LiveContainer is an iOS application that acts as a runtime host for running third-party iOS apps (guest apps) without actually installing them. It leverages extensive reverse engineering of Apple's dyld, Mach-O binary format, and private iOS APIs to bypass code signing, inject tweaks (via CydiaSubstrate/ElleKit), manage multiple data containers per app, and provide multitasking (floating dock, Picture-in-Picture). The project includes a full code signing library (ZSign), a dyld validation bypass, hooking infrastructure, and integration with AltStore/SideStore for certificate import and app refreshing. The architecture is modular with separate targets for the main app, SwiftUI UI, tweak loader, signing library, process launcher, and share extension. While the code demonstrates deep iOS internals knowledge and is actively maintained, its heavy reliance on private APIs and dyld internals makes it fragile across iOS versions and limits the reusability of most components outside this specific project.
