Hi @AndyDee,
I followed your tips but it doesn’t work for me. I think the problem is the Simulator itself, not the script because I can run it well in real device ( iPad with ios 7, iPhone 5s with ios 8)
My currently workaround, thanks to @bootstraponline’s suggestion, is to use AppleScript to navigate to the center of the simulator window and keep pressing the mouse there while running the script and it works.
I port https://github.com/vicwomg/swipeInWindow.py to java because the original version is written in python.I know it’s not an ideal solution but it’s the only one that work for me at this moment. My environment is Xcode 6.1, Appium 1.3 and it seems like Apple did not fix this yet
