Hello:I've been studying up on How to populate an NSTableView with data from CoreData using a fetchRequest. A lot of the information I found is for Swift 3 and 4. I am using the latest Xcode Version with Swift 5.1. I've looked at the Apple Documentation, lots of tutorials, some responses in Apple CoreData Forum, and my implementation of tableViews with CoreData in my iOS app.Using what I've found, I constructed the code below to be able to display data from my CoreData store in an NSTableView (MAC OSx app).I set up the NSTableView inside of a ViewController, added the delegates, set the cell identifiers in interface builder, and setup for three columns.I think that what I've done below is too much (It absolutely can't be "not enough"). In any case , no data is displayed in the table View.I'd really appreciate some help with this.Thanks in advance. Please let me know what I don't need.import Cocoa import CoreData class RegistrationReportsViewController: NSViewController { override func viewDidLoad() { super.viewDidLoad() showRegisteredStudents() tableView.dataSource = self as?

Hello:I have the following code: There are no build errors, But the first text field "groupName" saves immediately (even without pressing the enter key) when I move to the next field, before the rest of the fields are entered. Then saves again when I press the SAVE button.

Hello I am trying to implement use of Radio buttons. After days of trying to get the values of my radio buttons (that is to see which one is checked and save value) I have had no success:Here is my code:var qValueNumbers = [0] let totalSum = Int() @IBAction func calcGroupScore(_ sender: NSButton) { answerItem = "" for item in results { if let record = item.value(forKey: "answer") as? String { answerItem.append(record) answerLabel.stringValue = answerItem print ("Answer is \(answerItem)") if let record = item.value(forKey: "qValue") as? String, var theValue = Int(record) { // groupScoreLabel.stringValue = qValueItem print ("qValueNumbers before append", qValueNumbers) func getScore (){ if (oneRadioButton != nil) && distractor1 == answerItem { print("button1 Selected") qValueNumbers.append(theValue) } if (twoRadioButton != nil) && distractor2 == answerItem { print("button2 Selected") qValueNumbers.append(theValue) } if (threeRadioButton != nil) && distractor3 == answerItem { print("button3 Selected") qValueNumbers.append(theValue) } if (fourRadioButton != nil) && distractor4 == answerItem { print("button4 Selected") qValueNumbers.append(theValue) } if (fiveRadioButton != nil) && distractor5 == answerItem { print("button5 Selected") qValueNumbers.append(theValue) } else{ // qValueNumbers.append(0) print ("The value of qValue is \(theValue)") } } getScore() qValueNumbers.append(theValue) let totalSum = qValueNumbers.reduce(0, +) print ("qValue is \(theValue)") print ("qValueNumbers after append", qValueNumbers) print ("Total is \(totalSum)") print ("Group score is \(totalSum)") } } }Here is my log output:Answer is 3qValueNumbers before append [0, 1530, 2650]The value of qValue is 2650qValue is 2650qValueNumbers after append [0, 1530, 2650, 2650]Total is 6830Group score is 6830Here is the problem:Whether or not a button is selected the "qValue" is still appended to qValueNumbers". If a radio button between 1 and 5 is selected and that button is the correct answer, then the qValue should be appended. As of now regardless of whether the checked button matches the correct answer a qValue is still appended instead of "0".Any help will nbe appreciated.

Hello:I am fetching records from CoreData in which there is an item called QValue. qValue is defined as a String but it has a number.qValue has different values (1000,1450, 1830, etc.)Each time the user calls for a record it returns a qValue in the data set.I want to Sum all the qValues returned in a session.I have tried many different ways but without success: for example (The error here is "Ambiguous reference to member '+' ")if let record = item.value(forKey: "qValue") as? String { qValueItem.append(record) groupScoreLabel.stringValue = qValueItem print ("qValue is \(qValueItem)") } if (oneRadioButton.state == NSControl.StateValue(rawValue: 1)) && distractor1 == answerItem { let arr = [qValueItem] let totalSum = arr.reduce(0, +) // Ambiguous reference to member '+' print("totalSum \(totalSum)")I want an increasing value with each record call which will be the "totalSum"Any help with implementing will be appreciated.

Hello:I have the following scenario:Using NSFetchRequest i get a count of items returned as:numberRecords = items.countI want to get a random record based on the number of records in "numberRecords".Now i can get a random value using : selector = Int.random(in: 0 ..< 355)But how can I use "numberRecords" to get a numerical value?Thanks.

Hello: I have the code below to try to get a random selection from CoreData store. However i'm getting a crash on line 33 with the error:Thread 1: EXC_BAD_ACCESS (code=1, address=0x232).

Hello:I have a function which when called, populates the labels and textView with data from a CoreData Fetch Request, for the user. Each time the function is called I want ONLY the new data in the UI controls. Presently, the new data is appended to the old which is totally unacceptable.How can I clear the old data so that the User sees ONLY the new data?Thanks for helping me with the solution.
