Create an indicator like this:

ActivityIndicatorView(type: .default)

where
type - value from ActivityIndicatorView.IndicatorType enum

You may alter it with standard SwiftUI means like this:

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

Or specify another indicator type:

ActivityIndicatorView(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(count: 8)

.arcs(count: 3, lineWidth: 2)
