I can't reproduce this at all. I have now built iOS apps with the Intel XDK in the following combinations:
Reported .capx - new XDK project format - WKWebView - unminified
Reported .capx - new XDK project format - WKWebView - minified
sbperftest - new XDK project format - WKWebView - unminified
sbperftest - new XDK project format - old webview - unminified
sbperftest - old XDK project format - old webview - unminified
All five tests were exported with r227 and ran fine built by the Intel XDK running on an iPad Air 2 (iOS 9.3.1).
I'm guessing it might be one of these issues:
- are you testing on an older version of iOS? Maybe iOS 8?
- are you re-exporting over the same XDK project? I heard there are known bugs with that - I used a fresh project each time
- are you sure your build settings are all correct? I was testing with a newly configured certificate (it said something about being able to import an older certificate, but I couldn't build with that)
