I have an iPhone app on the store that requires IO7. I have just developed a new iPad interface to make it a universal app. However I just realised that one feature on my iPad interface (presenting a split view controller via a modal segue) is IOS8 only. If I submit a new binary that has IOS8 as the deployment target will this happen (i hope) : Current users on IOS8.0 and above: Get an update and get to use it on iPad too Current users on IOS7 Get no update as (I'm hoping) the app store detects the new update is IOS8.0 minimum New users Have to have IOS8 or above to use the new universal app What I don't want: Current iPhone users get the update and it crashes/won't run as they don't have IOS8.0 The app store uses the original IOS7.0 minimum and ignores the deployment target in the new binary. People download the iPad app on IO7 iPads and it crashes.
