Answer 1

You can subclass the view to customize it.

Answer 2

This function finds the search field. Hopefully it may point the way for you to proceed.

extension ABPeoplePickerView {
  func searchField () -> NSSearchField?{
    for v in self.subviews[0].subviews {
      if v.isKind(of: NSSearchField.self) { return (v as! NSSearchField) }
    }
    return nil
  }
}
