I am able to return the screen size using:

- (void) getScreenResolution {



    NSArray *screenArray = [NSScreen screens];

    NSScreen *mainScreen = [NSScreen mainScreen];

    unsigned screenCount = [screenArray count];

    unsigned index  = 0;



    for (index; index < screenCount; index++)

    {

      NSScreen *screen = [screenArray objectAtIndex: index];

      NSRect screenRect = [screen visibleFrame];

      NSString *mString = ((mainScreen == screen) ? @"Main" : @"not-main");



      NSLog(@"Screen #%d (%@) Frame: %@", index, mString, NSStringFromRect(screenRect));

    }

}

Output:

Screen #0 (Main) Frame: {{0, 4}, {1344, 814}}

Is there a way to format {1344, 814} to 1344x814?

Edit:

This works perfectly:

- (NSString*) screenResolution {



    NSRect screenRect;

    NSArray *screenArray = [NSScreen screens];

    unsigned screenCount = [screenArray count];

    unsigned index  = 0;



    for (index; index < screenCount; index++)

    {

        NSScreen *screen = [screenArray objectAtIndex: index];

        screenRect = [screen visibleFrame];

    }



    return [NSString stringWithFormat:@"%.1fx%.1f",screenRect.size.width, screenRect.size.height];

}

NSLog(@"%fx%f",screenRect.size.width, screenRect.size.height);

Finding the screen size in Mac OS is very simple:

NSRect e = [[NSScreen mainScreen] frame];

H = (int)e.size.height;

W = (int)e.size.width;

In Swift 4.0 you can get the screen size of the main screen:

if let screen = NSScreen.main {

    let rect = screen.frame

    let height = rect.size.height

    let width = rect.size.width

}

If you look for the size of the screen with a particular existing window you can get it with:

var window: NSWindow = ... //The Window laying on the desired screen

var screen = window.screen!

var rect = screen.frame

var height = rect.size.height

var width = rect.size.width

For those guy who are looking for a way to get screen resolution:

If you are programming a window based app, you can simply get the resolution from _window.screen.frame.size

edit/update

Swift 4

NSScreen.main?.frame         // {x 0 y 0 w 1,920 h 1,200}

NSScreen.main?.frame.width   // 1,920.0

NSScreen.main?.frame.height  // 1,200.0 

Swift 3.x

NSScreen.main()?.frame         // {x 0 y 0 w 1,920 h 1,200}

NSScreen.main()?.frame.width   // 1,920.0

NSScreen.main()?.frame.height  // 1,200.0 

Swift 2.x

NSScreen.mainScreen()?.frame         // {x 0 y 0 w 1,920 h 1,200}

NSScreen.mainScreen()?.frame.width   // 1,920.0

NSScreen.mainScreen()?.frame.height  // 1,200.0

Swift 3 solution:

NSScreen.main()!.frame
