Apple’s canceled iOS multitasking UI lives on, with AI-enhanced emulation
AI-summarised brief · reviewed before publication
An AI‑assisted emulator revived an unreleased iOS 4 multitasking interface that Apple abandoned after the iPhone 4 prototype. The interface, resembling Expose, displayed open apps as on‑screen cards and allowed double‑tap Home switching. The video, posted by developer Steve Troughton‑Smith, runs build 8A218 on a QEMU fork, sourced from a prototype root filesystem. Apple’s own AI tools, such as Xcode 27 agents, underscore the growing role of AI in software preservation and development.
