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

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. Thanks let context = NSGraphicsContext.current()?.cgContext  override func draw(_ dirtyRect: NSRect) {         super.draw(dirtyRect)        ** let context = NSGraphicsContext.current()?.cgContext**         let length = CGPoint(x: 100, y: 100)         let p1 = CGPoint(x: 200, y: 200)         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 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: 0)         q.draw(at: center, withAttributes: attr as [NSAttributedString.Key : Any])     } }

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])     } }

How to sort NSTableView Date Column?
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                }            }

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?

Also, if there is a better/newer way to code this I am open to changing the code. Thanks

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)     } }

How to add an IBAction to a macOS tableView Cell
I have a macOS tableview I have a textfield as a column along with an IBAction code to capture the data from this field. I wanted to add continuous spell check for this column . So, I decided to change the column from a TextField to a ScrollView to take advantage of the continuous spell check. Using Xcode 14 I changed the Cell to a custom Cell. The custom cell has a scrollview object as the object because I want to take advantage of the built in continuous spell checking instead of using a textfield. All is well with this implementation until I tried to add a IBAction code for when I enter text in the scrollview/textView field. There does not seem to be a way to capture the text? Am I trying to do something that can't be done or is there a way to add continuous spell check to a textField?

macOS Xcode 14.2 app applicationwillterminate function is not called
I want to put some code to be run when my app terminates but the following:        func applicationWillTerminate(_ aNotification: Notification) {             // Insert code here to tear down your application             print("Termination Code")         } in the AppDelegate class is not called, any ideas how to fix this issue. I saw this posts https://developer.apple.com/forums/thread/126418 but I do not have an info.plist. I think the info.plist is not longer needed. The following doc does not have much to say about this?? https://developer.apple.com/documentation/appkit/nsapplicationdelegate/1428522-applicationwillterminate
