Thank you for your detailed reply. We’ve downloaded and installed Xcode 16 Beta 4. Here are our findings: The Preview string is no longer being extracted in our sample project. We are still seeing strings from previews when we export our real app, but we need to investigate further before jumping to conclusions. Yes, we can happily confirm that the IDE Export Localizations command is now working for our real app. Understood that build schemes won’t apply to exports. Thank you for clarifying. Thank you for confirming that the -configuration option is not yet supported. We have filed Feedback # FB14595554 per your request. We’ll follow up on the preview strings shortly.

Following up on the remaining preview strings that are still being exported. We’ve confirmed that they are all declared in Text( ) expressions that exist in helper views defined outside the preview view. So there is no reasonable way for Xcode to recognize them as preview-only. In short, Beta 4 is looking very good. Thank you!
