I have the latest version of xcode and xamarin/visual studio for mac. Even with older version, though, when I try to modify storyboards in Xcode I start to get "not key code compliant" for verious views. Even if I haven't modified that particular view controller. The biggest issue that I am having is that the views are not resizing themselves properly for iPhone SE, 8 or 8 plus. For the most part things are ok on 8, but when I go in to make modifications to make them work for the other two something always gets screwed up. I am at my wits end. Currently I am trying a complete uninstall and reinstall of the tools, but I am not holding my breath. Any help would be much appreciated!
