I know that Roblox studio allows simulation of TouchScreen events such as TouchEnded. However, is there a way to test TouchSwipe without simulating it on a device? I've been trying for a while now, but no matter how much I click and move my mouse, I can't seem to trigger this test code:
game:GetService("UserInputService").TouchSwipe:connect(function()
print("Swiped!");
end)

I don't believe there is a way to do this, however you could replace the event with something else, such as a mouseclick.
Download an emulator.
You can't. If you own an iOS device then you can use studio on it. On an android device you can join the published game and look at the developer console.
Use something called MEmu, it is an android emulator for use on PC. Quite useful. It is also free.
