Hello guys, I constantly keep getting error code -12780 while saving the file.Configuration isAVAssetWriterInput(mediaType: AVMediaType.video, outputSettings: [ AVVideoCodecKey: AVVideoCodecType.h264, AVVideoWidthKey: floor(UIScreen.main.bounds.width / 16) * 16, AVVideoHeightKey: floor(UIScreen.main.bounds.height / 16) * 16, AVVideoCompressionPropertiesKey: [ AVVideoAverageBitRateKey: 2300000, ], ])I don't understand what NSOSStatusErrorDomain -12780 means. The localized description is The operation could not be completed.Other than that I discovered that on my iOS 13 beta device the error code is: -17508,but still is The operation could not be completed.

Hello, I've been using macOS Mojave in night mode for a while now and I noticed that some website loads in dark mode when in reality their not. So I looked into the documentation but I didn't find any informations about the dark mode website support. Do you know something about how to support dark mode on websites and maybe how to detect if safari is in dark mode?Thank you very much,Marco.
