I just started working on a very similar project and had the exact same problem.

The solution is to go into your .pro file and add one single line of code...

symbian:TARGET.CAPABILITY += Location

This should be added in the

QML_IMPORT_PATH =

section.

So now mine looks like:

# Additional import path used to resolve QML modules in Creator's code model
QML_IMPORT_PATH =

symbian:TARGET.UID3 = 0xE6090127
symbian:TARGET.CAPABILITY += Location
