Can the speed of filling animation (Progress) be modified?

[HadiYaac]

If I want to speed up or slow down the speed of the filling progress animation, is that doable? If yes please help

In my example scenario, you can decrease progress value,
counter += 0.007
progressBar.progress = counter

Or you can increase timer interval,
Timer.scheduledTimer(timeInterval: 0.3, target: self, selector: #selector(ticker), userInfo: nil, repeats: true)

It's all about where and for what are you using it. like something for downloading or something for process.
give me some more detail and i'll give you a proper ans.
