Method has return type Any SC-T1002

Type check

Although Scala allows methods with return type Any, it is suggested that you opt for a different and a better approach. This is because dealing with Any may require calls to isInstanceOf[T] and asInstanceOf[T] and if the type argument T is erased during compilation, any calls to asInstanceOf[T] and isInstanceOf[T] will return unreliable results.

List("a", "b", "c").isInstanceOf[List[Int]]   // true
1.isInstanceOf[String]                        // false

The reason statement 1 evaluates to true is due to Scala's type erasure. So if your method returns entities whose type can be potentially lost during compilation, any good portion of the code relying on explicit casting and type checking becomes unreliable, thus affecting the overall behavior of your program.
