Quartz (usually referred to as Core Graphics) isn’t recommended anymore on Macs.

Developers should be using SwiftUI now, which is a completely different approach:

class HelloWorldView: NSView {
    override func draw(_ dirtyRect: NSRect) {
        super.draw(dirtyRect)

        // Drawing code here.
        guard let context = NSGraphicsContext.current?.cgContext else { return }

        // Set text attributes
        let attributes: [NSAttributedString.Key: Any] = [
            .font: NSFont.systemFont(ofSize: 24),
            .foregroundColor: NSColor.black
        ]

        // Create the string
        let string = NSAttributedString(string: "Hello World", attributes: attributes)

        // Draw the string
        string.draw(at: CGPoint(x: 20, y: 20))
    }
}

Here’s the same thing with SwiftUI:

struct HelloWorldView: View {
    var body: some View {
        Text("Hello World")
            .font(.system(size: 24))
            .foregroundColor(.black)
            .padding()
    }
}
