wdVisible Predicate returns invalid type

Issues/Bugs
1

Using this predicate string
wdVisible == 1

i.e.
collectionView.findElementsByIosNsPredicate(“wdVisible == 1”);

returns an error for wdVisible
[<XCElementSnapshot 0x608000565100> valueForUndefinedKey:]: this class is not key value coding-compliant for the key wdVisible

i believe it should be isWDVisible==1 but isWDVisible is not supported.
