I used to code with XCode back on iOS 3 and 4, so I've been out of the game for a bit. I've gotten back into coding and got the app I want coded, however, I am having trouble with this storyboard interface building. I built the app using the Any / Any size class, and I took my UIWebView and I pinned it using Editor | Pin | and I clicked all the options (Trailing Space, Leading Space, Bottom Space, Top Space). For all my iphones / ipad this works amazingly well. However, i would like to add an additional uiwebview when using just an iPad since I have screen real estate. When I go to the size classes at the bottom and change it to Regular / Any, it affects my Any / Any size class, and my Pin constraints go away, and everything breaks. Can anyone help? Is this possible to do, to have one storyboard with different layouts for iPhone / iPad? Please help! Thanks!
