How Claude Code runs 12 iOS simulators at once
A developer squeezed 12 Claude Code agents onto a single M1 Pro MacBook, each one running its own iOS simulator in parallel. The real trick was stripping out unnecessary background services so the simulators did not choke the machine.
It turns out the bottleneck is not the agents but the simulator overhead, which means parallel coding at this scale is more about OS cleanup than raw model power.
