I am porting an Android native game to Unity Free, so it could be released also for other platforms like iOS. The game uses the touch screen as user input interface. I rather like to test my code to be sure this will work before purchasing Android and/or iOS Unity extensions, so:
Is there any manner of simulating drag and touch events within Unity free?
Unity has the Touch class for iOs (maybe, but I would imagine so for Android as well), also, mouse commands work too. There are also plenty of Assets which you can purchase, that help in touch manipulation.
So does Unity Free support touch yes. Can you simulate with out using a device? Yes.
Well, finally I bought iOS and Android licenses, so I can check it directly on my device. Anyway some mouse events seems to be mapped into touch ones, and for the needs of the game I am porting these are enough.
