Xcode 12: No AVCaptureDevice.Format.supportedColorSpaces property - Simulator compile only

Since updating to Xcode 12, I have had a build time error, but only when compiling for the Simulator. (arm7 & arm64 compilations have no errors and the app runs without runtime errors.)

These build errors are all related to AVCaptureDevice.Format from AVFoundation. The error says that AVCaptureDevice.Format doesn't have a property/member named 'supportedColorSpaces'. Below are the errors in some context. I'm at a loss for why I would see this during simulator compiles only. The property clearly exists in the latest documentation. and has for a long time.

Can anyone give me a clue what the cause might be?

Code Block 
let format: AVCaptureDevice.Format = ...
...
// Error: Value of type 'AVCaptureDevice.Format' has no member 'supportedColorSpaces'
if format.supportedColorSpaces.contains(AVCaptureColorSpace.P3_D65) {
    videoDevice.activeColorSpace = AVCaptureColorSpace.P3_D65
}

Code Block 
let device videoDeviceInput: AVCaptureDeviceInput = ...
...
// Error: Value of type 'AVCaptureDevice.Format' has no member 'supportedColorSpaces'
if videoDeviceInput.device.activeFormat.supportedColorSpaces.contains(AVCaptureColorSpace.P3_D65) {
    ...
}
