How can I simulate my app on the watch without using the iPhone?

I want to run my app on the watch without having to connect to plug in the iPhone into the computer. The reason I want to do this is because my app requires the watch to connect to a wifi network (as it needs to connect to a server), but I don't know how to make the watch connect to wifi when it is using the iPhone's bluetooth instead. The app I am creating is for watchOS 6 and is a standalone watch app. Note: the app currently works on the simulator but not when I run it on the real watch
