Description:
After upgrading to 2033 build two new error popped which before were non-existent.
The subclass of generic Enumerator type will complain with Cannot subclass sealed/static class while Enumerator<T> is nor sealed non static. Also nextObject() override will complain that I am overriding the final method, while nextObject() is not final.
public class FlatGridBreadthFirstEnumerator<T: PlainGridBreadthFirstEnumeratable>: Enumerator<T> {
....
public override func nextObject() -> T? {
let entityToReturn: T? = (_nonLazySequenceIteretorIndex < _nonLazyTileSequence.count) ? _nonLazyTileSequence[_nonLazySequenceIteretorIndex] : nil
_nonLazySequenceIteretorIndex += 1
return entityToReturn
}
}
