swift: percentage of download

Question

I want to get percentage of download in label. I use this code:

cell.label?.text = "\( (CGFloat(totalBytesWritten) / CGFloat(totalBytesExpectedToWrite)) * 100)"

But in this case I get numbers of percentage after the point.

I tried to use different code but it not help:

cell.label?.text = "\( (Int(totalBytesWritten) / Int(totalBytesExpectedToWrite)) * 100)"

How to get percentage like this 98% and not like this 98.5353457%?

`cell.label?.text = "\(Int( (totalBytesWritten/totalBytesExpectedToWrite) * 100))"`? — Larme, Jul 17 '18 at 16:22
@Larme I get 0 when download start or 100 if download completed. Not numbers in progress. — , Jul 17 '18 at 17:31

Try Int(CGFloat(totalBytesWritten) / CGFloat(totalBytesExpectedToWrite) * 100.0)

Try this

let progress = Float(totalBytesWritten) / Float(totalBytesExpectedToWrite)
progressLabel.text = String(format: "%.0f%%", progress * 100)
