Mudassir A.

iOS developer (Swift, SwiftUI, UIKit) with 10+ years shipping production apps. I fix App Store rejections, rescue inherited codebases, and update apps for iOS 26/27: Liquid Glass, resizable iPad windows, and the new foldable iPhone. What I’m hired for most: 🪟 iOS 26/27 updates: Liquid Glass, iPad resizing & foldable iPhone. I migrate UIKit/SwiftUI screens to Liquid Glass (glassEffect, new tab bars and toolbars). I move apps to the scene lifecycle so they work in resizable iPad windows, Stage Manager and Split View. I also adapt layouts for the foldable iPhone’s cover and inner screens, including iOS 27 split screen and smooth fold/unfold transitions. 🔴 App Store rejections: Guideline 2.1 and 4.3, IAP/subscription issues, crash-on-launch. Diagnosed, fixed and resubmitted. Most clients are back in review within 72 hours. 🔧 Legacy codebase rescue: you inherited a project, the original dev is gone, and nothing builds. I audit it, stabilize crashes, fix the architecture, and hand you a clear roadmap. 🚀 New builds: production-ready SwiftUI/UIKit apps with Swift 6 concurrency, built to be handed off cleanly. ⚡ Hard integrations: HealthKit, BLE/CoreBluetooth, CoreML, StoreKit 2. The work most iOS devs quietly avoid. Domains I know deeply: health & fitness (HealthKit, calorie/bariatric tracking), IoT & BLE hardware sync, subscription SaaS, AI-powered apps, streaming apps.

You get written updates, not silence. 📩 Send me your App Store link or your rejection email. I’ll tell you exactly what’s wrong and what it takes to fix, before you pay me anything. I usually reply within 4 hours.
