How do I take a screenshot on Apple TV?

With the Apple TV connected to your development machine via USB:

Steps

1. Launch Xcode from the menu select Window → Devices

2. Select the Apple TV on the left representing your device.

3. On the device, configure the screen the way you want to capture it.

4. Click on the Take Screenshot button.

5. It will save the screenshot on Desktop.

I would just snap a picture of the TV screen with a smartphone (or any other) camera and use this for the bug report.
