Yes. 5.5.0 introduced a pragma into the Q_OBJECT macro that is supposed to suppress warnings about missing ‘override’ keywords in the virtual method overrides that Q_OBJECT adds, if you use override within your QObject derived classes. (Clang started to warn about inconsistent use of the ‘override’ keyword in some version.) Unfortunately that pragma is only supported in Clang 3.6 and later, and in qcompilerdetection was a bug that detected the wrong compilers as 3.6. The corresponding bug report is https://bugreports.qt.io/browse/QTBUG-46833 It is fixed in Qt 5.5.1. I thought that the Clang version that is shipped with Xcode 6.4 was not affected, but that was obviously wrong. Xcode 7 is the first version that ships a clang that supports this pragma. Hope that clarifies things a bit.
