Create CMSampleBuffer from UIImage

UIImageToCMSampleBuffer

import ImageIO

    var pixelBuffer: CVPixelBuffer? = nil
    let options: [NSObject: Any] = [
        kCVPixelBufferCGImageCompatibilityKey: false,

I got this error using your code, and I used CGImage instead of UIImage

CGBitmapContextCreate: unsupported parameter combination:
 	8 bits/component; integer;
 	24 bits/pixel;
	RGB color space model; kCGImageAlphaNone;
	kCGImageByteOrder32Little byte order;
	3008 bytes/row.
Valid parameters for RGB color space model are:
	16  bits per pixel,		 5  bits per component,		 kCGImageAlphaNoneSkipFirst
	32  bits per pixel,		 8  bits per component,		 kCGImageAlphaNoneSkipFirst
