			=Get Coordinates of TextField or any View in SwiftUI=

			Here is a demo of how specific view coordinates can be read (see helpful comments inline)

			<pre>
			struct DemoReadViewOrigin: View {

			@State private var someNumber1 = "1000"
			@State private var someNumber2 = "2000"
			//bunch more

			@State private var enteredNumber = "Some Text at the Top"
			@State var value: CGFloat = 0

			var body: some View {
			ScrollView {
			VStack {
			Spacer()
			Text("\(enteredNumber)")
			Spacer()

			Group { //1
			TextField("Placeholder", text: $someNumber1)
			.keyboardType(.default)
			.textFieldStyle(RoundedBorderTextFieldStyle())
			.background(GeometryReader { gp -> Color in
			let rect = gp.frame(in: .named("OuterV")) // < in specific container
			// let rect = gp.frame(in: .global) // < in window
			// let rect = gp.frame(in: .local) // < own bounds
			print("Origin: \(rect.origin)")
			return Color.clear
			})

			//this does not work
			.onTapGesture {
			}

			TextField("Placeholder", text: $someNumber2)
			.keyboardType(.default)
			.textFieldStyle(RoundedBorderTextFieldStyle())
			}//group 1

			//bunch more

			Button(action: {
			self.enteredNumber = self.someNumber1
			self.someNumber1 = ""
			// UIApplication.shared.endEditing()
			}) {
			Text("Submit")
			}
			.padding(.bottom, 50)

			}//outer v
			.coordinateSpace(name: "OuterV") // << declare coord space
			.padding(.horizontal, 16)
			.padding(.top, 44)

			}//Scrollview or Form
			// .modifier(AdaptsToSoftwareKeyboard())
			}
			}
			</pre>

	OK Got exercise working but status bar truncates length of time. Setting a length of 53 seems to be th e max - any larger an the display fails. Have not worked out how to user a smaller font so it will not overflow the space available.		OK Got exercise working but status bar truncates length of time.

			=Mouse Location=

			From 2015...

			* https://stackoverflow.com/questions/31931403/getting-mouse-coordinates-in-swift

			If you would like to monitor events on any window when your app is active, you can add a LocalMonitorForEvents matching mouseMoved mask and if it is not active a GlobalMonitorForEvents. Note that you need set to your window property acceptsMouseMovedEvents to true

			</pre>
			import Cocoa

			class ViewController: NSViewController {
			lazy var window: NSWindow = self.view.window!
			var mouseLocation: NSPoint { NSEvent.mouseLocation }
			var location: NSPoint { window.mouseLocationOutsideOfEventStream }
			override func viewDidLoad() {
			super.viewDidLoad()
			NSEvent.addLocalMonitorForEvents(matching: [.mouseMoved]) {
			print("mouseLocation:", String(format: "%.1f, %.1f", self.mouseLocation.x, self.mouseLocation.y))
			print("windowLocation:", String(format: "%.1f, %.1f", self.location.x, self.location.y))
			return $0
			}
			NSEvent.addGlobalMonitorForEvents(matching: [.mouseMoved]) { _ in
			print(String(format: "%.0f, %.0f", self.mouseLocation.x, self.mouseLocation.y))
			}
			}
			override func viewWillAppear() {
			super.viewWillAppear()
			window.acceptsMouseMovedEvents = true
			}
			}

			</pre>
			You can get the current mouse location in this way:

			Declare this in your view controller class:

			<pre>
			var mouseLocation: NSPoint? { self.view.window?.mouseLocationOutsideOfEventStream }
			</pre>

			Then, you can get the current mouse location and convert in your desired view coordinates:

			<pre>
			if let currentMouseLocation = self.mouseLocation{

			let pointInTargetView = self.targetView.convert(currentMouseLocation, from: self.view)

			}
			</pre>
