Can I convert .png data into an Int in Swift?

Question

I convert an image into .png data from a UIImageView and print result on console with this code:

    let img = img_view.image!.pngData()
    print(img)

The result of this snippet is 232206 Bytes Can I get only 232206 as integer output, without the "bytes" suffix?

Answer 1

That's the size (number of bytes) of the Data , which you can access by .count :

let sizeOfData = img.count // 232206

After all, Data represents a collection of bytes, so it conforms to Collection , which has the count property.

Answer 2

Use count property:

let imgData = imgView.image!.pngData()
    let imgBytesCount = imgData!.count
    print(imgBytesCount)
