[!] CocoaPods could not find compatible versions for pod "Firebase/CoreOnly":
In snapshot (Podfile.lock):
Firebase/CoreOnly (= 7.3.0)
In Podfile:
Firebase/MLVisionBarcodeModel was resolved to 5.0.0, which depends on
Firebase/CoreOnly (= 5.0.0)
firebase_core (from `.symlinks/plugins/firebase_core/ios`) was resolved to 0.7.0, which depends on
Firebase/CoreOnly (= 7.3.0)
You have either:
* out-of-date source repos which you can update with `pod repo update` or with `pod install --repo-update`.
* changed the constraints of dependency `Firebase/CoreOnly` inside your development pod `firebase_core`.
You should run `pod update Firebase/CoreOnly` to apply changes you've made.
