Reopen/reinitialize the Main window when click on the App Icon

Proposal: Reopen/reinitialize the Main window when click on the App Icon

Summary

When closing the App window the application is still running. This is expected MacOS behaviour. Usually when you click on the App icon it opens a new window e.g. VSCode open an empty project.

For react-native-macos it would make sense to by default open the main window.

Motivation

For iOS the behaviour is different. There is only one "window" and it can't be closed except for closing the whole app.

Open Questions

Not sure if this is React-Native specific, Xcode or a combination of both. I'm very new to Xcode, but I was thinking having a good default in the react-native-macos template would be great.

Did a bit more research and found out that this needs to be used: https://developer.apple.com/documentation/appkit/nsapplicationdelegate/1428638-applicationshouldhandlereopen

This may be a mismatch between what a default macOS app does and the actual default that users expect. The right thing is what you're describing here. Good suggestion.

Try https://developer.apple.com/documentation/appkit/nsapplicationdelegate/1428491-applicationopenuntitledfile Sounds strange, but works for me ;)

@holtwick @chrisglein reinitialising the whole Storyboard works, but I'm not sure it's the best way to solve it. Feedback very welcome!

- (BOOL) applicationShouldHandleReopen:(NSApplication *)sender hasVisibleWindows:(BOOL)flag {
  if (!flag) {
    NSStoryboard *storyboard = [NSStoryboard storyboardWithName:@"Main" bundle:nil];
    NSWindowController *controllerWindow = [[NSWindowController alloc] init];
    controllerWindow = [storyboard instantiateInitialController];
    [controllerWindow showWindow:self];
  }
  return flag;
}

@nikgraf solution works, it would be great to have this behavior by default I think.

After so much research I found this solution and it's working. Thank you!
