testing a new watch app in simulator with older iOS device

I have an app that runs on an older iOS test device. I want to make a watch app that takes news feeds from that app and displays it on the watch. I don't have a watch, but want to use the simulator to test it. I have a version of the iOS app that works find on the simulator, but I'd need to run both the iOS and WatchOS apps in simulators to test.


Can I run an iOS app on a simulator AND run a watch app on a simulator at the same time in order to test file transfer between them?


If not, can I update the device and have it transfer a file to the watch simulator from a test device?


I assume the file transfer between my app and the watch would be BT.
