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.

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 (https://qt.gitorious.org/qt/qtbase/commit/75cf14e413427f6687b895731f5b1294389c4dc7/diffs/3da75b05841e503c146a326c15b9065eebfe35b7) ("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.
