Code in the IBAction should be like: let storyBoard = NSStoryboard(name: "Main", bundle: nil) as NSStoryboard let secondController = storyBoard.instantiateController(withIdentifier: "secondVC")     self.presentAsModalWindow(secondController, animated: true, completion: nil) Don't forget to remove the segue from the button.

@Frameworks Engineer  Unfortunately, all has not been fixed yet. No notification received when answer marked as correct.

I try the example, but the 'Range' and 'Comparative' show error: Unknown precedence group Names of groups may have changed to: RangeFormationPrecedence ComparisonPrecedence And this compiles: precedencegroup Additive { higherThan: RangeFormationPrecedence, Equivalence } precedencegroup Multiplicative { higherThan: Additive } // module A precedencegroup Equivalence { higherThan: ComparisonPrecedence // lowerThan: Additive // possible, because Additive lies in another module } infix operator ~ : Equivalence Which confirms what you say about the issue with lowerThan. I don't understand the reason why they need to be in different modules to allow lowerThan. And documentation is really minimal on this. Could be worth a bug report on documentation.

Could you explain more what you want to do ? what is main device ? An iPhone, iPad, Mac ? What is the other device ? Cant you use AirDrop to transfer data ? You tagged Interface builder ? Do you want to transfer day between 2 ViewControllers ?

Use NSAnimation. For instance, if you want to animate when clicking a button: @IBAction func startAnimation(_ sender: NSButton) { let fixedDuration = 5.0 // set duration as you want, in seconds NSAnimationContext.runAnimationGroup( { (context) in context.duration = fixedDuration             self.view.window?.animator().setFrame(CGRect(x: 0, y: 0, width: 200, height: 200), display: true, animate: true) }) }

Could it be that    nicely formatted printable attributed string.     requires images entitlement ? Could you try without the nice formatting ?

Does it occur as well on simulator ? Could you show the code for appending pages, so that we may try to reproduce and confirm ?

import SwiftUI struct ContentView: View { var body: some View { NavigationView { NavigationLink(destination: NextContentView()){ Text("Next View") } } } } Declare a state var and have a test: import SwiftUI struct ContentView: View {     @State var firstPass: Bool = true   var body: some View { NavigationView {             if firstPass  { NavigationLink(destination: NextContentView()){ Text("Next View") } } else { NavigationLink(destination: CurrentView()){ Text("Other View") } } } } }

You have to do some computation. Here is a table which gives all devices size information. h t t p s : / / w w w.ios-resolution.com Let's consider an example: From screen physical Diagonal (phD), you can compute physical width (phW) and height (phH): we have equation : phW*phW + phH * phH = phD * phD. // Pythagore physical dimensions are proportional to logical dimensions phW = logW * x phH = logH * x Hence we get : x = phD / sqrt(logW*logW + logH * logH) phW = phD / sqrt() physWidth = x * logicalWidth Now that you have physical height and width of screen, as well as logical dimensions, it is easy to compute physical size of UI element: if it is h and w (in points) itemPhyWidth = w * physWidth / logicalWidth, or with previous formulae itemPhyWidth = w * x itemPhyHeight h * x Hope that helps.

Some computation on an example, on iPhone 12, a label with 34 points height: x = 6.06 / √(390390 * 844844) = 0.0065" = 0.0165 cm h = 34 * x = 0.56 cm

Did you try to use menuBarVisible ? https://developer.apple.com/documentation/appkit/nsmenu/1518236-menubarvisible

Try the following let usableHight = NSMenu.menuBarVisible() ? totalHight - 23 : totalHight Here is a simple test that works: let totalHeight = 400 var usableHeight = NSMenu.menuBarVisible() ? totalHeight - 23 : totalHeight print(usableHeight) NSMenu.setMenuBarVisible(false) usableHeight = NSMenu.menuBarVisible() ? totalHeight - 23 : totalHeight print(usableHeight)

Try the following let usableHight = NSMenu.menuBarVisible() ? totalHight - 23 : totalHight Here is a simple test that works: let totalHeight = 400 var usableHeight = NSMenu.menuBarVisible() ? totalHeight - 23 : totalHeight print(usableHeight) NSMenu.setMenuBarVisible(false) usableHeight = NSMenu.menuBarVisible() ? totalHeight - 23 : totalHeight print(usableHeight) yields: 377 hides menu bar 400

Did you manage to stop the animation with this solution ?

The correct practice on the forum is to post the question, in addition to the link.
