Why can we use 'static' in a class of Swift language? [duplicate]

Question

Normally we should use keyword class to define a class computed property, like

class Square{
    class var area:Float{
        return 100.0*100.0
    } 
}

However we can not use class to define a stored property (I know it results from OC).

And meanwhile we may use static in a class to define a stored property and it runs successfully.

So my question is: what are the differences between static and class when used in a class?

The main difference between static and class is that class elements can be overridden.

As a short way to say this, static has the same effect that final class.

You can refer to this question to have more details.

I would refer to this, basically, you can override a class func/var, but you cannot a static one.
