Java client for xcuitest

I have difficulty to understand how to work with the new driver…
I succeeded to run the XCUITEST driver on IOS 10 with this line…

WebDrier driver = new RemoteWebDriver(new URL(""), capabilities);

When I worked with appium before the driver was created like that :

AppiumDriver iosDriver = new IOSDriver(new URL(""), capabilities);

Few Q:

Is it the way to work with IOS 10, via selenium jars?
the appium java-client jars for appium are deprecated for IOS 10? and if not, what is the version of the java-client jar that contains the appium driver for xcuitest?

Can any one give me a direction to all the new xcuitest driver documentation (specification of the methods)?
How to find element? like in selenium, or there are new elements objects to specify in the code?
