If we have an application that is currently live on the App Store, compatible with only iPhone devices, and we make an update compatible with both iPhone and iPad devices (Universal) what will happen?
I can think of two possibilities:
- the app will not be updated – the updates will require app binaries only for iPhone devices;
- there is no problem in adding the iPad support.
I did not see a clear answer in Apple’s Guides. There were some discussions in the links below:
iOS Universal App question
iPhone/iPad – Breaking universal into iPhone app only
iOS: Universal App – Release as iPhone only
Does anyone have the answer, with references to Apple Guides? I need to be sure this is possible.
Second answer: it’s absolutely not a problem. Those who downloaded your app on an iPad and run in “iPhone simulator” mode on their iPad, will be happily pleased to see they now have a full-fledged app. Users on an iPhone won’t notice a difference.
Edit:
Closest I can find in Apple’s doc is https://developer.apple.com/library/ios/#documentation/iPhone/Conceptual/iPhoneOSProgrammingGuide/AdvancedAppTricks/AdvancedAppTricks.html
It states that “The following sections highlight the changes you must make to an existing app to ensure that it runs smoothly on any type of device”: essentially, update the info.plist and rework your view and view controllers.
