Passing notifications between different places of application

Notifications holder:

class Notifications{
    let testNotification    = SimpleNotification<String>         (name: "Example.testNotification")
}

Notifications handler:

class SampleClass {
        //instance of notifications holder
        var notifications = Notifications()
        init(){
            //subscribe
            notifications.testNotification.subscribe{ value in
                print("value: \(value)")
        }
    }
}

Notifications caller:

class AnotherClass {
    func post(){
        //post
        Notifications().testNotification.post("comunicationBetweenDifferentClassesExample Test text")
        //or use
        //SimpleNotification<String>(name: "Example.testNotification").post("comunicationBetweenDifferentClassesExample Test text")
        //but it is not safe
    }
}

Example:

let
sampleClass = SampleClass(),
anotherClass = AnotherClass()
anotherClass.post()
//comunicationBetweenDifferentClassesExample Test text will be printed
