我没有看到UIProgressViewXcode 11.0/Swift 5/iOS 13的动画：

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)
}

此代码适用于 iOS <12，但不适用于 iOS 13。我错过了什么吗？
