iOS cluster control is a technique for centrally managing and batch-operating multiple iPhones from one computer, with no jailbreak and no signing.
This one answers: How Should iOS Cluster Control Connect? USB vs WiFi.
The difference is cable vs wireless,both can run scripts and view multiple screens.
Choose USB when
- Many devices in one rack or room
- Long sessions viewing screens and debugging
- You want the most stable wired link
Choose WiFi when
- You do not want cables everywhere
- Phone and PC are on the same WiFi
- Desks move occasionally
See the comparison in Connection guide. When unsure: connect one device over USB first, then decide if WiFi saves effort.
