Is any iOS automation framework able to go to system settings and check some settings ex click on wireless networks ?
I really need some automated interacting . Is appium able to do that ?
Appium can't do that, SeeTest from Experitest might be able to give you access to wireless network settings.
Sikuli can automate this (in the emulator on the Mac).
SikuliX automates anything you see on the screen of your desktop computer running Windows, Mac or some Linux/Unix. It uses image recognition powered by OpenCV to identify and control GUI components. This is handy in cases when there is no easy access to a GUI's internals or the source code of the application or web page you want to act on.
I don't know about Appium, but WebDriverAgent certainly can interact with any app or the OS home screen, settings, etc. Appium does support WebDriverAgent as one of its backends, but I don't know if Appium adds some limitations or if it exposes all of WebDriverAgent's functionality.
