Optimize app performance, battery consumption, and memory management using Instruments profiling. UI/UX & Animations: Implement custom UI components, animations, and transitions while adhering to Apple’s Human Interface Guidelines. Ensure smooth user experience with optimized layouts, animations, and interactions. Location Services & Offline Capabilities: Implement Geolocation services, including background location tracking. Develop offline caching and data synchronization strategies for seamless user experiences. API Integration & Security: Work with RESTful APIs, GraphQL, and WebSockets. Implement OAuth, JWT authentication, and secure data storage following security best practices. Testing & CI/CD Automation: Write unit tests, UI tests, and integration tests using XCTest, TDD/BDD methodologies. Set up and maintain CI/CD pipelines (Fastlane, Bitrise, GitHub Actions, or Jenkins). Additional Responsibilities Mentorship & Code Reviews: Provide technical guidance and mentor junior developers. Conduct code reviews and ensure adherence to best coding practices. App Deployment & Maintenance: Handle App Store submission & review process to ensure smooth deployment. Monitor app performance using analytics, crash monitoring (Firebase, Sentry, etc.). Collaboration with Cross-Functional Teams: Work closely with backend engineers, designers, and product managers to deliver seamless features. Participate in Agile/Scrum sprint planning, backlog grooming, and retrospectives. Required Skills & Qualifications Must-Have Skills Expertise in Swift (7+ years of experience). Experience with scalable app architectures (MVVM, MVVM -C, VIPER, Clean Architecture). Strong knowledge of concurrency (GCD, Operations, async/await) and reactive programming (Combine). Proficiency in integrating and handling GeoLocation services, including background tracking. Hands-on experience with profiling, debugging, and performance tuning using Instruments. Deep understanding of Apple’s Human Interface Guidelines and best practices for UI/UX. Experience developing content-rich applications with complex animations and custom UI components. Proven track record of shipping successful iOS apps to the App Store. Strong knowledge of unit testing, UI testing, TDD/BDD, and XCTest framework. Ability to instrument mobile code for performance metrics, analytics, and crash reporting (Firebase, Sentry). Experience handling RESTful APIs, offline caching, and data synchronization. Knowledge of CI/CD pipelines for iOS apps (Fastlane, Bitrise, Jenkins, GitHub Actions). Familiarity with Dependency Injection frameworks. Experience with modularizing large iOS applications for maintainability. Good-to-Have Skills Experience with SwiftData & Core Data. Knowledge of advanced security techniques (data encryption, secure storage, biometrics). Familiarity with accessibility standards and UI testing for accessibility. Experience with GraphQL API integration. Background in ARKit, CoreML, or other advanced Apple frameworks.
