For converting from MultiArray values what outputs of CoreML model to Image, CoreML Helpers are very convenient.
1, Download CoreMLHelpers files from GitHub page above.
2, Copy CoreMLHelpers files in your Xcode project.
3, Make CGImage from MultiArray values.
let cgimage = multiArray?.cgImage(min: -1, max: 1, channel: nil, axes: (3,1,2))
If MultiArray values are -1…1 , specify (min: -1, max 1). In other case, if they are 0…255 , specify (min: 0, max 255).
