Overview

Validates a Specification.

Extends the Linter from the Core to add additional which require the LocalPod and the Installer.

In detail it checks that the file patterns defined by the user match actually do match at least a file and that the Pod builds, by installing it without integration and building the project with xcodebuild.

  • The project uses Swift at all
  • The user did not supply a Swift version via a parameter
  • There is no swift_versions attribute set within the specification
  • There is no .swift-version file present either.
