Updates should be required only when specific apis or features are deprecated and the app in question uses those.
But there probably isn't an easy way to test whether an app uses them. Aside from literally going through the binary, looking for those calls or something.

Xcode tells you what deprecated calls you are using every time you do a fresh build. The list varies by which minimum iOS version you state.
Xcode also tells you if your project settings need an update, and will do it for you.
You should always be able to do a fresh build, or your app is effectively abandoned.
