Kotlin has become a powerful language for creating any kind of applications, like Java, but with some special productive features. Maybe it's nice to have this in Deepsource.

Add support for Composer when debugging PHP codes. If I use PHP dependencies, DeepSource run "composer install" (result's can save to temporary vendor folder by command - maybe after scanning can delete it) before scan starting. Just created more fake issue without vendor folder detection. (I dont want store vendor files in github repo.)

Add support for Swift - https://developer.apple.com/swift/

Add support for C++.

The user should be able to re-run the full analysis on a repository manually.

It'd be great if the Test Coverage Analyzer can detect if parts of the codebase that have a high churn (are changed frequently) lack coverage. This will help teams identify critical areas that lack testing.
