Introduction
Add
SwiftLint
plugin to Swift Package.Purpose
In order to see warnings and errors in Xcode when using

SwiftLint
in a Swift Package, we need to create a plugin that will run theSwiftLint
tool at build time. This PR creates a plugin that will do that by using theSwiftLint
binary. Using the binary instead of pulling in theSwiftLint
package as a dependency will reduce the build time. In the future, we could pull this out into its own package to be used in all our swift packages. This is possible today but there are issues in Xcode that prevent it from reliably showing warnings in Xcode. This is being resolved in Xcode 14 and should be out in the Fall.
