Create an indicator like this:

ActivityIndicatorView(isVisible: $showLoadingIndicator, type: .default)

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

You may alter it with standard SwiftUI means like this:

ActivityIndicatorView(isVisible: $showLoadingIndicator, type: .default)
     .frame(width: 50.0, height: 50.0)
     .foregroundColor(.red)

Or specify another indicator type:

ActivityIndicatorView(isVisible: $showLoadingIndicator, type: .growingArc(.red, lineWidth: 4))
    .frame(width: 50.0, height: 50.0)

Each indicator type has a number of parameters that have reasonable defaults. You can change them as you see fit, but it is advised to not set them too high or too low.

default - iOS UIActivityIndicator style

.default(count: 8)

arcs

.arcs(count: 3, lineWidth: 2)

rotatingDots

.rotatingDots(count: 5)

flickeringDots

.flickeringDots(count: 8)

scalingDots

.scalingDots(count: 3, inset: 2)

opacityDots

.opacityDots(count: 3, inset: 4)

equalizer

growingArc - add custom color for growing Arc, the default value is Color.black

.growingArc(.red, lineWidth: 4)

growingCircle - no parameters
gradient - circle with angular gradient border stroke, pass colors like this:

.gradient([.white, .red], lineWidth: 4)
