I'm making a multiplayer game app using swift and I want to run the simulator in two different iPhones. I saw some other people access hardware > device and select iPhones, but in my simulator, I don't see the tab for hardware. So how can I run two phones simultaneously??
You need to use File>Open Device to open a new Simulator in the Xcode 11 Simulator app.
You can only run an app from Xcode on 1 simulator at a time. However, you can install the app on 2 different simulators, then you can manually launch it on one of the 2 (or both).
