    I tried again with a Hello world application from scratch. It still doesn't work. I didn't write a particular info.plist, so it was autogenerated by qmake. Application starts normally, but I don't get any dialog asking for permission to provide location and of course positionUpdated() still isn't emitted.

    I tried both real device and iOS Simulator with simulated location.
    Any ideas what else I should try?

      Maybe try examples available, like: "Weather Info"?

        Weather info doesn't work either. It just shows "Loading weather data" indefinitely.

          What version of iOS and Xcode are you using ? (latest can change pretty quickly)

            I have Xcode 7.1.1 and iOS 9.1 both on device and simulator. I added this information to the first post.

            I already verified that I can make a Hello World iOS app in XCode, which successfully obtains user position using native code (CLLocationManager).

              You might need to add the following keys to your plist

              • NSLocationAlwaysUsageDescription
              • NSLocationWhenInUseUsageDescription

              You also may need to add either of the following to your project file

              QT += positioning sensors

                I already implemented this using native code. But thanks. Maybe this helps somebody else.

                BTW I used the class CLLocationManager-blocks (https://github.com/axldyb/CLLocationManager-blocks). Thanks to this I was able to implement it by a brief Objective-C snippet in a QObject subclass. The position-update-handler was just an objective-C Block rather than Delegate. Writing the Delegate would have required to subclass NSObject.

                  @ldanzinger All you need to do in order to get QTPositioning to work is add <key>NSLocationAlwaysUsageDescription</key>
                  to your info.plist file.

                  create an iOS folder in the root of your project and place your info.plist file in there then add the following to you .pro file

                  ios {
                  QMAKE_INFO_PLIST = ios/Info.plist
                  }

                  This fixes the geoflickr example qt quick app.

                        I ask for the location at the begining of the program so it shows same time application starts.
                        Btw I did not add anything to my Info.plist, so I am not sure if it is required

                            Then check that you allowed the GPS to be used.

                                Then delete the application from your device and install it again. Do not just re-run your application, nuke it from the device before starting it again.
