Hey! Tell me how to make a transformation using this framework convert WGS84 height (wkid: 4326, verticalWkid: 115700) to DHHN2016 (wkid 4258, verticalWkid: 7837)

Similar to this answer, but with simple features.

    SFPGeometryTransform *transform = [SFPGeometryTransform transformFromEpsg:4326 andToEpsg:4258];
    
    SFPoint *point = [[SFPoint alloc] initWithXValue:13.403729270903389 andYValue:52.51064626078732];
    SFPoint *transformedPoint = [transform transformPoint:point];
    
    SFPoint *point3d = [[SFPoint alloc] initWithXValue:13.403729270903389 andYValue:52.51064626078732 andZValue:100.0];
    SFPoint *transformedPoint3d = [transform transformPoint:point3d];
