How to populate an array within a Class Instance?
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)     } }

NSPredicate format for date comparison
I have the following code to search a tableView. The contains format works fine for string arguments however can't seem to find the correct format to work with date arguments.   @objc func invoiceSearch(sender:NSSearchField) {     //    print ("\(#function): \(sender.stringValue)")             let searchString = sender.stringValue             var predicate:NSPredicate = NSPredicate()             if searchString.isEmpty {                 invoices = self.backUpInvoices             }             else{       // search field contains data                 if (invoiceSearchField.cell as? NSSearchFieldCell)?.placeholderString == "All" {                     predicate = NSPredicate(format: "invoiceNumber contains %@ OR invoiceCustName contains %@ OR invoiceStatus contains %@ OR invoiceDateCreated >= %@",searchString,searchString,searchString,searchString)                 }                 else if (invoiceSearchField.cell as? NSSearchFieldCell)?.placeholderString == "invoice Number" {                     predicate = NSPredicate(format: "invoiceNumber contains %@",searchString)                 }                 else if (invoiceSearchField.cell as? NSSearchFieldCell)?.placeholderString == "invoice Customer"{                     predicate = NSPredicate(format: "invoiceCustName contains %@",searchString)                 }                 else if (invoiceSearchField.cell as?

NSSearchFieldCell)?.placeholderString == "Invoice Date"{                       predicate = NSPredicate(format: "invoiceDateCreated >= %@", searchString as CVarArg)                 }                 invoices = (self.backUpInvoices as NSArray).filtered(using: predicate) as! [Invoice]             }             invoiceCount = "Found \(items.count ) Invoices"             invoiceStatusLabel.stringValue = invoiceCount             self.tableView.reloadData()     } InvoiceDateCreated is defined by the following within a NSObject class: @objc   var invoiceDateCreated: Date? = Date() The error I get when trying to search on date is 2022-09-26 09:14:36.638553-0500 CashToMe[9107:6838576] [General] -[NSTaggedPointerString objCType]: unrecognized selector sent to instance I have read through the following documentation Apple Doc for NSPredicate How can I fix this. Also, if there is a better/newer way to code this I am open to changing the code. Thanks

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                }            }

Drawing an NSImage using COCOA Drawing
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? Thanks import Cocoa @IBDesignable class invoiceSectionTop: NSView {     override func draw(_ dirtyRect: NSRect) {         super.draw(dirtyRect)         let context = NSGraphicsContext.current?.cgContext         let length = CGPoint(x: 200, y: 50)         let p1 = CGPoint(x: 0, y: 50)         let shape = "square"         context!.beginPath()         context!.move(to: p1)         if shape == "line" {             let pointEnd = CGPoint(x: p1.x + length.x, y: p1.y + length.y)             context!.addLine(to: pointEnd)         } else if shape == "square" {             let p2 = CGPoint(x: p1.x + length.x, y: p1.y)             let p3 = CGPoint(x: p1.x + length.x, y: p1.y + length.y)             let p4 = CGPoint(x: p1.x, y: p1.y + length.y)             context!.addLine(to: p2)             context!.addLine(to: p3)             context!.addLine(to: p4)             context!.addLine(to: p1)         }         context!.setStrokeColor(red: 1, green: 1, blue: 1, alpha: 1.0)         context!.setFillColor(red: 0, green: 1, blue: 0, alpha: 1)         context!.setLineWidth(2.0)         context!.strokePath()         let image = getCompanyLogo()      // getCompanyLogo returns a NSImage object    //     NSGraphicsContext.current?.NSIm.draw(cgimage!, in: dirtyRect)         let textColor = NSColor(calibratedRed: 1, green: 1, blue: 1, alpha: 1.0)         let textColorB = NSColor(calibratedRed: 1, green: 1, blue: 1, alpha: 0.0)         let rect = CGRect(x: 200, y: 200, width: 30, height: 130)         let paragraphStyle = NSMutableParagraphStyle()         paragraphStyle.alignment = .center         let attr = [NSAttributedString.Key.paragraphStyle: paragraphStyle, NSAttributedString.Key.foregroundColor: textColor, NSAttributedString.Key.backgroundColor: textColorB, NSAttributedString.Key.font:NSFont.init(name: "HelveticaNeue-Thin", size: 14)]         let q: NSString = "hello, world"         let center = CGPoint(x: 0, y: 50)         q.draw(at: center, withAttributes: attr as [NSAttributedString.Key : Any])     } }

macOS TableView dynamic row height?
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

How to add headers programmatically to NSTableView
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?

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?

How to Activate Printer Panel
How do you activate the Printer Panel using a toolbar printer Icon in a macOS app like you get when I select File -> Print (CMD-P)? This is in a tableView view based screen. I have connected the first responder to "print:" thinking this might work but the printer Icon in the toolbar remains grayed-out. Also, tried connecting it to a @IBAction func but it still is grayed out. I am using Xcode 13 and 14 beta
