更新 Xcode 后显示错误的外部库 (pod)

Question

I've updated Xcode to the latest and all these errors came. Then I downgraded my Xcode, but the errors still there.

Answer 1

1. Open Pods project
2. Select Target of the pod with errors
3. Open Build Settings tab
4. Search for Swift Language Version ( SWIFT_VERSION )
5. Set proper Swift version for the pod
6. Build your project again
7. If build fails you set wrong Swift version, so repeat from 5
8. If some other pod will generate errors of this kind repeat from 2

Also, you may set some Swift version for Pods project itself, to set some default version.
