In that case please make sure to:
- Select the right target in Qt Creator (iphoneos-clang Qt 5.3.x for iOS; please note the *os instead of *simulator!), for publishing builds also select the release mode: https://i.imgur.com/5xcZ2tA.png
- Run qmake from the Build menu
- Open the Xcode project in the corresponding shadow build directory (named something like build-XYZ-iphoneos_clang_Qt_5_3_0_for_iOS-Release)
- Make sure to select the “iOS device” item (or your device if anyone plugged into your Mac) in the upper left menu: https://i.imgur.com/9wPIr25.png
We publish a proper deployment guide with our upcoming update the next few days, which will explain that in a detailed way. Hope this helps!
