QT Apps deployed in IOS8 crash

[stretch1790]

Hi there

I couldn't find an existing topic for this but I have just updated my test iPhone to IOS8. All QT applications that I deploy to my iPhone now crash instantly on load. All worked well when deployed onto a 7.1 based device. Any Ideas?

QT Version Info:

Qt Creator 3.1.2 (opensource)
Based on Qt 5.3.1 (Clang 5.0 (Apple), 64 bit)
Built on Jun 23 2014 at 04:15:49
From revision a791e851a7

IOS Version: 8.0 (12A365)

Below is the output from a really simple little QML based QTQuick application as it crashes:

QML debugging is enabled. Only use this in a safe environment.

hit maximum number of consecutive signals, stopping

Thanks in advance

I too encountered the given assert failure this morning, after updating XCode to 6.0.1 (6A317). An internet search yielded this recent patch ("remove numeric asserts"). This inspired me to uninstall Qt, then re-install a fresh download, which appears to have worked.

I just checked that I have the same problem.
As Urthas suggests, I'm downloading the latest version of Qt (5.3.2).
Thanks

Thanks Guys, Updating to 5.3.2 fixed the above issue for me.
