I had my storyboard setup so all the view sizes were inferred, this use to be 600x600, now Interface builder makes you chose a default size, and then takes forever to display this new size (my storyboard is quite large unfornutately), then all the autolayout constraints are all messed up, because the view size is no longer 600x600. This means my entire storyboard now needs to be redone for a specific iphone size? This is insane. Now I get tons of constraint violations, not to mention bad layout of my views.
Apple needs to be bring back the inferred size of 600x600 or a ton of app developers are not going to be able to ship apps unless they redue their entire storyboard.
Unbelievable that Apple did this.
Just curious, have you tried to free form the storyboard and set the size to 600 x 600 ?
