I have an iPhone-only app which needs to become universal. I selected the target and changed Deployment Info > Devices from "iPhone" to "Universal". The blog post I found says Xcode asks you what to do. But it didn't ask anything. When I run the app on iPad it just crashes with no log in console.
The problem can be that my project doesn't use any xib files. Is there a resource that details what exactly you need to configure to make an app universal by hand?
