swift设计模式-原型模式

    原型模式的本质,就是方便对一个对象继承的同时多态化处理

    /*:
    🃏 Prototype
    ------------
    
    The prototype pattern is used to instantiate a new object by copying all of the properties of an existing object, creating an independent clone. 
    This practise is particularly useful when the construction of a new object is inefficient.
    
    ### Example
    */
    class ChungasRevengeDisplay {
        var name: String?
        let font: String
    
        init(font: String) {
            self.font = font
        }
    
        func clone() -> ChungasRevengeDisplay {
            return ChungasRevengeDisplay(font:self.font)
        }
    }
    /*:
    ### Usage
    */
    let Prototype = ChungasRevengeDisplay(font:"GotanProject")
    
    let Philippe = Prototype.clone()
    Philippe.name = "Philippe"
    
    let Christoph = Prototype.clone()
    Christoph.name = "Christoph"
    
    let Eduardo = Prototype.clone()
    Eduardo.name = "Eduardo"
