Welcome to the forum.
Swift analyser is already included in the Enterprise Edition you have normally downloaded on our website.
Can you check in the content of extensions/plugins folder of your SonarQube server?
Or re-download a fresh SonarQube 7.9 or 8.1 (LTS or latest version) from https://www.sonarqube.org/downloads/ ?
As Carine said, Swift plugin should come with the initial setup of your SonarQube Enterprise Edition container. I suspect that something went wrong during the initialization of the container.
