As some of you have generously pointed out there is a bug in Couplings Designer 1.3 that was introduced with the iOS 7.1 release a couple of weeks ago. The bug introduces a crash whenever one is performing any of the following actions:
– Crashes when synthesizing a new design. A temporary solution is to return back to the newly created design which will now work normally since this bug only appears for newly created designs.
– Crash on design export (via email). Also seems to corrupt the selected design’s data, use this feature with caution.
Please comment below if you are experiencing issues with the app! I will update the software as soon as possible to support iOS 7 better, it will most likely be an iOS 7-only release since Apple has introduced a lot of changes to the SDK since the release of iOS 5 in 2011. The plan is to have these bugs resolved in 1-2 weeks time.
Thank you for your understanding and support, I am sorry for the inconvenience!
Edit (April 10): update 1.4 has been submitted to Apple for approval, which usually takes a week until it ends up in the AppStore. In addition to the bug fixes there are a couple of new features added and a fresh new interface.
Edit: Couplings Designer 1.4 now available on the AppStore.
