How to implement text using hyperlinks in SwiftUI

Motjaba Hosseni is right so far there is nothing that resembles NSAttributedString in SwiftUI. This should solve your problem for the time being:

import SwiftUI

struct ContentView: View {
    var body: some View {
        VStack {
            Text("By tapping Done, you agree to the ")
            HStack(spacing: 0) {
                Button("privacy policy") {}
                Text(" and ")
                Button("terms of service") {}
                Text(".")
            }
        }
    }
}

Use built-in function +, it looks like a charm:

import SwiftUI

struct ContentView: View {
    var body: some View {
        HStack {
            Button(action: {

            }) {
                Text("By tapping Done, you agree to the ")
              + Text("privacy policy")
                  .foregroundColor(Color.blue)
              + Text(" and ")
              + Text("terms of service")
                  .foregroundColor(Color.blue)
              + Text(".")
            }
            .foregroundColor(Color.black)
        }
    }
}
