Connect new oulet from storyboard is always nil : I'm trying to connect new outlet from storyboard to UIViewController (by dragging), the outlet created as follow:

    @IBOutle var button2: UIButton!

- without "weak" key,
in runtime the outlet is nil, even if i add the "weak" key by my self and reconnect it again.

Its append in all the viewControllers in my project, only in one project.
(there are old outlets that work, the issue is only in new outlets create)

I tried to delete the DrivedData..
The files exist in the Target, in Compile Resources 
Im using Xcode 8 yet.

any answer?
