Xcode not recognizing 3.0.1

by RentTesters on June 22, 2011

New service has been presented by SQA SOLUTION – iPhone Testing. iPhone App Testing is the most critical step in the iPhone application development process iPhone App Testing is the process of testing iPhone applications.

Apple has a technote about Xcode not recognizing 3.0.1 being installed on a phone, at:


The symlink was created in the right place, however Xcode still not working for 3.0.1 What do you have to do to get Xcode to recognize the update? It’s not viable to take every phone back to 3.0. Running the following command in terminal should fix it:
ln -s /Developer/Platforms/iPhoneOS.platform/DeviceSupport/3.0\ \(7A341\) /Developer/Platforms/iPhoneOS.platform/DeviceSupport/3.0.1

Here is the link to more info, including other versions:


You may also try the following steps

  1. Log into your Mac with an Admin account and launch the Terminal application
  2. Copy and paste the following line into Terminal:
    ln -s /Developer/Platforms/iPhoneOS.platform/DeviceSupport/3.0\ \(7A341\) /Developer/Platforms/iPhoneOS.platform/DeviceSupport/3.0.1

Note: If you installed iPhone SDK 3.0 somewhere other than the default /Developer
location, replace the “/Developer” directory as appropriate.

Several people have had to use this instead:
ln -s /Developer/Platforms/iPhoneOS.platform/DeviceSupport/3.0 /Developer/Platforms/iPhoneOS.platform/DeviceSupport/3.0.1

Here is a link to the advisory in PDF format:

open a Terminal and cd to “/Developer/Platforms/iPhoneOS.platform/DeviceSupport/”? Then run “ls -la” and paste the output into an email.

Mine is pasted below for reference. In particular, notice the symlink from “3.0.1” to “3.0 (7A341)”.

$ cd /Developer/Platforms/iPhoneOS.platform/DeviceSupport/

$ ls -la

I think I also had to restart Xcode to make this work.

These instructions will help you to XCode to work on 3.0.1
