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

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

I connected Github to Xcode 13.2 (Monterey macOS) successfully, however I do not see any packages available when I select Github as the source. I did download Xcode 13.2 from the developers website and it did fix some problems I was having with Xcode from the App Store but did make any difference to the issue above. Anybody else have this issue with Xcode 13.2?

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

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

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?

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?

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])     } }

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.
