isAutoDualCameraFusionEnabled always returns false on iPhone X & Xs Max?

Camera capture on my iPhone Xs Max, iOS 12.1, when creating the session output using AVCapturePhotoOutput() I check it's isAutoDualCameraFusionEnabled value to see if the hardware supports dual camera fusion, and it always returns false. Also tested on my iPhone X, and got same result.


This is leading me to think I'm misunderstanding how what this setting means and is used?

This is expected behavior. Dual camera fusion was supported on the iPhone 7 Plus, but did not carry forward to iPhone 8 Plus, iPhone X, iPhone XS, or iPhone XS Max.

That is strange because AVCapturePhotoSettings().isAutoDualCameraFusionEnabled is always true, on both iPhone XS Max and iPhone X.


Why does AVCapturePhotoSettings disagree with AVCapturePhotoOutput?

isAutoDualCameraFusionEnabled always returns false on iPhone X & Xs Max?
