Display Zoom causes sizeInches to be nil (with iPhone 12 mini)

[kevinrenskers]

When running on an iPhone 12 mini

UIDevice.current.dc.screenSize.height = 812 UIDevice.current.dc.screenSize.scale = 3 UIDevice.current.dc.screenSize.sizeInches = 5.8

But with Display Zoom turned on I get these values:

UIDevice.current.dc.screenSize.height = 693 UIDevice.current.dc.screenSize.scale = 3

And since there is no match, sizeInches is nil.
