[!] CocoaPods could not find compatible versions for pod "Firebase/Storage":

[!] CocoaPods could not find compatible versions for pod "Firebase/Storage":
  In Podfile:
    firebase_storage (from `.symlinks/plugins/firebase_storage/ios`) was resolved to 10.2.11, which depends on
      Firebase/Storage (= 8.14.0)

None of your spec sources contain a spec satisfying the dependency: `Firebase/Storage (= 8.14.0)`.

You have either:
 * out-of-date source repos which you can update with `pod repo update` or with `pod install --repo-update`.
 * mistyped the name or version.
 * not added the source repo that hosts the Podspec to your Podfile.

해결법 (Apple-Silicon인 경우)

$ cd ios
$ rm Podfile.lock
$ rm -rf Pods
$ arch -x86_64 pod install --repo-update
