Answer 1

For XCode 10.1, select your Pods File

-> Go to Build Settings -> Choose your Pod -> Search "Swift" -> Navigate to "Swift Language version" -> Set to desired language version.

Answer 2

You have code which was compiled on the new Xcode 10.2 or the beta version which supports Swift 5. Update your Xcode to the latest version.
