Run Modal after async call made - swift

Question

I am new to Swift Mac App development, I am having troubling going from a login window to showing the main window after a login URLRequest, and making another URLRequest in the new main window. If I just go from one window without making the login URLRequest, it works fine.
func loadMainView() {
self.view.window?.close()
let storyboard = NSStoryboard(name: "Main", bundle: nil)
let mainWindowController = storyboard.instantiateController(withIdentifier: "MainViewController") as! NSWindowController
if let mainWindow = mainWindowController.window {
let application1 = NSApplication.shared()
application1.runModal(for: mainWindow)
}
}
func tryLogin(_ username: String, password: String ) {
Staff.login(username: self.username.stringValue, password: self.password.stringValue) { (completed, result, staff) in
// DispatchQueue.main.async {
if completed {
if result == .Success && staff != nil {
DispatchQueue.main.async(execute: {
self.loadMainView()
})
} else {
self.dialogOKCancel(message: "Error", text: "Your credentials are incorrect")
}
} else {
print("error")
}
}
}
HTTPSConnection.httpGetRequestURL(token: token, url: digialOceanURL, mainKey: mainKeyVal) { ( complete, results) in
DispatchQueue.main.async {
if complete {
}
}
}
I have tried calling the self.loadMainView() without the execute, but still not luck.
Any help appreciated. Thanks

Don't run your main view in modal, modal should be used for dialogs. So you can run login view in modal (and finish it by calling stopModal on the application). In that case you could use smth like loadLoginView which will have similar implementation to your current loadMainView (but without this self.view.window?.close() call. And main view would be loaded from nib on application launch. But you have to post some more code (how your app initalization looks like?) to get help on that.
