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])     } }

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?

I would like customize the nstableview alternate row color as light blue instead og light gray. How is this done? thanks

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])     } }

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                }            }

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?

[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

Environment: Xcode 14.1 beta 3 on macOS Ventura Beta 9. No longer need this, I found example of this. struct LocationsChart: View {     var body: some View {         Chart {             ForEach(seriesData, id: \.city) { series in                 ForEach(series.data, id: \.weekday) {                     BarMark(                         x: .value("Weekday", $0.weekday, unit: .day),                         y: .value("Sales", $0.sales)                     )                 }                 .foregroundStyle(by: .value("City", series.city))                 .position(by: .value("City", series.city))             }         }     }     let seriesData = [         (             city: "Cupertino", data: [                 (weekday: date(year: 2022, month: 5, day: 2), sales: 54),                 (weekday: date(year: 2022, month: 5, day: 3), sales: 42),                 (weekday: date(year: 2022, month: 5, day: 4), sales: 88),                 (weekday: date(year: 2022, month: 5, day: 5), sales: 49),                 (weekday: date(year: 2022, month: 5, day: 6), sales: 42),                 (weekday: date(year: 2022, month: 5, day: 7), sales: 125),                 (weekday: date(year: 2022, month: 5, day: 8), sales: 67)             ]         ),         (             city: "San Francisco", data: [                 (weekday: date(year: 2022, month: 5, day: 2), sales: 81),                 (weekday: date(year: 2022, month: 5, day: 3), sales: 90),                 (weekday: date(year: 2022, month: 5, day: 4), sales: 52),                 (weekday: date(year: 2022, month: 5, day: 5), sales: 72),                 (weekday: date(year: 2022, month: 5, day: 6), sales: 84),                 (weekday: date(year: 2022, month: 5, day: 7), sales: 84),                 (weekday: date(year: 2022, month: 5, day: 8), sales: 137)             ]         )     ] } func date(year: Int, month: Int, day: Int = 1) -> Date {     Calendar.current.date(from: DateComponents(year: year, month: month, day: day)) ??

Environment : macOS Ventura Xcode beta 14.1: I have the following chart I was using to learn about SwifUI Charts: I wanted to have different scales on the leading and trailing yaxis as well as have the first 3 bars to use leading scale and the last two bars use the trailing scale. Can this be done? If so, how? Thanks

From the class below how do I initialize chartEntry for the structure array? As it is below chartEntry is outside scope of init? class ChartSeriesRow: ObservableObject {     var id = UUID()     var chartCategory: String     struct chartSeriesData{         var chartEntry: [ChartData]     }     struct ChartData: Codable, Identifiable, Hashable {         var id = UUID()         let chartMonth: String         let chartSales: String     }     init() {         chartCategory = ""         chartEntry = chartSeriesData: [ChartData.chartMonth: "01",  ChartData.chartSales: "10.0"]     }      }

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)     } }

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?

For a macOS app using Xcode 14.1. I have a bar chart with two bars for each interval. See screen chart below. I want to change the "Invoice" and Payments" text I can't seem to find a modifier for the Legend text. How do you change the text color for SwiftUI Chart's legend text?

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

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.

I have a test project with a bar progress indicator create on Ventura with Xcode 14.3.1., It does not show the any animation until the @IBAction function completes. I want to show progress as it progresses not a just the end? Any ideas how to fix this? Below is my test project code.. // // ViewController.swift // ProgressTest // // Created by Bob on 6/5/23. // import Cocoa class ViewController: NSViewController { @IBOutlet weak var progressIndicator: NSProgressIndicator! // var progress: Double = 0.0 override func viewDidLoad() { super.viewDidLoad() // Do any additional setup after loading the view. } override var representedObject: Any? { didSet { // Update the view, if already loaded. } } @IBAction func progressStart(_ sender: Any) { // Start the progress animation progressIndicator.startAnimation(self) // Do some work here... // Do some work here... var progress: Double = 0.0 for _ in 0..<100 { // Update the progress value in a loop progress += 1.0 progressIndicator.doubleValue = progress // progress = Double(i) // progressIndicator.increment(by: 10) // progressIndicator.doubleValue = progress // Do some work here... } // Stop the progress animation progressIndicator.stopAnimation(self) } } thanks Bob
