[!] CocoaPods could not find compatible versions for pod "Firebase/Performance":
In Podfile:
firebase_performance (from `.symlinks/plugins/firebase_performance/ios`) was resolved to 0.7.0-2, which depends on
Firebase/Performance (= 7.11.0)
None of your spec sources contain a spec satisfying the dependency: `Firebase/Performance (= 7.11.0)`.
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* out-of-date source repos which you can update with `pod repo update` or with `pod install --repo-update`.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.
