Code To Reproduce Issue [ Good To Have ]

    ((IOSDriver)driver).activateApp("com.apple.mobilesafari");

    sleep(5);

    Set<String> contextNames = ((SupportsContextSwitching) driver).getContextHandles();//tried IOSDriver also

    System.out.println("contextNames : "+ contextNames);

    sleep(10);

    contextNames = ((SupportsContextSwitching) driver).getContextHandles();

    System.out.println("contextNames : "+ contextNames);

    sleep(10);

    contextNames = ((SupportsContextSwitching) driver).getContextHandles();

    System.out.println("contextNames : "+ contextNames);

Reproduce the issue with the provided IOSDriver code on a real iOS device using Java client 8.3.0 and Appium 2.0.0-beta.55. Start by tracing SupportsContextSwitching.getContextHandles() and compare its returned contexts with Appium Inspector; done means the web context is discoverable after activating Safari.
