London, United Kingdom
$18 per hour
5 jobs
$200+ total earnings

๐Ÿš€ I've shipped real iOS & macOS apps โ€” HealthKit integrations, AI-powered tools, and App Store-ready products built with Swift, SwiftUI, and Objective-C. If you need a Senior iOS & macOS Developer who has already solved the problems your project will face, keep reading. What I've Built Over the past few years, I've developed and shipped iOS & macOS apps across health & fitness, AI tools, and on-demand services โ€” using Apple Xcode, iOS SDK, SwiftUI, and native Swift: A health insights app with Apple HealthKit, wearable data, and AI (Klarity) An AI Logo Maker with real-time design generation and dynamic templates A Thumbnail Maker with Firebase, AWS S3, and OpenAI API integration A walking & fitness app with step tracking and goal-based programs A car rental platform with booking workflows and secure authentication These weren't side projects. They were production apps built for real users and shipped through the App Store. What I Build For You โœ… Full iOS & macOS app development โ€” Swift, SwiftUI, UIKit, Objective-C โœ… iOS SDK, HealthKit, Firebase, REST API, and OpenAI integration โœ… Apple Xcode-based clean architecture built to scale, not just to ship โœ… App Store submission, approval support, and TestFlight setup โœ… Bug fixing, legacy Objective-C migration, and performance optimization How I Work I start by understanding your goal, not just your feature list. Then I build with clean architecture using SwiftUI or UIKit โ€” whichever fits your product best โ€” test thoroughly, and stay with you through App Store launch. You won't need to chase me for updates. I communicate clearly, flag problems early, and treat deadlines seriously. Who I Work Best With Founders and small teams who have a real product idea and need a Senior iOS & macOS Developer who can own the Apple ecosystem end-to-end โ€” iPhone, iPad, and Mac โ€” without hand-holding. ๐Ÿ“ฉ Send me a message with what you're building. I'll tell you honestly if I can help, which stack fits best, and how long it will take.
