iOS iOS app updates and unsupported devices

[genebrecht]

My app is already available on App Store and there are users with older devices such as iPhone 4/4S and older iOS version (i.e iOS 7). But it seems that Xcode 8 only supports up to iOS 8. What would happen to those users with outdated devices and iOS versions installed if I build my app update with Xcode and send the update to iTunes? Are they simply not getting new updates?

If you change the minimum os version or other requirements during an update then users that don't meet the new requirements can't get the update. They don't lose the already installed version of the app if they have it. If they never had your app before then they simply can't install it.

Most devices of recent vintage can go up to iOS 9.3.5 or the latest 12 and these are all free upgrades. I don't recommend trying to make your app run on older OS versions. Very little bang for the buck there and it will be harder than you think.
