    var body: some View {
      
    if  (UserDefaults.standard.set(self.username, forKey: "Username") != nil) {

Use @AppStorage to store and get values for user defaults.

@AppStorage("Username") var username: String = ""

or you can use also use UserDefaults.

if !UserDefaults.standard.string(forKey: "Username") {
     login()
} else {
    home()
}
