Bug Description

I have followed the installation instructions from the github readMe, and when I run swiftlint form the terminal, it correctly outputs the field with linting warnings/errors in them. However, when I add the build script to the Build Phase as 'SwiftLint'm using the bash code found in the ReadME, I consistently get this error:

Linting Swift files in current working directory
Error: No lintable files found at paths: ''
Command PhaseScriptExecution failed with a nonzero exit code

Mention the command or other SwiftLint integration method that caused the issue. Include stack traces or command output.

Environment

• SwiftLint version (run swiftlint version to be sure)
• 0.57.0
• Xcode version (run xcodebuild -version to be sure)
• Xcode 16.1
• Build version 16B40
• Installation method used (Homebrew, CocoaPods, building from source, etc)
• I used HomeBrew to install swiftlint
• Configuration file:

I do not have a yml file set-up for configurations since I am just installing swiftlint for the first time.```

Are you using [nested configurations](https://github.com/realm/SwiftLint#nested-configurations)? If so, paste their
relative paths and respective contents.
I am not using nested configurations - i am just starting a swift project for the first time and am surprised that Swift does not have a plugin like 'Prettier' for VSCode.
