Answer 1

Try this.

if #available(iOS 9.0, *) {
  UITextField.appearance(whenContainedInInstancesOf: [UISearchBar.self]).defaultTextAttributes = [NSForegroundColorAttributeName: UIColor.green]
  } else {
  // Fallback on earlier versions
}

Answer 2

此版本适用于最新的Swift版本

UITextField.appearance(whenContainedInInstancesOf: [UISearchBar.self]).defaultTextAttributes = [NSAttributedStringKey.foregroundColor.rawValue: UIColor.white] as [String:Any]
