I have this code which is working correctly. However I would like to simplify the code to make it much more streamlined.

import Cocoa  class ViewController: NSViewController, NSTextFieldDelegate {      @IBOutlet weak var TF1: NSTextField!     @IBOutlet weak var TF2: NSTextField!     @IBOutlet weak var TF3: NSTextField!     @IBOutlet weak var Bt1: NSButton!     @IBOutlet weak var Bt2: NSButton!     var activeTextField = NSTextField()      override func viewDidLoad() {         super.viewDidLoad()         TF1.delegate = self         TF2.delegate = self         TF3.delegate = self     }      @IBAction func Bt1Pressed(_ sender: NSButton) {         if TF1.currentEditor()?.selectedRange.length == 0{             TF1.stringValue = "B1 Pressed"             print("IS SeletedAll")         }          if TF2.currentEditor()?.selectedRange.length == 0{             TF2.stringValue = "B1 Pressed"             print("IS SeletedAll")         }          if TF3.currentEditor()?.selectedRange.length == 0{             TF3.stringValue = "B1 Pressed"             print("IS SeletedAll")         }      }      @IBAction func Bt2Pressed(_ sender: NSButton) {         if TF1.currentEditor()?.selectedRange.length == 0{             TF1.stringValue = "B2 Pressed"             print("IS SeletedAll")         }          if TF2.currentEditor()?.selectedRange.length == 0{             TF2.stringValue = "B2 Pressed"             print("IS SeletedAll")         }          if TF3.currentEditor()?.selectedRange.length == 0{             TF3.stringValue = "B2 Pressed"             print("IS SeletedAll")         }      }        override var representedObject: Any? {         didSet {         // Update the view, if already loaded.         }     }   } 

My thought was to some how set activeTextField with the selected field and then be able to pass the value back to the correct field with something like this.

@IBAction func Bt1Pressed(_ sender: NSButton) {  if activeTextfield.currentEditor()?.selectedRange.length == 0 {     activeTextfield.stringValue = "B1 Pressed"  } }
