如何将图像数据传递给Swift MagicWand？

Question

read（）API接受数据类型但是如何读取数据？ https://github.com/naithar/MagickWand/blob/master/Sources/MagickWand/Wand/ImageWand/ImageWand%2BRead.swift#L51

let urlImage:URL? = URL(fileURLWithPath: "files/test.png")

        do {
            let inputImage = try Data(contentsOf: urlImage!)
            dump(inputImage)  //image is exist
            let wm = ImageWand(data: inputImage)

            //wm?.read(data: inputImage)
dump(wm?.imageBytes)  //return Optional([])
dump(wm?.data) //return nil
            dump(wm?.size.width)  //return 0
            dump(wm?.size.height)  //return 0
        } catch {
            print(error)
        }
