Create a progress indicator like this:

ProgressIndicatorView(isVisible: $showProgressIndicator, type: .bar(progress: $progress))

where
showProgressIndicator - bool value you may change to display or hide the indicator
type - value from ProgressIndicatorView.IndicatorType enum

You may alter it with standard SwiftUI means like this:

ProgressIndicatorView(isVisible: $showProgressIndicator, type: .bar(progress: $progress))
     .frame(width: 50.0, height: 50.0)
     .foregroundColor(.red)

default - progress indicator looks like default iOS UIActivityIndicator.
bar - line progress bar with a Binding progress value and background color, default is Color.clear:

 ProgressIndicatorView(isVisible: $showProgressIndicator, type: .bar(progress: $progress, backgroundColor: .gray))
     .frame(height: 8.0)
     .foregroundColor(.red)

impulseBar - impulse line bar, works as bar indicator with an impulse effect.
dashBar - discrete line bar, with number of pieces, default is 8:

  ProgressIndicatorView(isVisible: $showProgressIndicator, type: .dashBar(progress: $progress, numberOfItems: 8))
     .frame(height: 8.0)
     .foregroundColor(.red)

circle - cirle progress indicator, with lineWidth and strokeColor:

   ProgressIndicatorView(isVisible: $showProgressIndicator, type: .circle(progress: $progress, lineWidth: 8.0, strokeColor: .red))
      .frame(height: 8.0)
      .foregroundColor(.red)
