Build error on IOS - Unable to determine Swift version

Hi, I get the following build error on IOS: 

> [!] Unable to determine Swift version for the following pods:

    - `get_version` does not specify a Swift version and none of the targets (`Runner`) integrating it have the `SWIFT_VERSION` attribute set. Please contact the author or set the `SWIFT_VERSION` attribute in at least one of the targets that integrate this pod.

Please help!
