iOS Error Undefined symbol Testing.Trait

사용 언어: Swift 5
사용 버전: Xcode Version 16.4 (16F6)

iOS 오류 Undefined symbol Testing.Trait를 알아보겠습니다.

Xcode를 최신 버전으로 업데이트해서인지, OS를 최신 버전으로 업데이트해서 인지, 잘 되던 빌드가 갑자기 안되었습니다.

오류 내용은 다음과 같습니다.

Testing을 찾을 수 없다니, 너무 황당했어요.

많은 시행착오 끝에 알아낸 해결법입니다.

프로젝트를 눌러주시고 TARGETS에서 프로젝트를 선택 후, Build Phases로 갑니다.

거기에 Link Binary With Libraries 영역이 있습니다.

'+'를 누른 후, 아까 없다는 라이브러리 이름 'testing'을 검색해서 Add 해 줍니다.

그다음 이것을 Required가 아닌 Optional로 변경해 줍니다.

왜냐하면 이 라이브러리는 테스트할 때만 필요하니까요.

그럼 빌드를 다시 해봅시다.

굿.

끝.
