다른 댓글 보니까 요청할때 불필요한

code_verifier: code_challenge: 를 빼라고 하시는데 이것을 어디서 빼는지 전혀 이해를 못하겠습니다.
요청할때 파라미터 넘겨주는게 없는데 어디 사이트가서 제외 신청을 하는건지
xcode 에서는 단순한게 UserApi.shared.loginWithKakaoTalk() 코드만 실행시키는데
저 2개 파라미터는 어디에 있는건지 모르겠습니다 알려주세요

cocoapods는 사용하지 않고 있고, 3rd-Party용 swift package에 kakao-ios-sdk dependency를 추가하여 사용하고 있습니다.

카카오 로그인 코드는 다음과 같이 작성했고

if UserApi.isKakaoTalkLoginAvailable() {
    UserApi.shared.loginWithKakaoTalk(completion: { [weak self] oauthToken, error in
        guard let self else { return }

        // get kakao profile data...
    })
}

카카오 로그인 시도 시 로그는 다음과 같습니다.

로그에서는 loginWithKakaoTalk, loginWithKakaoAccount 가 동시에 사용되는 것 처럼 표시되는데요
loginWithKakaoAccount 사용하고 계시다면 디버깅을 통해 동시에 호출되는지 확인 부탁드립니다.

답변 감사합니다. 정확히 말씀해주신 문제가 있었네요.
