Window will not close even if self.view.window?.close() is used

Question

So I am trying to make a macOS window close after a selected period of time. I read online that I could use self.view.window?.close to make it disappear. So far, that is not working.

Do any of you have any tips?

Also, I want it to open another window after the 1st one closes. So I don't want it to quit the app entirely.

EDIT: I found out by using print(self.view.window) was set to nil. What does that mean and how do I fix it?

Are you sure that `self.view.window` isn't `nil`? – rmaddy Mar 13 '19 at 18:17 — rmaddy, Mar 13 '19 at 18:17

this is redundant code but sometimes I have managed to solve this issue like this:

// Window reference
var window: NSWindow?  

// After window is displayed, get the handle to it
window = self.view.window!

// To dismiss it try
window?.performClose(nil) // nil or empty value

Hope it helps.

Your code failed on 'window = self.view.window!' with: "Thread 1: Fatal error: Unexpectedly found nil while unwrapping an Optional value" – Intelligent Pickle Mar 13 '19 at 19:07
@TheUbuntuMaster you just need to move your code from viewDidLoad to `viewWillAppear` or `viewDidAppear` methods. – Leo Dabus Mar 13 '19 at 19:55
@LeoDabus How do you do that? – Intelligent Pickle Mar 13 '19 at 20:03
