building for iOS Simulator-x86_64 but attempting to link with file built for iOS Simulator-arm64

* 환경

2019 16인치 Intel Mac

* 오류 증상 

예전 프로젝트를 오픈하려고 했더니 다음과 같은 오류가 발생하였다.

아마도 시뮬레이터가 x86_64인데 ARM64용으로 빌드가 되어 문제가 되고 있는것으로 보인다.

이번에 M1이 나오면서 설정이 안맞는 것으로 예상이 되었다.

* 해결 방법

EGovComModule.xcodeproj > TARGETS > Build Settings > VALID_ARCHS
"arm64 arm7s arm7" 부분을 삭제 한다.

자료를 찾아보면 "x86_64"를 추가하라고 하는데 삭제 하는게 더 편하네요~ 참고 하시구요

찾아보면 몇가지 조치 방법이 있었는데

개인적으로 이렇게 하니 해결이 되었다.
