Can some one help me to update this package for swift 5.4

Everything looks good except the Package.swift portion.

You need to prepend a swift tools version specification to the package manifest (Package.swift), something like // swift-tools-version:3.1 ("3.1" because that's what the package intended to judging by one of its latest commit messages, but a rough scan suggests that you should be able to specify "5.5")

(also note that no whitespace is allowed between ":" and the version number prior to Swift 5.4)
