iphone - How to solve Xcode 4.1 (LION) GPS error?

Question

My project worked perfectly on simulator+device,
but now, after upgrading to lion os and xcode 4.1, I get this error when gps is active!

server did not accept client registration 68

It's a gps based application, and i'm nervous to not debug app in simulator!

Any idea to solve this issue?

UPDATE: Gps on Simulator doesn't work also on Xcode 3.2.6 + LION.

Answer 1

Xcode 4.2 solved this problem adding custom gps position!

The file is an XML like this:

<?xml version="1.0"?>
<gpx version="1.1" creator="Xcode"> 
  <wpt lat="45,49939" lon="9,12114">
    <name>Milano</name>
  </wpt>
</gpx>

you can add this file in your project or New->File->GPX.

While you're running your app, activate the console and select your custom position file:

it's all.
enjoy.
