Are you excited to bring this thing back from the dead? So are we. Let's use default configuration and see what we get out-of-the-box:

let progressView = ProgressView(frame: CGRect(x: 0, y: 0, width: 360, height: 30))
progressView.animateProgress(to: 0.8)

Do you think it's way too retro? Let's try to make it more modern:

let progressView = ProgressView(frame: CGRect(x: 0, y: 0, width: 360, height: 30))

// Configure
progressView.layer.cornerRadius = 10
progressView.layer.borderColor = UIColor.black.cgColor
progressView.trackColor = .white
progressView.separatorColor = .black
progressView.progressColor = UIColor(
  red: 218/255,
  green: 236/255,
  blue: 255/255,
  alpha: 1

// Set progress
progressView.animateProgress(to: 0.8)

Not a fan of those separators? Let's try without them:

let progressView = ProgressView(frame: CGRect(x: 0, y: 0, width: 360, height: 30))

// Configure
progressView.numberOfSteps = 0
progressView.progressInset = .zero
progressView.layer.cornerRadius = 15
progressView.layer.borderColor = UIColor.white.cgColor
progressView.trackColor = .black
progressView.progressColor = .white

// Set progress
progressView.animateProgress(to: 0.8)

The options are limitless. Think big, now it's your turn to make the progress bar great again.
