NSSavePanel missing "shouldRunSavePanelWithAccessoryView" key?

Question

I have the code below, which presents a save panel in my SwiftUI macOS App.

It needs to be able to display a file format picker, which is available in the standard accessory view.

However, the key to enable this view seems to be missing (Value of type 'NSSavePanel' has no member 'shouldRunSavePanelWithAccessoryView'), and I can't find any reference on when this was removed, or on an alternative.

Any smart people who know what's going on?

Code:

private func saveToFile() {
    appState.triggerViewUpdate.toggle()
    
    let panel = NSSavePanel()
    
    panel.nameFieldLabel = "Save adjusted image as:"
    panel.nameFieldStringValue = "adjustedimage.png"
    panel.canCreateDirectories = true
    panel.showsTagField = false
    panel.isExtensionHidden = false

    
    // this generates error "Value of type 'NSSavePanel' has no member 'shouldRunSavePanelWithAccessoryView'"
    panel.shouldRunSavePanelWithAccessoryView = true
    //
    
    
    if #available(OSX 11.0, *) {
        let allowedContentTypes = [UTType.png, UTType.jpeg]
        panel.allowedContentTypes = allowedContentTypes
    } else {
        let allowedFileTypes = [".png", ".jpeg"]
        panel.allowedFileTypes = allowedFileTypes // not sure if we need this
    }
    
    panel.begin { response in
        if response == NSApplication.ModalResponse.OK, let savePath = panel.url {
            if debug { print("savePath: \(savePath)") }

            let ciImage = applyFilters(textureIn: appState.imageTexture!)
            let cgImage = ciImage.asCGImage()
                            
            let nsImage = NSImage(cgImage: cgImage!, size: ciImage.extent.size)
            if nsImage.pngWrite(to: savePath) {
                print("File saved")
            }
        }
    }
}

See [shouldRunSavePanelWithAccessoryView](https://developer.apple.com/documentation/appkit/nsdocument/1515183-shouldrunsavepanelwithaccessoryv). It's a property of `NSDocument`. — Willeke, Feb 11 '21 at 10:37
Hi, yes i found that page but the property is missing from NSDocoment... — Michel Storms, Feb 11 '21 at 13:09
Is the app document based, are you using a subclass of `NSDocument`? — Willeke, Feb 11 '21 at 16:03
Not sure... started it though Xcode as a new macOS project for 10.15 and up... will check. — Michel Storms, Feb 11 '21 at 16:31

I managed to solve this using IKSaveOptions

    let panel = NSSavePanel()
    let options = IKSaveOptions(imageProperties: [:],
                                imageUTType: kUTTypeImage as String)!
    options.addAccessoryView(to: panel)

    panel.begin { response in
         if response == .OK, let savePath = panel.url {
            //...
         }
    }
