SwiftUI #Preview generate localizable strings in the Xcode String Catalog

Since Xcode 15.1, when compiling SwiftUI previews (using #Preview macro), strings that are unique to #Preview declarations are getting extracted and processed to the application's localizable strings catalog. In Xcode 15.0.1, this still works as expected and only UI strings from non-preview UI declarations are extracted and processed. Afaik, there is no setting for this in Xcode 15.1 and up. Anyone knows any other solution to avoid our catalog gets muddled with preview strings?

I've already been reporting this via the Feedback hub since 15.1, but have had 0 responses from Apple on this.
