We can convert CMSampleBuffer to NSData with following function.
But we could not find a way to convert it to Data.

We tried using

   Data(bytes: <#T##UnsafeRawPointer#>, count: <#T##Int#>)

instead of

   NSData(bytes: <#T##UnsafeRawPointer?#>, length: <#T##Int#>)

but no luck.
Is there anyone who could do it.

func frameData() -> NSData {



        let imageBuffer = CMSampleBufferGetImageBuffer(sampleBuffer)



        CVPixelBufferLockBaseAddress(imageBuffer!, CVPixelBufferLockFlags(rawValue: 0))



        let bytesPerRow = CVPixelBufferGetBytesPerRow(imageBuffer!)

        let height = CVPixelBufferGetHeight(imageBuffer!)

        let src_buff = CVPixelBufferGetBaseAddress(imageBuffer!)

        let nsdata = NSData(bytes: src_buff, length: bytesPerRow * height)



        CVPixelBufferUnlockBaseAddress(imageBuffer!, CVPixelBufferLockFlags(rawValue: 0))





        return nsdata



    }

Just used

       let data = Data(bytes: src_buff!, count: bytesPerRow * height)

instead of

     let nsdata = NSData(bytes: src_buff, length: bytesPerRow * height)  

The key is here was ! after src_buff for Data.
Because xCode was showing some errors which is not related ! usage I could not understand ! was needed.
