    Hi,
    I've tried building hello world with Qt 5.6 beta for iOS using Xcode 7.2 on El Capitain. But at runtime if I use a non-iOS 9.x device, I get an error about an unsupported forceTouchCapability in the Application Output:

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

    hit maximum number of consecutive signals, stopping
    Run ended.

    Has anyone else run into this problem?

    If I use Qt 5.5.1 then the app runs fine using the same build hw and device.

    I've raised a Qt bug about this too:
    https://bugreports.qt.io/browse/QTBUG-50650

    Any thoughts welcome...

      Looks like this bug has been found and fixed since 5.6 beta was released. I will double-check but then likely this should be marked as answered and fix will be in 5.6 release version :)
