According to Apple's official documentation titled "Previewing localizations"
https://developer.apple.com/documentation/xcode/previewing-localizations/#
"For Interface Builder, you can preview localizations any time during development by choosing localizations including pseudolanguages in the preview. You don’t need to build and run your app to see the preview."
However, this functionality seems to have been removed in Xcode 15. "Preview" is not available in the Editor option menu in Interface Builder.

Xcode Version 15.0 beta 4 (15A5195m) or Version 14.3.1 (14E300c)
same issue when running iOS Simulator iPhone 14 Pro (iOS 17 or iOS 16.4) or iPhone 12 (iOS 17.0 build 21A5277j)
just started to play around with SFSpeechRecognition. Ran into the issue with SFSpeechURLRecognitionRequest.
the simple project is just a ContentView with 2 buttons ( one for selecting audio file, one for starting transcribing ), a SpeechRecognizer ( from Apple sample code "Transcribing speech to text" with minor additions )
After selecting an audio file, tap the transcribe button, the following error logs appear in the debugger console after the execution of recognitionTask(with:resultHandler:).

Since the AVURLAsset is not created manually, how to get around the initial error "AVURLAssetHTTPHeaderFieldsKey must be a dictionary"?
