Answer 1

尽管 FirebaseAnyalytics 像一个单独的 pod 一样驻留，但主分支声明您必须使用 Xcode 10.3 或更高版本https://cocoapods.org/pods/Firebase

Answer 2

1. Open your podfile and comment out every single pod.

2. Run pod install so you now have zero dependencies.

3. Uncomment every pod.

4. Run pod install so you have all pods installed.

5. Build again.
