Carthage build skipped on Apple Silicon

[csforbes]

running carthage update --use-xcframeworks --platform iOS with github "NYTimes/NYTPhotoViewer" in Cartfile results in this message:
*** Skipped building NYTPhotoViewer due to the error: Dependency "NYTPhotoViewer" has no shared framework schemes for any of the platforms: iOS

• xcode-select version 2397
• carthage version 0.39.0
• Apple M2
• Ventura 13.3.1

Carthage requires --use-xcframeworks for builds on Apple Silicon.

It looks like Carthage support is intended; I'd be happy to take a swing at fixing this if someone could give me a starting point.
