Crash with "-[GMSCoordinateBounds CGRectValue]: unrecognized selector sent to instance"

I use Google Maps for iOS and get always a crash when launching Reveal 9 from AppCode with the following error message:
-[GMSCoordinateBounds CGRectValue]: unrecognized selector sent to instance

Of course GMSCoordinateBounds has no CGRectValue method, so Reveal shouldn't call it.

Please fix that. Thanks.

    We've had a look and Google Maps for iOS doesn't crash Reveal out of the box. Reveal only reads properties defined by UIKit, and none of those return the GMSCoordinateBounds value type.

    Is your app storing to, or returning GMSCoordinateBounds from any of the following properties (or properties like them)?

    I looked everywhere and couldn't find any place where I assign GMSCoordinateBounds to anything other than temporary local variables.
    It's used for a call to "moveCamera(...)" and the result from "map.projection.visibleRegion()", which is immediately converted to something else and the GMSCoordinateBounds variable then removed from the stack.

    But my map usage is very complex.
    Please, just add a "respondsToSelector" test before you call on any objects found via reflection.

    We'll look at adding a fix in a future release, thanks for the detail.

    It's worth pointing out that Reveal reads a pre-defined list of properties from a pre-defined list of UIKit classes, so it is possible that something in your view hierarchy is returning a GMSCoordinateBounds value from a property or method that should be returning CGRect.

    It may not cause you any issues, but it's worth keeping an eye on.
