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
