How to change a parameter to accept variables in swift 3?

Question

I'm just starting to learn iOS Development and i'm watching a slightly outdated video on functions. In the video based on swift 2 the instructor did

Ex.

func example(var a: Int){


}

In swift 3, you can not do this to change the argument passed to a variable, does anyone know how I could do this in the current syntax?

You need to use var like this in swift 3.0 with function parameter.

func example(a: Int){
    var a = a
}

You can read more about this here SE-0003
