I understand by default SwiftData uses SQLite database but it can be configured to persist data in XML, binary and even in-memory databases. Does anybody know where SwiftData the SQLite database is located?

I am getting the following error on this line of code @Query(sort: \.id, order: .reverse) private var artList: [ArtInventory] Cannot infer key path type from context; consider explicitly specifying a root type So, I select fix and then the line of code then look like this @Query(sort: \<#Root#>.id, order: .reverse) private var artList: [ArtInventory] with this error Invalid component of Swift key path Some seems to have changed with the @Query macro in beta 5, which now needs a root type, but not sure how to proceed. Any ideas how to fix?

Don't see a link to download the Xcode project, starter and complete? How can I get it? Thanks Bob

Anybody else having problems with app icon on Xcode 12 not showing up for a macOS app?

The find and replace in project is not working for me in Xcode 14.2 on Ventura 13.2. When I enter the find text as well as the replace text the "Replace" and "Replace All" buttons remained grayed out. Is this a bug with Xcode or am I missing something? Please advise.

Using Interface Builder with Xcode 11 I have created two windows, when I activate the second window it opens as a tab in the main window. How do I change this to start a second window instead of a tab?

I have been looking for information on how to implement NSSpellChecker and NSTextCheckingController the last couple of days and have come up empty. Does anybody of some information using these two AppKit API's or even better an example on using them with an IBOutlet text field? I understand Apple use to make available the source code for textEdit app? Does anybody know if this is still the case? Thanks

I have a test app with a tableView that has a comboBoxCell for one of the columns in Xcode 12: The view controller code is as follows: // //  ViewController.swift //  ComboBoxExample // //  Copyright © 2016 yourCompany. All rights reserved. // import Cocoa class ViewController: NSViewController, NSComboBoxCellDataSource {     var states = ["Alabama", "Alaska", "Arizona", "Arkansas", "California", "Colorado", "Connecticut", "Delaware",                   "Florida", "Georgia", "Hawaii", "Idaho", "Illinois", "Indiana", "Iowa", "Kansas", "Kentucky",                   "Louisiana", "Maine", "Maryland", "Massachusetts", "Michigan", "Minnesota", "Mississippi",                   "Missouri", "Montana", "Nebraska", "Nevada", "New Hampshire", "New Jersey", "New Mexico",                   "New York", "North Carolina", "North Dakota", "Ohio", "Oklahoma", "Oregon", "Pennsylvania",                   "Rhode Island", "South Carolina", "South Dakota", "Tennessee", "Texas", "Utah", "Vermont",                   "Virginia", "Washington", "West Virginia", "Wisconsin", "Wyoming"]     @IBOutlet weak var itemComboCell: NSComboBoxCell!     override func viewDidLoad() {         super.viewDidLoad()         itemComboCell.usesDataSource = true         itemComboCell.dataSource = self         self.itemComboCell.completes = true         // Do any additional setup after loading the view.     }     override var representedObject: Any? {         didSet {         // Update the view, if already loaded.         }     }     func numberOfItemsInComboBoxCell(in comboBoxCell: NSComboBoxCell) - Int {       // anArray is an Array variable containing the objects         return states.count     }     func comboBoxCell(_ comboBoxCell: NSComboBoxCell, objectValueForItemAt index: Int) - Any {         return (states[index])     } } When running the example I get the following error: 2021-03-05 15:16:29.940373-0600 ComboBoxExample[40515:1914724] *** Illegal NSComboBoxCell data source (ComboBoxExample.ViewController: 0x600000e501b0).  Must implement numberOfItemsInComboBoxCell: and comboBoxCell:objectValueForItemAtIndex: How do I resolve this?

Using a combo box after a selection I want to get control to take some actions based on the selection after press tab or return in the field. I have tried a few controls like the one below: // textShouldEndEditing     func control(_ control: NSControl, textShouldEndEditing fieldEditor: NSText) - Bool {         print(#function,control.tag) But the above control only gets control if the field is edited. I want control once tab, an item selected or return is pressed while on the filed. How is this done?

