I think it

I was looking at accelbubble.pro example and noticed this:

ios {
QMAKE_INFO_PLIST = Info.plist

# manual plugin loading needed with older Qt
# QTPLUGIN += qsvg qtsensors_ios qtsensors_generic
}

accelbubble itself did not compile on iOS, but
I did a trivial QML test which just logs Accelerometer values.

If I add the line

QTPLUGIN += qtsensors_ios

to .pro it started to work!?
Is this documented somewhere?  On Android the plugin is not needed in .pro.
This is with Qt 5.4.1.  I wonder what the "older Qt" above means?

If someone could clarify this or point to documentation that would be nice.
Accelerometer documentation itself did not mention about any plugin 
requirements.
