swift - How to use multiple subclasses for function parameter

Question

Say I have 2 subclasses of a class but would like to pass either of those subclasses to a function and determine its type within the function how would that be done?

class ParentClass {
  ...
}

class subClass1: ParentClass {
 ...
}

class subClass2: ParentClass {
 ...
}

function getClassType(type: ParentClass) {
   return(type)
}

viewDidLoad...
getClassType(type: subClass2())

阿里尔打败了我，但因为我不能将帖子标记为重复，但我会发布答案。

检查对象是否为 op 类型的方法是使用is关键字：

if type is subClass1 {
    // Do stuff
}
