    [!] CocoaPods could not find compatible versions for pod "Firebase/Firestore":
      In snapshot (Podfile.lock):
        Firebase/Firestore (= 10.17.0)

      In Podfile:
        cloud_firestore (from `.symlinks/plugins/cloud_firestore/ios`) was resolved to 4.13.2, which depends on
          Firebase/Firestore (= 10.18.0)

    Specs satisfying the `Firebase/Firestore (= 10.17.0), Firebase/Firestore (= 10.18.0)` dependency were found, but they required a higher minimum deployment target.

오류를 살펴보니 CocoaPods가 Firebase/Firestore의 버전 충돌 문제로 인해 종속성을 해결하지 못하고 있음을 나타냅니다.

Firebase/Firestore의 두 가지 다른 버전(10.17.0 및 10.18.0)을 맞추어보자.
