How can I backup/restore an app (not just it's data) in iOS 10?

One of my apps got a big update with some mixed reviews, I'm interested in trying the new version, but won't do it if I can't roll back. For pre-iOS 9 systems, I heard you can backup ipa file from iTunes on PC, update the app on iPhone, and then if needed, overvrite back from iTunes and sync. But it doesn't work now - there's no ipa file for that app after iTunes sync.

What are my options? I've heard about programs like iMazing, but have a feeling that for iOS 10 it will just restore the app data and not the whole app version.

Solution 1:

Do an iCloud backup. iCloud backups are snapshots of the phone as it is. So you'll keep the old update and its data with an iCloud backup.

Do 1 right now and the other after the update.

After your testing, then you can over write that latest backup if need be based on your choice.

Solution 2:

We periodically switch between Xcode versions. What we do for Xcode is drop to the command line and tar up /Applications/Xcode.app

Sometimes, we'll rename Xcode.app to be a different name (e.g. Xcode_8.3.3.app) and have multiple versions installed at once.

This has worked for us for Xcode. We have not tried it on any other application.
