PM-40043

📔 Objective

Exclude .build and .claude folders from Swift lint as it can cause problems when working with worktrees inside the .claude folder.
Particularly, if one has a corktree in the .claude folder and wants to compile from the main repo (not the worktree) then Swift lint will try to make it pass inside the .claude folder's worktree causing a lot of errors to appear. So in order for this not to happen we can just exclude such folders.

🤖 Bitwarden Claude Code Review

Overall Assessment: APPROVE

Reviewed the single change to .swiftlint.yml, which adds .build and .claude to the excluded list. The change is scoped, uses valid SwiftLint syntax consistent with existing entries (build, vendor/bundle), and correctly addresses the described problem of worktrees inside .claude causing spurious lint errors when compiling from the main repo. No security, correctness, or breaking-change concerns.

Code Review Details

No findings. The configuration change is correct and well-scoped.
