When again can you set properties for Storyboard objects?

Have a single view controller that operates for both an iPhone storyboard and an iPad storyboard. The view controller scenes for each include a UIView subclass with writeable properties necessary to create a special view.

I can successfully set the properties for the subclass in the view controllers viewDidLoad for the iPhone but the properties are not successfully set for the iPad and the subclass obviously does not perform as designed. Included below are abstracted console listings (for simulators) that show the iPhone the subclass is inited with coder slightly before the viewDidLoad for both devices, so I would think I was safe. When I test the subclass without the rest of the app, it works for both devices in the simulators.

So, again (because I think I used to know this), when can you reliably set properties for storyboard objects within a scene?

OK, would still like to know when one can set properties of a child view of a view controller placing the view in IB, but solved the problem by just instantiating the subclass programmatically in viewDidLoad the old-fashioned way 😉
