Thanks for the issue @freedom-isnotanarchy! I'll go through our issues and see if we have individual issues already filed for these 3 requests. Also did you mean to include more detailed links in the description that shows the support? Would you mind if I removed the excessive duplicated support.tidelift.com links from the issue?

excessive duplicated support.tidelift.com links

Feel free, to remove.
I'm just including, to show Parity with Grype. As well as any Gap that Grype has with TideLift. (It was a copy/paste)

Happy to take on adding support in Syft and Grype for Swift/CocoaPods once I finish up Hex support

Hello all, I believe that all three of the requested platforms are supported in some fashion here, on the Syft side:

Cocoapods: anchore/syft#1081
Gradle/Kotlin: anchore/syft#1719
Rust/Cargo: anchore/syft#345

I'll go ahead and close this issue. If I am misunderstanding the requests here, or if we are missing any functionality for the above, please open a new issue with specific details. Thank you!
