ProgressView(label: {
    Text("Loading")
        .font(.caption)
        .foregroundColor(.secondary)
    }
).progressViewStyle(.circular)

this is old version, you should update code like this :

import SwiftUI

struct ContentView: View {
    var body: some View {
        ProgressView(label: {
            Text("Downloading...")
                .font(.caption)
                .foregroundStyle(.blue)
        })
        .progressViewStyle(CircularProgressViewStyle(tint: .blue))
        .scaleEffect(2)
    }
}
