Sorting the [Any] array

Question

Given an array defined as follow

let list: [Any]

I want to sort it WHEN

1. all the values inside it have the sa

Answer 1

For the moment, I wrote a little extension to check if all the elements are of the same type (I will be working on this to check if can get a result):

extension _ArrayType where Generator.Element == Any{

    func hasEqualTypeAndComparable()->Bool{

        if self.count > 0{
            let firstType = self.first?.dynamicType

            for val in self{
                if firstType != val.dynamicType{
                    return false
                }
            }

            return self.first is Comparable
        }

        return false
    }

}

Example:

//Example 1 
var values:[Any] = [2,1,4,3,"Hola"]
values.hasEqualTypeAndComparable() // Print false

//Example 2
var values:[Any] = [2,1,4,3]
values.hasEqualTypeAndComparable() // Prints true
