KeyError at field_list.append()

[freemant2000]

I am trying to use pyobjus to access the view with the following code:

    logging.debug("getting UIApplication")
    app_cls=autoclass("UIApplication")
    logging.debug("getting shared UIApplication obj")
    app=app_cls.sharedApplication()
    logging.debug("getting key window")
    win=app.keyWindow
    logging.debug("getting root view controller")
    ctrl=win.rootViewController()
    logging.debug("getting the view")
    vw=ctrl.view()
    logging.debug("getting the safe area insets")
    logging.debug(dir(vw))  # problem 1
    insets=vw.safeAreaInsets() # problem 2

However, it isn't working. dir(vw) returns a long blank string and calling safeAreaInsets() triggers an exception:

Same error here

The UIKit which defines this struct "uiedgeinsets" returned by safeAreaInsets (https://developer.apple.com/documentation/uikit/uiedgeinsets) is not in pyobjus "INCLUDE", so I assume it's already loaded as part of Foundation, and this code should work.
