how to handle applicationShouldHandleReopen in a Non-Document based Storyboard Application

Question

The best I have been able to figure out is:

func applicationShouldHandleReopen(sender: NSApplication, hasVisibleWindows flag: Bool) -> Bool {

    if !flag{
          


        

Answer 1

In case you are looking for a cocoa-based solution for non-document apps. This is the equivalent of Adam's second solution.

- (BOOL)applicationShouldHandleReopen:(NSApplication *)theApplication hasVisibleWindows:(BOOL)flag
{
   if(!flag)
   {
       for(id const window in theApplication.windows)
       {
           [window makeKeyAndOrderFront:self];
       }
   }
   return YES;
}

Answer 2

Swift 3: In AppDelegate.swift add a variable of type NSWindow

lazy var windows = NSWindow()

and implement applicationShouldHandleReopen:

func applicationShouldHandleReopen(_ sender: NSApplication, hasVisibleWindows flag: Bool) -> Bool {
    if !flag {
        for window in sender.windows {
            window.makeKeyAndOrderFront(self)
        }
    }

    return true
}

Or using forEach:

func applicationShouldHandleReopen(_ sender: NSApplication, hasVisibleWindows flag: Bool) -> Bool {
        if !flag {
            sender.windows.forEach { $0.makeKeyAndOrderFront(self) }
        }

        return true
    }
