What is XCMonkey?
xcmonkey is a tool for doing stress testing of iOS apps. It's inspired by and has similar goals to monkey on Android.
Under the hood, xcmonkey uses iOS Development Bridge as a driver, that's why it's pretty smart and can do a lot of things, such as taps, swipes and presses. All that comes «pseudo-random» because it has access to the screen hierarchy, and so can either do actions blindly (like tapping on random points) or precisely (like tapping on the existing elements).
