Question 1

How do I install FengNiao on macOS?

Accepted Answer

Install via Mint with `brew install mint` and `mint install onevcat/fengniao`, or compile from source using Swift Package Manager as detailed in the README's installation section.

Question 2

Does FengNiao work with asset catalogs in Xcode?

Accepted Answer

Yes, it scans for .imageset files in asset catalogs by default, but it only detects assets referenced via string names in code, so dynamically loaded assets might be missed.

Question 3

FengNiao vs. Xcode's built-in asset management – which is better for cleanup?

Accepted Answer

FengNiao automates detection and deletion of unused images, while Xcode offers manual management. FengNiao is faster for large projects, but always verify results to avoid deleting needed assets.

Question 4

How to exclude CocoaPods folders from FengNiao scanning?

Accepted Answer

Use the --exclude flag, e.g., `fengniao --exclude Pods`, to skip third-party directories, as recommended in the usage examples to prevent accidental tampering with vendor resources.

Question 5

Is FengNiao safe to use in a CI/CD pipeline?

Accepted Answer

Yes, with options like --force and --xcode-warnings, it can be integrated to fail builds on unused files, but test thoroughly in a staging environment first to avoid production issues.

Question 6

Can FengNiao detect unused resources in SwiftUI projects?

Accepted Answer

It scans Swift files, so it should work, but it might not catch assets referenced via SwiftUI's Image("name") syntax if the string isn't explicitly matched; check the regex patterns for accuracy.
