I've been building software since 2011, specializing in iOS development. I've worked extensively with Objective-C, Swift, and React Native, and have dabbled in web development with Node, React, and Next.js. I enjoy projects to improve DX and love building and optimizing custom CI/CD pipelines.
Based in Fort Myers, Florida, and I enjoy travel, finance, and all things technology. Oh, and I chronically install day-one iOS betas on my personal devices!
When two windows share iPhone Duo's inner display, neither one is told which side it's on. I built a proof of concept in Xcode 27.1 and found the fold's ReservedRegion answers it, once you know its frame is clipped to your window.
When iPhone Duo is open, its outer display faces the same way as the rear camera. CameraCaptureAccessory lets your app put content there while it records. Here's how to build a scrolling teleprompter with it in SwiftUI and UIKit.
iOS 27.1 lets you read iPhone Duo's hinge angle and fold status with onHingeChange in SwiftUI and UIHingeInteraction in UIKit. Here's how the APIs work, why they're for interactive effects rather than layout, and a fold-to-scrub example.
iPhone Duo reserves parts of its displays for the fold and the front cameras. Learn which regions exist, when system views handle them for you, and how to query ReservedRegion in SwiftUI and UIKit to move custom content out of the way.
