I only see the benefits on this.
1. We don't have to store all states in one file. States can be stored
separately. So, we can write code in more composition style.
2. We can add new states to the existing type. Not just NSObject subclass
with associated object.
protocol Incrementer{
func increase()
}
extension Incrementer{
var count = 1 //
allows stored properties
func increase(){
print(count)
count = count + 1
}
}
