swift 3 present UIViewController: nib but the view outlet was not set

Question

Update(3)

I have the following code:

This works if I wait in the debugger:

And if I dont:

A view can only be associated with at most one view controller at a time!

@IBAction func openTestViewController(_ sender: Any) {
    let b = Bundle(identifier: "com.test")
    let m = MultipleListViewController(nibName: "MultipleListViewController", bundle: b)
    self.present(m, animated: true, completion: nil)
}

This does not work; error: `

A view can only be associated with at most one view controller at a time!

@IBAction func openTestViewController(_ sender: Any) {
    DispatchQueue.main.async {
    let b = Bundle(identifier: "com.test")
    let m = MultipleListViewController(nibName: "MultipleListViewController", bundle: b)
    self.present(m, animated: true, completion: nil)
        }
}

Note: The reason I do Bundle(identifier: "com.test") is because I have it in a framework.

This only works if: 1. I set a breakpoint 2. And wait for it to load - and make sure that I can see it with the little preview eye when debugging.

How can I/should i wait for it in code?

If you remove the bundle in `MultipleListViewController ` initialization works fine? — mhergon, Feb 22 '17 at 13:46
Thanks, but no then I get: 'Could not load NIB in bundle: 'NSBundle. Note; I am loading from a framework that I also created. — Chris G., Feb 22 '17 at 13:48
Can you try to load `MultipleListViewController` in new project and check if works separately? `"MyViewController"` exists? — mhergon, Feb 22 '17 at 13:49
Good question: I have this in a seperate project just for testing the framework. And it is strange that it do work when I just wait for it in the debugger? — Chris G., Feb 22 '17 at 13:51
Are in the main thread? What happens if you wrap the code inside `DispatchQueue.main.async { }`? What happens if you wrap only the last line? — Yonat, Feb 22 '17 at 13:52
Then I get: 'A view can only be associated with at most one view controller at a time!' — Chris G., Feb 22 '17 at 13:54
Where is this code in your project? We need some more context. — Giuseppe Lanza, Feb 22 '17 at 13:56
What happens if you replace the second line with `let m = MultipleListViewController()` ? — Yonat, Feb 22 '17 at 13:59
@Yonat I get a black screen, meaning that it does not load the nib file. — Chris G., Feb 22 '17 at 14:05
