Swift Method

1. prepare 메서드

 

2. destination

 

3. failible initializer

 

4. % 인코딩

 

5. 완성된 앱의 Main.storyboard

- Tab bar Controller Scene: 탭 바를 제어하며 해당 탭 클릭 시 해당 Scene으로 이동

- box office Scene: 박스오피스 순위 테이블

- theater Scene: 웹사이트를 통해 영화관 위치 검색

- Detail View Scene: box office Scene에서 테이블 터치 시 해당 Scene으로 이동되며, 웹사이트에서 해당 영화를 검색한 페이지가 출력됨

 

6. 생성형 AI를 통해 소스 리팩토링
