

Strong debugging and performance profiling skills (Instruments, Xcode)

Comfortable working across the full stack — from UI polish to backend integration

Ability to work independently with clear communication
