Solution 1

You're probably missing a void return type.

public class Identifier {
}
public somethingMissingHere Update () {
if (Input.GetKeyDown(KeyCode.k)) {
animator.SetTrigger("sword out");
}
}

I don't know what your code is supposed to be doing or if it's supposed to be returning anything.

So, looking at what you posted, it doesn't appear as though it intends to return anything, so your answer would be void.

To add to what Dave has - correctly - said: the only time you can declare a method without a return type is when the method name is the same as the class name: when it is a constructor, and that's because the return type of a constructor can only ever be an instance of the class type.

A constructor is a special method that is never called directly - it can only be called when you instantiate a class by using the new keyword:

C#

public class MyClass
   {
   public MyClass() 
      {
      ...
      }
   }
...
MyClass x = new MyClass();

The only exception to that is when the constructor is static - then it is never called directly, but called by the system at some point prior to the first usage of the class.

If you omit the return type to a "normal" method, the system assumes you wanted to create a constructor, but then complains because it can't work out when to call it.
