Does not work on iOS, `SWIFT_VERSION`

[liuyuejiang]

• clipboard_manager 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.
