처음보는 엄청난 에러창에 조금 놀랐지만, 해당 에러는 Xcode13 버그인걸로 보인다.
이를 해결하는 방법은 간단하다. 두가지 방법이 있는데…

첫번째 해결방법

터미널 콘솔에 아래 코드를 입력해준다.

sudo xcode-select -s /Application/Xcode-beta.app/Contents/Developer

두번째 해결방법

위 사진처럼 Project Document의 Project Format을 변경해준다.

  • Xcode 12.0-Compatible로 변경해주면 됩니다.

위 두 방법 중 하나를 선택해 pod init을 진행하면 해결완료!
