How to define options for CIFIlter?

When creating a raw image with CIFilter, I need to provide and identifier hint for the raw image decoder. How do I do this? The following code does not populate the dictionary and CIFilter returns nil. How would I do this correctly? I am completely stuck. let rfo = [ String(kCGImageSourceTypeIdentifierHint) : "com.sony.raw-image" ] as! [CIRAWFilterOption:Any] let cii = CIFilter(imageData: data , options: rfo).outputImage

How to convert raw pixel data to raw image for CIFilter?

I have raw pixel data from a camera sensor and need to convert it into a raw image. With Core Image Filter I like to process the raw image data. I have trouble getting the raw data into a CIImage. Also CGContext only gave me gray scale or even black & white image views. The raw data are the actual pixel values of the CFA (color filter array) with an RGGB pixel arrangement. iOS/SWIFT should be able to do all the demosaicing and apply a whole bunch of great filters specially developed for raw images. But I simple cannot get the data into a core image. Any help is highly appreciated.

CareKit ViewControllers and SwiftUI?

I like the simple and easy plotting functionality of CareKit. How can I use CareKitUI‘s OCKCartesianChartView with SwiftUI? OCKCartesianChartView seems not to be compatible with View and VStack of SwiftUI ?! Any hints and help are highly appreciated.
