AI Helps Revive a 15-Year-Old Shelved Project: Apple's iOS 4-Era Card-Based Multitasking Interface Revealed

AI summary

IT之家, Nov 13: AppleInsider reported that a never-released iPhone multitasking interface, dormant for over 15 years, has been brought back to life using AI and emulator technology; the outlet had reported in early 2010 that Apple was testing an Exposé-like window overview, and in 2011 a special iOS 4 build carrying the interface was found on an iPhone 4 prototype.

The video shows the Exposé-style multitasking UI Apple tried during iOS 4 development, with open apps laid out as cards in a 3x3 grid so users could double-click the Home button and pick an app directly without scrolling.
