title: UIProgressView not animating progress on iOS 13
body: <p>I am not seeing the animation of a <code>UIProgressView</code> with Xcode 11.0/Swift 5/iOS 13:</p>
  
  <pre><code>private let timerProgressView: UIProgressView = {
      let timerProgressView = UIProgressView()
      timerProgressView.progressTintColor = white
      timerProgressView.trackTintColor = .black
      timerProgressView.setProgress(1.0, animated: false)
      return timerProgressView
  }()
  
  private func triggerProgressView() {
      UIView.animate(withDuration: viewModel.timeLimit, delay: 0.0, options: .curveLinear, animations: { [weak self] in
          self?.timerProgressView.setProgress(0.0, animated: true)
      }, completion: nil)
  }
  </code></pre>
  
  <p>This code works on iOS &lt;12 but not on iOS 13. Am I missing something?</p>
