Downgrade Xcode SDK for app submission

Question

I submitted an update to the AppStore last week with the latest SDK - Xcode 5.1. However, I'm facing unexpected UI issues on iPhone 5S which I didn't previously find while testing on the iOS 64-bit simulator.

This seems clearly to be an SDK issue. I'm thinking the quickest solution now would be to submit another update with the older Xcode version 5.0.2.

Is this a good idea? Please suggest some pros & cons.

Answer 1

I found that the issue was because of the UIButton defined weak, which failed to get allocated on 64-bit devices for the app update submitted from Xcode 5.1 Interestingly, UIViews and UILabels declared in a similar way did NOT fail to get memory allocations.

Looking back at my original question, it was probably best to fix the issues under the latest SDK rather than reverting to an older version.
