iOS6 performance problems in iOS7 compatible app

Question

My app worked beautifully on iOS6, but now I am deploying for it iOS6 and iOS7 through xCode 5 some users still running iOS6 have reported performance issues to me. I have not been able to recreate the issues on my one remaining iOS6 device, but it appears that some iOS6 users are experiencing memory problems which are causing the app's key process to terminate early.

I am debating whether to discontinue support for iOS6 for new releases and revert them to a stable pre-iOS7 version, using Apple's new feature for that. However, there is a cost involved as I am introducing some IAPs and monetization strategies to the new releases that ideally I would like available to all users.

Has anyone experienced similar performance issues or have any tips for handling this conundrum?

Answer 1

I've made the decision to discontinue support for iOS6 in new releases, and to roll-back those users to an earlier version. I do not have confirmation, but my strong suspicion is that apps built for iOS7 do not run as efficiently on iOS6 in terms of memory usage etc, and it is important that users running iOS6 get an app that works effectively.
