Hire the Best UIkit Freelancers in Lviv, UA

iOS developer with 3+ years of experience building scalable, production-ready apps — from new MVPs to complex UIKit-to-SwiftUI migrations. I help founders and product teams ship fast while keeping codebase quality, performance, and long‑term maintainability under control. What I can do for you: • Design and build new iOS apps from scratch (Swift, SwiftUI) • Refactor and migrate legacy UIKit apps to SwiftUI safely and incrementally • Stabilize existing apps: bug fixing, crashes, performance issues, App Store rejection fixes • Implement Clean Architecture, MVVM, VIPER for testable, scalable codebases • Build AI-powered features using Core ML, OpenAI APIs, and custom ML models • Integrate Firebase, REST APIs, and third‑party SDKs (analytics, payments, auth, etc.) • Implement In‑App Purchases and Push Notifications • Handle App Store releases, CI/CD setup, and ongoing maintenance Tech stack: Swift, SwiftUI, UIKit, Combine, async/await Firebase, REST, HTTP/HTTPS, JSON iOS, macOS, watchOS, tvOS Git, GitHub, Jira, Trello Unit testing, XCTest Why clients work with me: • 100% Job Success, Top Rated Plus on Upwork • Fast onboarding, clear communication, and clean, maintainable code • Focus on long‑term architecture, not just “getting it to work” If you need an iOS developer who can quickly plug into your team, improve an existing app, or ship a new AI‑powered product, send me a message and let’s discuss your project.

30+ iOS apps live on the App Store. 10+ years building exclusively for Apple. 100% Job Success Score. Not a generalist who "also does mobile" this is all I do. Most developers spread across React Native, Flutter, Android, and whatever's trending. I made a different choice: go all-in on Apple and become genuinely world-class at it. Every project I've shipped runs on Swift and SwiftUI — no cross-platform shortcuts, no compromises on performance or native feel. The result? Apps with 4.5★+ ratings, 10,000+ downloads, and clients who come back for the next version. What my Apple-only focus means for you: — No learning curve on your budget — I know Xcode, App Store Connect, and TestFlight cold — Architecture decisions that scale — no expensive rewrites 6 months later — Zero surprise App Store rejections — I know the review guidelines inside out — Native Apple features done right: WidgetKit, Live Activities, iCloud sync, StoreKit 2, Sign in with Apple Tech I work with every day: Swift · SwiftUI · UIKit · CoreData · CloudKit · WidgetKit · StoreKit 2 · HealthKit · WatchKit · XCTest · Fastlane · TestFlight My track record on Upwork: ✔ Top Rated badge ✔ 100% Job Success Score ✔ 5+ years, 15+ apps delivered ✔ 4.5★+ average across shipped products ✔ 10,000+ combined app downloads I work best with: Founders and product teams who want a developer that cares about the product, not just closing the ticket. If native feel, App Store performance, and clean Swift code matter to you — we'll get along well. Let's talk: Tell me what you're building. I respond within a few hours and happy to jump on a quick call to see if we're a fit. Updated: 29.06.26
