Reverse-Engineering Driven Development

Talkat iOS Conf SG 2021 · 2021-01-20..01-21· [swift]

Reverse engineering reveals concrete answers: disassemble macOS/iOS frameworks with Hopper disassembly + control-flow graph, attach with LLDB/Xcode debugging or extract caches with dsc extractor, and inspect registers and conventions. A real bug hinges on a 0.25 second event window (0.25 seconds event window) where a mouse-up within 250 ms routes to target/action instead of the framework popup; the implemented fix manually shows the popup and resolves the failure. Use a VM for unsafe work and consider debugserver on jailbroken devices.
