summary
Shows how to stop rebuilding and use Xcode’s LLDB to edit and inject code at runtime: LLDB expressions to print or assign values, fred jump to skip or rewind execution, and ignore-breakpoints to let injected methods hit inner breakpoints. Claims around 50% less rebuild time from personal tracking. Demoed changing a UIButton by casting its memory address, calling a CoreAnimation flash flush to redraw, and mentions tools like Reveal and Facebook Chisel for more stable UI and memory inspection.