How do you populate one column based on values of other column for a macOS app using Xcode 12 in a tableView? The value of the first column comes from a comboBox which I get control by using the following code connected to the comboBox: @IBAction func comboAction(_ sender: NSComboBox) {         print("Combo selected", sender.selectedTag(), sender.stringValue, sender.indexOfSelectedItem, sender.identifier as Any)         } Then base on the value of the comboBox column within the comboAction function I want to populate column 2. Can this be done? If so, how

I have the following code in a viewController: extension InvoicesDetailController: NSTableViewDelegate {     fileprivate enum CellIdentifiers {         static let lineItemLabelCell = "lineItemLabelCell"         static let lineItemDescCell = "lineItemDescCell"         static let lineItemAmountCell = "lineItemAmountCell"         static let lineItemQtyCell = "lineItemQtyCell"     }     fileprivate enum fieldIdentifiers {         static let lineItemLabel = "lineItemLabel"         static let lineItemDesc = "lineItemDesc"         static let lineItemAmount = "lineItemAmount"         static let lineItemQty = "lineItemQty"     }   func tableView(_ tableView: NSTableView, viewFor tableColumn: NSTableColumn?, row: Int) - NSView? {         let currentItem = invoiceItems[row]         var text: String = ""         var cellIdentifier: String = ""         let currentColumn = tableColumn?.identifier.rawValue         if currentColumn == fieldIdentifiers.lineItemLabel {             text = currentItem.lineItemLabel!             cellIdentifier = CellIdentifiers.lineItemLabelCell         }         if currentColumn == fieldIdentifiers.lineItemDesc {             text = currentItem.lineItemDesc!             cellIdentifier = CellIdentifiers.lineItemDescCell         }         if currentColumn == fieldIdentifiers.lineItemAmount {             text = currentItem.lineItemDesc!             cellIdentifier = CellIdentifiers.lineItemAmountCell         }         if currentColumn == fieldIdentifiers.lineItemQty {             text = currentItem.lineItemQty!             cellIdentifier = CellIdentifiers.lineItemQtyCell         }         if let cell = tableView.makeView(withIdentifier: NSUserInterfaceItemIdentifier(rawValue: cellIdentifier), owner: self) as? NSTableCellView {             print(cell.textField?.stringValue)             cell.textField?.stringValue = text             print(text, cell.textField?.stringValue)             return cell         }         return nil     } I have used this code (similar code in other places and it works fine, however in this case the tableView Cells are not being populated. When I look at this code using debugger the line if let cell = tableView.makeView(withIdentifier: NSUserInterfaceItemIdentifier(rawValue: cellIdentifier), owner: self) as? NSTableCellView always sets cell to nil? Since I don't see anything wrong with code I suspect there is an issue with the IB? Any ideas how to fix or how to debug further?

I am developing an macOS Xcode 12 app that requires printing. I have a basic understanding how to implement printing, I understand that I need to create a subclass of NSview to get going. However, I was wondering how to go about designing the report? Is this done with interface builder like designing a window layout or is all done with code, ie supplying position (x,y), headings, font, graphics, font size.. etc. How is this done? Also, does anybody have any tutorials on this? I have one example but it is very minimal print out, basically it prints a tableview with two columns. I got this from Coca Programming chapter 27, Big Nerd Ranch.

I have a macOS app which was built using Xcode 13 and storyboard. I want to add swiftCharts to the app. Can I add swiftCharts code to this app and not have to migrate the storyboard UI to swiftUI? How can this be done? Thanks

class CustViewController: NSViewController { @IBOutlet weak var tableView: NSTableView! @IBOutlet weak var statusLabel: NSTextField! fileprivate var selectedOptionFromMenu = "" @objc var contacts:[Person] = [] @objc var backUpContacts:[Person] = [] @IBAction func printCustomers(_ sender: Any?) { I would like to call the printCustomers function in the CustViewController from another class (NSWindowController). How is this coded in the NSWindowController class? I tried the following: let printAction = CustViewController.printCustomers(<#T##self: CustViewController##CustViewController#> ) but don't know how to code argument in this and this may be not be the way to do this?

I have created programmatically a NSTableView with a couple of columns, this table view has 3 columns and I want to set headers for the columns to accomplish the same thing as you get when you selected headers in IB. I looked for some examples, found a few things but not really work for me. How is this done. It seems like this should be easy to code. This is an example of one of the examples I found. let headerCell = CustomTableHeaderCell.init(textCell: "123123") // let font = NSFont(name: "Arial", size: 22.0) // headerCell.stringValue = "firstname" // headerCell.font = font self.tableView.tableColumns[0].headerCell = headerCell But CustomTableHeaderCell is not found. How is this done?
