Required. ARC is just a compiler technology that automatically inserts retain/release by scanning the code. C++ code is not within the scope of recognition by the compiler, and the life cycle can only be managed by itself.
In addition, ARC technology is a "backward" technology that has to be used because the Obj-C language itself cannot implement automatic reference counting. For C++, you can directly use the smart pointer classes provided by the standard library such as shared_ptr/unique_ptr/weak_ptr. Able to write code as clean as ARC. In a sense, using smart pointers, C++ objects do not need to be released manually.
