Answer 1

In the first place, you should compare tables using === (references), not ==.

This is one of the cases when an assertion failure is a good way to tell the compiler that no other way of the function exists e.g.:

if tableView === table1 {
    return ...
} else if tableView === table2 {
    return ...
} else {
    fatalError("Invalid table")
}

You can also use a switch:

switch tableView {
   case table1:
       return ...
   case table2:
       return ...
   default:
       fatalError("Invalid table")
}
