喵神在“Designated，Convenience和Required”小节部分，PDF的44页最后说到：“所有的convenience初始化方法都必须调用同一个类中的designated初始化完成设置，另外convenience的初始化方法是不能被子类重写或者从子类中以super的方式被调用的。”，而在该小节最后说到：“对于convenience的初始化方法，我们也可以加上required以确保子类对其进行实现”，在这两部分，前一个说convenience方法不能被子类重写，后面又说可以被重写，不知是不是鄙人才疏学浅，不知大意，所以还请喵神指教。

我也遇到了这个问题，看了《The Swift Programing Language》（中文版）中构造过程这一章节，我觉得Convenience的初始化方法是可以被子类重写的
