        Hello:

         

        I am trying to display some text in an NSTextView but thus far my efforts have been unsuccessful. Line 32, where I try to code to get the text to display causes a crash.  the debug error message is: 2019-11-21 20:09:38.876811-0500 ScorcentMasterReview[49322:25437243] -[NSTextView documentView]: unrecognized selector sent to instance 0x101094620.

         

        When I comment out line 32, the debug message is given below:

         

        Any help would be appreciated.

         

        Here is the code:

        @IBActionfunc getQuestion(_ sender: Any) {
                func runConsistencyCheck() {
                    do {
                       
                        try managedContext.save()
                    } catch {
                        print("An error occurred during consistency checking: \(error)")
                    }
                }
        
                   //      print ("Starting Fetch Function")
               guard let appDelegate = NSApplication.shared.delegate as? AppDelegate else {
                   
                                return
                        }
                      //     print ("Step Four")
                _ = appDelegate.persistentContainer.viewContext
                    
                let fetchRequest = NSFetchRequest(entityName: "SCQ")
                fetchRequest.returnsObjectsAsFaults = false
               
                  do {
                            items = try managedContext.fetch(fetchRequest)
                            print ("Record Returned is \(items)")
                        } catch let error as NSError {
                            print("Could not fetch. \(error), \(error.userInfo)")
                        }
                    for item in items {
                if let record = item.value(forKey: "question") as? String {
                        recordItem.append(record)
                  let stringvalue = "questionText: \(recordItem)"
                  questionView?.documentView?.insertText(stringvalue) //THIS LINE CAUSES A CRASH
                        print(stringvalue)
                            }
                }
                   for item in items {
                if let record = item.value(forKey: "distractor1") as? String {
                        distractor1Item.append(record)
                let stringvalue = "distractor1Label: \(distractor1Item)"
                        print(stringvalue)
                            }
                }
               
                     for item in items {
                    if let record = item.value(forKey: "distractor2") as? String {
                            distractor2Item.append(record)
                    let stringvalue = "distractor2Label: \(distractor2Item)"
                            print(stringvalue)
                                }
                    }
               
                     for item in items {
                    if let record = item.value(forKey: "distractor3") as? String {
                            distractor3Item.append(record)
                    let stringvalue = "distractor3Label: \(distractor3Item)"
                            print(stringvalue)
                                }
                    }
               
                     for item in items {
                    if let record = item.value(forKey: "distractor4") as? String {
                            distractor4Item.append(record)
                    let stringvalue = "distractor4Label: \(distractor4Item)"
                            print(stringvalue)
                                }
                    }
                     for item in items {
                    if let record = item.value(forKey: "distractor5") as? String {
                            distractor5Item.append(record)
                    let stringvalue = "distractor5Label: \(distractor5Item)"
                            print(stringvalue)
                                }
                    }

        Here is the debug results when I comment out line 32 where I try to get the output:
