Walkthrough

This pull request removes several YAML files that defined security rules targeting hard-coded secrets in Swift code. The removed files handled detection for HKDF, PKCS5, Scrypt, and webview configuration issues. Along with these rule definitions, associated test snapshot and test suite files have also been deleted, eliminating the corresponding validation mechanisms from the codebase.

Changes

Files	Change Summary
rules/swift/security/…-hardcoded-secret-swift.yml	Removed security rule files for HKDF, PKCS5, Scrypt, and WebView base URL misconfigurations including rule definitions, severity, messages, and constraints.
tests/__snapshots__/…-swift-snapshot.yml	Deleted snapshot files for HKDF, PKCS5, Scrypt, and WebView configuration, eliminating stored test references for these security rules.
tests/swift/…-swift-test.yml	Removed test suite files for HKDF, PKCS5, Scrypt, and WebView configurations that validated both valid and invalid scenarios of the corresponding security checks.

Poem

I’m a rabbit in the code field, hopping with glee,
Clearing out secrets that no longer need to be.
Hard-coded strings vanish in a flash,
Leaving our codebase fresh in a dash.
With tests and rules removed so neat,
I celebrate with a joyful beat —
Hoppy code days, oh what a treat!
🐇🎉

🪧 Tips

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
