How to fake progress bar in swift?

Question

How can I fake a progress bar to make my app look a lot more complicated than it is...

for _ in 1...4{
    DispatchQueue.main.asyncAfter(deadline: .now() + 0.5) {
        print("test")
        self.Proggress.progress += 0.25
    }
}

This code is just loading a finished bar without simulating "progress."

Answer 1

let progressView = UIProgressView(progressViewStyle: .default)
for _ in 1...4{
    DispatchQueue.main.asyncAfter(deadline: .now() + Double(i) * 0.5) { 
        self.progressView.setProgress(0.25, animated: true)
    }
}

Answer 2

因为所有时间都在0.5的持续时间内同时触发，所以通过将for循环中的_替换for i

.now() + Double(i) * 0.5
