Is it possible to have conditional table columns for a swifui Table statement? Like for this code TableColumn("Image") { artPiece in if let imageData = artPiece.artImage.first, let image = UIImage(data: imageData!) { Image(uiImage: image) .resizable() .frame(width: 50, height: 50) } else { Image(systemName: "photo") .resizable() .frame(width: 50, height: 50) } } .customizationID("Image") TableColumn("Name", value: \.artName) .customizationID("Name") TableColumn ("Art ID", value: \.artPieceID) { artPiece in Text(String(artPiece.artPieceID)) } .customizationID("Art ID") have a conditional TableColumn for this part of my SWIFTDATA model var artDefinedFields: [ArtDefinedFields] = [] or if I change the variable string array to this var artDefinedFields: [ArtDefinedFields] = Array(repeating: ArtDefinedFields(), count: 10), initialize the array with "None" and only create a TableColumn when there is aArtDeginedFields value other than "None"

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?

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?

My environment is as follows: Xcode 12, macOS BS developing a macOS app. I have an IBOutlet from a IB window as @IBOutlet weak var imageView: NSImageView! So, I want to store imageView to a NSData object and then save the NSData object in my UserDefaults. Once I saved the Image in my UserDefaults I need to be able to decode or retrieve the image for use in other parts of the app. How is this done? Also, I have seen some cautions about converting an Image to NSData object and retrieving. It seems the retrieved image may not be 100% as it was originally. Is this true and if so why? Thanks

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

I have the following code: class ChartSeriesRow: ObservableObject {     var id = UUID()     var chartCategory: String     struct ChartSeriesData {         var chartEntry: [ChartData]     }     var chartSeries : ChartSeriesData     struct ChartData: Codable, Identifiable, Hashable {         var id = UUID()         let chartMonth: String         let chartSales: String     }     init() {         chartCategory = ""         chartSeries = ChartSeriesData(chartEntry: [ChartData(chartMonth: "01", chartSales: "10.0") ] )     } } How do I populate ChartSeriesData? I thought I could just add the following: However coding this way there is no append method. extension ChartSeriesRow {     func addRow(chartRow: ChartSeriesData){          ChartSeriesRow.ChartSeriesData.chartEntry.append(contentsOf: chartRow)     } }

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?

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?

Is there a way with code I can in a general routine, which gets activated with CMD+P that shows the name of the window that was previously in focus? If so, how is this done?

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?

Environment is macOS Monterey Xcode 13. Is there a way to change the behavior of a macOS NSTableView to have the row height change based on the contents of a column. As an example when populating the column data and the width of the content exceeds the width of the column to have the content wrap to an additional line, which of course the row height would have to change then as well. If so, how can this be done? Thanks

I am using the code below to learn more about drawing but I am getting an ambiguous error on the line not sure how to resolve this. Please advise how to code this.

I have the test code below which draws a box with some text in it. I would like to add an image to the drawing. The function getCompanyLogo returns an NSImage and I would like to then add this image to the drawing. I have read apple's archive doc at the Drawing with COCOA but do not see how to complete this. How is this done?

I have a date column in a macOS NSTableView column in YYYY-MM-DD format and when using the code below the sort does not sort way I want. When sorting ascending. It has the year correct but the month is in reverse order. See image below. How can I fix this?  func sortInvoices(invoiceColumn: String, ascending: Bool) {          enum SortOrder {             static let Date = "invoiceDateCreated"             static let Number = "invoicenumber"             static let Customer = "invoicecustomer"             static let Status = "invoicestatus"         }         switch invoiceColumn {         case SortOrder.Date:            invoices.sort { (p1, p2) -> Bool in                guard let id1 = p1.invoiceDateBilled, let id2 = p2.invoiceDateBilled else { return true }                if ascending {                    return id1 < id2                } else {                    return id2 < id1                }            }
