첫째, Core, Library, Application Layer를 명확하게 구분해야 한다.
Objective-C를 고려해야 하면서 Core를 독립적으로 개발하는 것이 예전보다 더 까다로워 지고 있다. 제품의 질이 다소 떨어지더라도 하나의 플랫폼에서만 사용될 수 있는 개발 패턴은 지양하도록 하자.

둘째, 자료구조는 Core 안에 포함시켜야 한다.
가장 기본적인 String, Date, Time과 같은 Data Type은 자체 구현해주어야 한다. 각 Data Type은 플랫폼 내의 Data Type과 서로 Convert 될 수 있도록 Adaptor가 필요하다. Data Type 이외에 Linked List, Stack과 같은 자료구조도 내장하도록 하자. License에 자유로운 Open Source를 이용하는 것도 좋다.

셋째, 플랫폼에 의존적인 함수는 peer 함수로 구현하게끔 한다.
대표적인 peer 함수는 File IO, Network API, Font API 등이다. 각 플랫폼별로 implement 하게끔 구조를 만들어야 한다. 해당하는 함수들은 모두 Abstract Layer로 선언되어야 한다.
