iOS Simulator: window capture records video without audio, application capture records audio but captures the full Mac screen

What happened?

I am trying to record an iOS Simulator for an app advertisement video.

When selecting the Simulator as a Window, BetterCapture records only the Simulator window, but no app/system audio is captured.

When selecting the Simulator as an Application, the app/system audio is captured correctly, but the recorded video becomes the entire display instead of only the Simulator application.

As a result, I cannot record only the Simulator window together with its audio.

Is this expected due to a ScreenCaptureKit limitation, or is it a BetterCapture-specific issue?

What did you expect to happen?

I expected BetterCapture to record only the iOS Simulator window while also capturing the Simulator application's audio.

If "Application" capture is used, I expected the recording area to match the Simulator application's visible bounds instead of the entire display.

Steps to Reproduce

1. Launch an iOS app in Xcode Simulator.
2. Open BetterCapture.
3. Select Simulator as "Window".
4. Record.
   -> Only the Simulator window is recorded, but no app audio is captured.
5. Select Simulator as "Application".
6. Record.
   -> Audio is captured correctly, but the recorded video becomes the full Mac display.

I also tried disabling:

• Show Wallpaper
• Show Window Shadows
• Show Dock
• Show Menu Bar

The behavior did not change.

Thanks for reporting this. I will take a look in the coming days. IIRC, I had a similar issue in the past and I believe it was a limitation of SCK, but I need to verify.
