Swift: creating initializer generates this error: " 'super' members cannot be referenced in a root class"

I'm implementing a helper class for example:

class Helper {

    var myStr: String?

    init?(myStr:String) {
        super.init()
        self.myStr = myStr
    }
}

On this line super.init() I'm getting this error "'super' members cannot be referenced in a root class".

Any of you knows why I'm getting this error? or if there is a way for create the init without this error?

I'll really appreciate your help.

This is because this class has no superclass. It does not inherit from anything, and as such is a root class. A call to super.init() is for calling the initialiser of the superclass to ensure that inherited functionality is available as expected, but it has no relevance here.

Declaring a subclass that inherits from another class (a superclass) would look like this:

class Subclass: Superclass {
    // Code etc...
}
