本文探讨了Swift语言中==与===运算符的区别。==用于比较值类型是否相等，类似于Objective-C中的isEqual:行为；而===则检查两个引用类型是否指向同一内存地址，类似于Objective-C中的指针相等性比较。
In swift 3 and above
=== (or !==)
- Checks if the values are identical (both point to the same memory address).
- Comparing reference types.
- Like
==in Obj-C (pointer equality).
== (or !=)
- Checks if the values are the same.
- Comparing value types.
- Like the default
isEqual:in Obj-C behavior.
Here I compare three instances (class is a reference type)
