Haven't reached out to confirm with upstream but as the website states "Swift Mailer integrates into any web app written in PHP 5, ..." I'm not exactly certain PHP 7 is a concern. I have attempted to build latest version 5.4.2 under Sid following the suggestions in the ticket and the package doesn't pass lintian checks when it uses php-cli instead of php5-cli. The build itself is using pkg-php-tools to build and it is simply a PHP class not compiled code.
